Subject: [PATCH 4/4] drivers/net: enic: Generate notification of hardware crash
Date: Fri,  9 Aug 2013 11:38:55 -0700	[thread overview]
Message-ID: <1376073535-17154-5-git-send-email-neepatel@cisco.com> (raw)
In-Reply-To: <1376073535-17154-1-git-send-email-neepatel@cisco.com>

This patch generates a hardware crash notification (NETDEV_REBOOT)
during reset. After a hardware crash, ENIC resets all its resources
including queue pair filters programmed by USNIC. USNIC registers for
this notification, and on receiving it, reprograms the queue pair filters.
