[ofa-general] [PATCH 2/4] ib/sa: add new QoS fields to path record

[Roland Dreier]

 > Can someone explain how iser and srp find the target devices?

SRP uses IB device management to discover target ports.  This is done
in userspace and passed into the kernel - the kernel gets the dest
GID, P_Key and service ID to use, and looks up a path record to
actually connect (using the IB CM, since SRP is "native" on IB and
doesn't use IP addressing at all, so the RDMA CM doesn't apply).
