[ofa-general] [PATCH] ib/srp: add QoS support through service ID

[Sean Hefty]

Provide the target service ID when performing a path record query to
support optional QoS capability.  QoS requires support from the SA.

This change was way easier than I expected.  It compiles with the
appropriate changes to the ib_sa that Roland mentioned earlier.  Once we
can converge on all the host stack changes for QoS, I'll push them out to
my git tree.
