cm_opa_to_ib_sgid(9)

💖 NAME 💖

okay so bestie, welcome to the cm_opa_to_ib_sgid(9) page in the Kernel API Manual ✨ the main-character function here is cm_opa_to_ib_sgid — Convert OPA SGID to IB SGID.

and why do we care? because ULPs (such as IPoIB) do not understand OPA GIDs and will reject them, since the local_gid will not match the sgid. therefore, the move is literally to change the pathrec's SGID to an IB SGID. periodt 💅

✨ SYNOPSIS ✨
