Let me try and clear it. First OFED version introduced in FreeBSD9 was indeed ofed-1.5.3.=20 Future updates were based on Linux kernel and not the OpenFabrics versionin= g system. FreeBSD11 should currently have something similar to Linux v3.10 if I'm not= mistaken. Last big update in FreeBSD12 was based on Linux v4.9. Hopefully we can MFC it completely to FreeBSD11-STABLE. Last but not least - Yes, HEAD supports RoCEv2. Meny Hi Meny, Thanks a lot for the reply and the information. I have couple of additional questions. > 4.

Is RoCE v2 supported of FreeBSD 11 release or 11_stable ? [MY] Not currently, though we do have plans adding it in the near future 2. How does one figure out the OFED version in a FreeBSD kernel? [MY] Unfortunately, OFED version is not maintained. Some files do state a v= ersion, but I wouldn't trust that too much 3. Since OFED on HEAD is synced to Linux 4.9 in kernel.org, I presume th= at it is OFED version 4.8. Am I correct ? [MY] 4.9+ 4. Am I correct that the OFED version on FreeBSD 11 is 1.5.3 ? [MY] No. We did an upgrade in FreeBSD11 a while back. If I'm not mistaken, = FreeBSD11's OFED is currently based on version 2.0+ 5. Are there any plans to backport OFED from HEAD to Stable_11?
