Message-Id: <1352196533-2674-1-git-send-email-steve.glendinning@shawell.net> Date: Tue, 6 Nov 2012 10:08:53 +0000 From: Steve Glendinning <steve.glendinning@...well.net> To: netdev@...r.kernel.org Cc: Steve Glendinning <steve.glendinning@...well.net> Subject: [PATCH 2/2] smsc95xx: set MII_BUSY bit to read/write PHY regs The device datasheet specifies the BUSY bit must be set when reading or writing phy registers. This patch ensures we do that.
