Subject: [PATCH 08/10] [PATCH] skge: set mac address oops with bonding
Date: Thu, 29 Sep 2005 19:20:24 -0700	[thread overview]
Message-ID: <20050930022242.010635000@localhost.localdomain> (raw)
In-Reply-To: 20050930022016.640197000@localhost.localdomain

[-- Attachment #1: skge-set-mac-address-oops-with-bonding.patch --]
[-- Type: text/plain, Size: 1907 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

Here is the patch (fuzz removed) for 2.6.13.2 that fixes
OOPs when using bonding with skge.

Skge driver was bringing link up/down when changing mac
address.  This doesn't work in the bonding environment, and is
more effort than needed.
