Summary

This allows the "irdma" driver to communicate with the ice(4)
driver to allow it access to the underlying device's hardware
resources as well as synchronize access to shared resources.

This interface already existed in the standalone out-of-tree
1.34.2 driver; this commit adds and enables it in the in-kernel
driver.

Eric,

I donot see "irdma" available yet in FreeBSD ?

Do you mean in-kernel? It's currently available as an OOT module here:

Yes, I meant in-tree-kernel version. Do you have plan to upstream OOT irdma driver ?

I think we plan on doing an upstream version, but I don't know the timeline yet. I'll have to talk to the FreeBSD RDMA developer.

We'll hold off on doing anything with this until we're ready to upstream the actual RDMA driver and associated code; there may be some more changes identified.

Update with latest driver version's interface; now based on 1.34.2-k.

sys/modules/ice/Makefile
20	We added a hack to the ice module Makefile to compile interface/.m files. These are required for the RDMA client interface, but they don't build as-is like the normal .c files. The source directory doesn't seem to be included by default, so add lines that specifically add them as libraries so that ice_rdma.h can be found and the interface files will compile.
