[openib-general][PATCH] mthca & ib_verbs.h client reregister event support

[Leonid Arsh]

Of course, the FW doesn't handle the event, it handles the request by 
sending the port info to the SM.
It also generates an appropriate event to SW. The actual re-registration 
is to be done by the SW in ULPs.
An alternative way to generate the event is catching the request MAD in 
smp_snoop, as you suggested, but the port info still will be sent by the 
FW.
