From 7097228c54e7348d8c8c6dccc96e50191e39c2f8 Mon Sep 17 00:00:00 2001 From: Michael Brooks Date: Sat, 20 Sep 2008 20:06:16 -0700 Subject: [PATCH] IB/mad: Don't discard BMA responses in kernel This fixes the problem of incoming BMA responses being dropped due to a bad "is response" check. Fix the test to use the ib_response_mad() predicate, which correctly handles BMA MADs. This fixes .
