[PATCH 06/22] fcoe: stop delivery of received frames before doing lport_destroy()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Joe Eykholt <jeykholt@xxxxxxxxx>

To be more sure that no more input arrives at the local port as
it is being destroyed, clean the queues in the per-cpu receive
threads.
