[openib-general] [PATCH] IB/ipoib: user appropriate mtu selector for path queries

[Roland Dreier]

Seems OK from an anal spec compliance point of view, but I don't
understand this:

 > This breaks IPoIB on networks with SM Tavor quirk activates.

Even if opensm returns a path record with a lower MTU, the underlying
links still have a 2K mtu really, so nothing breaks.  IPoIB is just
doing something naughty by ignoring the MTU in the path record.  So
what breaks really?

(not to mention the fact that the "Tavor quirk" hasn't been accepted
into OpenSM yet anyway)
