Revision 959eb39297e8c82f61fbfc283ad4ff11c883bf1e authored by Eli Cohen on 05 June 2006, 16:51:36 UTC, committed by Roland Dreier on 05 June 2006, 16:51:36 UTC 
IPoIB: Fix AH leak at interface down
 
When ipoib_stop() is called it first calls netif_stop_queue() to stop
the kernel from passing more packets to the network driver. However,
the completion handler may call netif_wake_queue() re-enabling packet
transfer.

This might result in leaks (we see AH leaks which we think can be
attributed to this bug) as new packets get posted while the interface
is going down.
