[ewg] [PATCH] IB/ipoib - Problem with latest OFED 1.3 build... IPoIB and iPATH

[Ralph Campbell]

Here is a suggested patch for ib_ipoib for fixing the OFED-1.3 RC4
problem with ib_ipath.

Note that I'm not completely familiar with all the ib_ipoib changes.
In particular, I haven't checked that IB_EVENT_LID_CHANGE correctly
updates priv->own_ah.
