cxgbetool(8): Add a subaction (tcbrss <n>) that can be used with "pass" action to distribute traffic using the half of the VI's RSS indirection table. The value specified should either be the start of the VI's RSS slice (available at dev.<ifname>.<inst>.rss_base since r339700) or the midpoint (rss_base + rss_size/2). The traffic that hits the filter will use the first or second half of the indirection table respectively. The indirection table can be populated in different ways to achieve different kinds of traffic/load distributions. For example, r339749 allows a netmap interface to have half the rx queues in the first half of the table and the rest in the other. Sponsored by: Chelsio Communications
cxgbetool(8): The VLAN tag provided in the action for a filter must be prefixed with either '=' or '+'. Fix the description of the parameter in the man page while here. Approved by: re@ (kib@) Sponsored by: Chelsio Communications
cxgbetool(8): Userspace part of support for high priority filters on T6+. MFC after: 1 week Sponsored by: Chelsio Communications
cxgbetool(8): Require and validate only those inputs that are applicable to the type of rate limiter being configured. For example, the class WRR scheduler doesn't need any kbps limits (it just needs the weights for each class), the channel scheduler doesn't need anything except the aggregate kbps to limit the channel to, and so on. MFC after: 3 days Sponsored by: Chelsio Communications
cxgbetool(8): Reject invalid VLAN values. Submitted by: Krishnamraju Eraparaju @ Chelsio MFC after: 1 week Sponsored by: Chelsio Communications
cxgbetool: Disallow negative values for numeric parameters. Sponsored by: Chelsio Communications
Re-apply r190640. - Restore local change to include <net/bpf.h> inside pcap.h. This fixes ports build problems. - Update local copy of dlt.h with new DLT types. - Revert no longer needed <net/bpf.h> includes which were added as part of r334277. Suggested by: antoine@, delphij@, np@ MFC after: 3 weeks Sponsored by: Mellanox Technologies
MFV r333789: libpcap 1.9.0 (pre-release) MFC after: 1 month Sponsored by: Mellanox Technologies
cxgbetool(8): Provide user interface for hashfilters, hardware NAT, and other filtering related features that were recently added to the driver. Sponsored by: Chelsio Communications
cxgbe(4): Add support for Connection Offload Policy (aka COP). COP allows fine-grained control on whether to offload a TCP connection using t4_tom, and what settings to apply to a connection selected for offload. t4_tom must still be loaded and IFCAP_TOE must still be enabled for full TCP offload to take place on an interface. The difference is that IFCAP_TOE used to be the only knob and would enable TOE for all new connections on the inteface, but now the driver will also consult the COP, if any, before offloading to the hardware TOE. A policy is a plain text file with any number of rules, one per line. Each rule has a "match" part consisting of a socket-type (L = listen, A = active open, P = passive open, D = don't care) and a pcap-filter(7) expression, and a "settings" part that specifies whether to offload the connection or not and the parameters to use if so. The general format of a rule is: [socket-type] expr => settings Example. See cxgbetool(8) for more information. [L] ip && port http => offload [L] port 443 => !offload [L] port ssh => offload [P] src net 192.168/16 && dst port ssh => offload !nagle !timestamp cong newreno [P] dst port ssh => offload !nagle ecn cong tahoe [P] dst port http => offload [A] dst port 443 => offload tls [A] dst net 192.168/16 => offload !timestamp cong highspeed The driver processes the rules for each new listen, active open, or passive open and stops at the first match. There is an implicit rule at the end of every policy that prohibits offload when no rule in the policy matches: [D] all => !offload This is a reworked and expanded version of a patch submitted by Krishnamraju Eraparaju @ Chelsio.

cxgbetool(8): Add the ability to decode hardware TCBs. Obtained from: Chelsio Communications MFC after: 1 week Sponsored by: Chelsio Communications
cxgbetool(8): Do not close uninitialized fd on malloc failure. MFC after: 1 week Sponsored by: Chelsio Communications
cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. MFC after: 2 weeks Sponsored by: Chelsio Communications
cxgbetool(8): mode must be specified when creating the dump file. MFC after: 1 week Sponsored by: Chelsio Communications
cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. Obtained from: Chelsio Communications MFC after: 2 months Sponsored by: Chelsio Communications
cxgbetool(8): Add loadboot and loadboot-cfg subcommands to install or remove bootrom and boot config. MFC after: 2 weeks Sponsored by: Chelsio Communications
Add cxgbetool(8) to the base system. Move cxgbetool from tools/tools to usr.sbin. Compile and install it on platforms where cxgbe(4) is built by default. Knobs (WITH_CXGBETOOL and WITHOUT_CXGBETOOL) have been added so that the user can override the default setting. Reviewed by: ngie@, gnn@, bdrewery@ MFC after: 1 month Sponsored by: Chelsio Communications Differential Revision: https://reviews.freebsd.org/D9854
cxgbetool: Add a loadcfg subcommand to allow a user to upload a firmware configuration file to the card.
Fix typo.
cxgbetool: Add T6 support to the SGE context decoder. Obtained from: Chelsio Communications Sponsored by: Chelsio Communications
cxgbetool: Allow max-rate > 10Gbps for rate-limited traffic. Sponsored by: Chelsio Communications
cxgbe(4): Overhaul the shared code that deals with the chip's TP block, which is responsible for filtering and RSS. Add the ability to use filters that match on PF/VF (aka "VNIC id") while here. This is mutually exclusive with filtering on outer VLAN tag with Q-in-Q. Sponsored by: Chelsio Communications
cxgbe(4): Updated register dumps. - Get the list of registers to read during a regdump from the shared code instead of the OS specific code. This follows a similar move internally. The shared code includes the list for T6. - Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register dumps (and catch up with some updates to T4 and T5 register decode). Obtained from: Chelsio Communications Sponsored by: Chelsio Communications
Fix some whitespace nits in cxgbetool.c. No functional change.
