[ofw][patch] port_info record

[Slava Strebkov]

When SM configures port to have more than one LID (according to LID mask
control), the query of IB_MAD_ATTR_PORTINFO_RECORD fails. That's because
of IB switch has more information to answer, but query configured as
IB_MAD_METHOD_GET. So IB switch return error. Consequently, port becomes
inactive (see ipoib_port_up) and Network properties show adapter as
disconnected.
Setting  info.method = IB_MAD_METHOD_GETTABLE fixed the problem.

Can you provide more details _how_ it fixes the problem?  I can't tell
just by looking at the patch.

Is IPoIB ready to handle an RMPP response to this request?
