Subject: [dpdk-dev] [PATCH 3/3] ixgbe: allow use of zero MAC address with VF
Date: Wed, 24 Feb 2016 16:19:06 +0000	[thread overview]
Message-ID: <1456330746-15001-4-git-send-email-bernard.iremonger@intel.com> (raw)
In-Reply-To: <1456330746-15001-1-git-send-email-bernard.iremonger@intel.com>

Reprogram the RAR[0] with a zero MAC address,
to ensure that the VF traffic goes to the PF
after stop, close and detach of the VF.

Fixes: af75078fece3 ("first public release")
Fixes: 00e30184daa0 ("ixgbe: add PF support")
Signed-off-by: Bernard Iremonger <bernard.iremonger@intel.com>