- Replace N(a)/N(i)/N(T)/LEN(a)/ARRAY_SIZE(a) with nitems() - Add missing <err.h> for err() and <sys/sysctl.h> for sysctlbyname() - NULL -> 0 for 5th parameter of sysctlbyname() Submitted by: Andriy Voskoboinyk <s3erios@gmail com> Differential Revision: https://reviews.freebsd.org/D3442
cxgbetool: fix code that decodes T5 SGE contexts. Some of the fields that changed between T4 and T5 were not displayed correctly. Obtained from: Chelsio MFC after: 3 days Differential Revision:
cxgbetool: Catch up with r185979. One of MAP_ANON, MAP_PRIVATE, MAP_SHARED, or MAP_STACK must be specified. This fixes the "loadfw" subcommand. MFC after: 1 week
Add a 'raw' parameter to the 'modinfo' subcommand. This is handy when trying to figure out why a QSFP+/SFP+ connector or cable wasn't identified correctly by cxgbe(4). Its output looks like this: # cxgbetool t5nex0 modinfo 0 raw 00: 03 04 21 00 00 00 00 00 ..!. .... 08: 04 00 00 00 67 00 00 00 .... g... 10: 00 00 05 00 41 6d 70 68 ....

cxgbetool: Display the congestion channel map in hex. MFC after: 1 week
Two new cxgbetool subcommands to set up scheduler classes and to bind them to NIC queues. Obtained from: Chelsio
cxgbetool: "modinfo" command to display SFP+ module information. trantor:~# cxgbetool t5nex0 modinfo 1 ID: SFP Vendor FINISAR CORP. SN AJ10JQR PN FTLX8571D3BCL Rev A Temp: +35C Vcc 3.225600V TX Bias 2.176000uA TX Power 0.588800mW RX Power 0.486400mW Submitted by: gnn
Teach cxgbetool to display T5 congestion manager context.
Add support for packet-sniffing tracers to cxgbe(4). This works with all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and for general purpose monitoring without tapping any cxgbe or cxl ifnet directly. Tracers on the T4/T5 chips provide access to Ethernet frames exactly as they were received from or transmitted on the wire. On transmit, a tracer will capture a frame after TSO segmentation, hw VLAN tag insertion, hw L3 & L4 checksum insertion, etc. It will also capture frames generated by the TCP offload engine (TOE traffic is normally invisible to the kernel). On receive, a tracer will capture a frame before hw VLAN extraction, runt filtering, other badness filtering, before the steering/drop/L2-rewrite filters or the TOE have had a go at it, and of course before sw LRO in the driver. There are 4 tracers on a chip. A tracer can trace only in one direction (tx or rx). For now cxgbetool will set up tracers to capture the first 128B of every transmitted or received frame on a given port. This is a small subset of what the hardware can do. A pseudo ifnet with the same name as the nexus driver (t4nex0 or t5nex0) will be created for tracing. The data delivered to this ifnet is an additional copy made inside the chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual. /* watch cxl0, which is the first port hanging off t5nex0. */ # cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting) # cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving) # cxgbetool t5nex0 tracer list # tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K "frames" with no L3/L4 checksum but this will show you the frames that were actually transmitted. /* all done */ # cxgbetool t5nex0 tracer 0 disable # cxgbetool t5nex0 tracer 1 disable # cxgbetool t5nex0 tracer list # ifconfig t5nex0 destroy
Count the number of hits for a filter by default. MFC after: 3 days
Set and display the IP fragment bit correctly when dealing with the filter mode. MFC after: 3 days.
cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio
Fix compile warning by including ctype.h for isdigit(). MFC after: 1 day
Allow "ivlan" (inner VLAN) to be used as an alias for "vlan" when specifying match criteria. "vlan" continues to be valid here, and it continues to be valid when deleting, rewriting, inserting, or stacking an 802.1q tag to a matching packet. MFC after: 3 days
Add a "clearstats" subcommand to cxgbetool that lets you clear the MAC statistics for any port. For example: # cxgbetool t4nex0 clearstats 0 Submitted by: gnn@ MFC after: 3 days
Add an "i2c" subcommand to cxgbetool. You can use this to read information from the transceivers connected to the ports of a cxgbe(4) based card. # cxgbetool t4nex0 i2c <port_id> <dev_addr> <addr> [<count>] For example: # cxgbetool t4nex0 i2c 0 0xa0 3 0x10 [16] (As per SFF-8472 the SFP+ module is at 0xa0 and bit 4 in the value at address 3 indicates it's a 10Gbase-SR module, which it is.)
Catch up with new driver ioctls in cxgbe. MFC after: 1 month
Many updates to cxgbe(4)
- Device configuration via plain text config file. Also able to operate
when not attached to the chip as the master driver.
- Generic "work request" queue that serves as the base for both ctrl and
ofld tx queues.
- Generic interrupt handler routine that can process any event on any
kind of ingress queue (via a dispatch table).
- A couple of new driver ioctls. cxgbetool can now install a firmware
to the card ("loadfw" command) and can read the card's memory
("memdump" and "tcb" commands).
- Lots of assorted information within dev.t4nex.X.misc.* This is
primarily for debugging and won't show up in sysctl -a.
- Code to manage the L2 tables on the chip.
- Updates to cxgbe(4) man page to go with the tunables that have changed.
- Updates to the shared code in common/
- Updates to the driver-firmware interface (now at fw 1.4.16.0)
MFC after: 1 month
Add "context" subcommand to fetch and display SGE context.
cxgbetool: a tool for the cxgbe(4) driver.
