Raw Normal View History

- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications. MFC after: ~3 months (after 9.1, and after ensuring MFC is feasible)

cxgbe/t4_tom: Per-connection rate limiting for TCP sockets handled by the TOE. For now this capability is always enabled in kernels with options RATELIMIT. t4_tom will check if_capenable once the base driver gets code to support rate limiting for any socket (TOE or not). This was tested with iperf3 and netperf ToT as they already support SO_MAX_PACING_RATE sockopt. There is a bug in firmwares prior to 1.16.45.0 that affects the BSD driver only and results in rate-limiting at an incorrect rate. This will resolve by itself as soon as 1.16.45.0 or later firmware shows up in the driver. Relnotes: Yes Sponsored by: Chelsio Communications
