For MFC, pci_iov_if.h is excluded from the list. It will be readded when linuxkpi support for SRIOV is merged.

The OFED kernel option no longer builds the LinuxKPI into the kernel. This was done to keep the build rules for the LinuxKPI in sys/conf/files simple. - Extend the LinuxKPI module to include support for USB by moving the Linux USB compat from usb.ko to linuxkpi.ko. - Bump the FreeBSD_version. - A universe kernel build has been done.

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.
