From: Michael Chan Date: Thu, 3 May 2007 20:22:52 +0000 (-0700) Subject: [BNX2]: Put MII register offsets in the bnx2 struct. X-Git-Tag: v2.6.22-rc1~1036^2~22 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca58c3af99b15f729e56dffe9b74b8b2ce157e8d;p=linux-2.6 [BNX2]: Put MII register offsets in the bnx2 struct. The 5709 Serdes device uses non-standard MII register offsets. This re-structuring will make it easier to support 5709 Serdes. Signed-off-by: Michael Chan Signed-off-by: David S.
