Subject: [PATCH net-next v5 06/22] bnx2x: Add teardown_q and close to VF <-> PF channel
Date: Tue, 1 Jan 2013 17:22:28 +0200 [thread overview]
Message-ID: <1357053764-8187-7-git-send-email-ariele@broadcom.com> (raw)
In-Reply-To: <1357053764-8187-1-git-send-email-ariele@broadcom.com>
When a VF is being closed its queues are released via
the 'teardown_q' and the VF itself is closed with
'close'. These are essentially the unload counterparts of
'init' and 'setup_q' from the load flow.
