Date: Thu, 04 Feb 2010 17:56:53 +0200
From: Yevgeny Petrilin <yevgenyp@...lanox.co.il>
To: Roland Dreier <rdreier@...co.com>
CC: general@...ts.openfabrics.org, netdev@...r.kernel.org,

Subject: [PATCH 19/23 v3] mlx4: SET port for Ethernet moved to mlx4_core
The physical port is common resource for all the functions.
Its management should go through the multifunction mechanism.
