Don't build krping.ko, iw_cxgb.ko, and iw_cxgbe.ko, if MK_OFED=no (the default). They build, but are unloadable, due to missing ibcore.ko. Sponsored by: FreeBSD Foundation 2013-10-18 09:17:35 +00:00
sys/modules: normalize .CURDIR-relative paths to SRCTOP This simplifies make output/logic Tested with: `cd sys/modules; make ALL_MODULES=` on amd64 MFC after: 1 month Sponsored by: Dell EMC Isilon 2017-03-04 10:10:17 +00:00			`SYSDIR?=${SRCTOP}/sys`
Remove dependence on source tree options. Move all kernel module options into kern.opts.mk and change all the places where we use src.opts.mk to pull in the options. Conditionally define SYSDIR and use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all instances of CURDIR/../../etc with STSDIR, but only in the affected files. As a special compatibility hack, include bsd.owm.mk at the top of kern.opts.mk to allow the bare build of sys/modules to work on older systems. If the defaults ever change between 9.x, 10.x and current for these options, however, you'll wind up with the host OS' defaults rather than the -current defaults. This hack will be removed when we no longer need to support this build scenario.

Move NIC driver (cxgb) into its own directory. Add toecore to support registering different TOMs. 2007-12-15 22:03:19 +00:00			`SUBDIR= cxgb`
- 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.
