Subject: IPoIB: Only handle async events for one port
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a27cbe878203076247c1b5287f5ab59ed143b560;p=linux-beck.git

IPoIB: Only handle async events for one port

An asynchronous event carries the port number that the event occurred
on, so there's no reason for an IPoIB interface to process an event
associated with a different local HCA port.
