Miller 1275863927 -0700 r8169: fix random mdio_write failures Some configurations need delay between the "write completed" indication and new write to work reliably. Realtek driver seems to use longer delay when polling the "write complete" bit, so it waits long enough between writes with high probability (but could probably break too). This patch adds a new udelay to make sure we wait unconditionally some time after the write complete indication. This caused a regression with XID 18000000 boards when the board specific phy configuration writing many mdio registers was added in commit 2e955856ff (r8169: phy init for the 8169scd). Some of the configration mdio writes would almost always fail, and depending on failure might leave the PHY in non-working state.
