[openib-general] [PATCH] RFC libibverbs, pass AEs to provider library.

[Steve Wise]

Roland,

This is just an RFC patch (untested).  

I'm adding bypass support to a device and have a need to know whenever
an async event is delivered to the consumer.  It allows the bypass
library to do WQ or CQ processing that needs to happen when a fatal
async event happens.  This async callback is similar to the cq_event
callback that already exists in libibverbs.  

If you think this is reasonable, then I'll submit a tested patch.  

Steve.
