Hi,
The bsd_rdma_4_9_stable_11 projects branch is close to being merged into
FreeBSD 11-stable. Mellanox plans to merge no later than 12:00 CEST TUE
20th of March 2018, unless objections are received.
A compatibility header file has been created, ib_verbs_compat.h, which
offers full source compatibility to existing OFED kernel applications,
as a response to the raised conserns. User-space compatibility is
maintained through library symbol versioning.
https://svnweb.freebsd.org/base/projects/bsd_rdma_4_9_stable_11/sys/ofed/include/rdma/ib_verbs_compat.h
An example client for this header file can be found here:
https://svnweb.freebsd.org/base/projects/bsd_rdma_4_9_stable_11/sys/contrib/rdma/krping_compat/
Currently the cxgb and cxgbe i-Warp drivers are not building, and will
be stubbed from the kernel build before the branch is merged, unless
Chelsio can add patches for these.
Here is a quick and dirty patch to make the bsd_rdma_4_9_stable_11
branch build:
