Subject: [patch 1/1] phy/marvell: fix 88e1121 support
Date: Mon, 18 Oct 2010 23:44:02 +0200	[thread overview]

Commit c477d0447db08068a497e7beb892b2b2a7bff64b added support for RGMII
rx/tx delays except that it ends up clearing rx/tx delays bit for modes
differents that RGMII*ID. Due to this, ethernet is not working anymore
on my guruplug server +. This patch is fixing that.
