3.16.66-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Zach Brown <zach.brown@xxxxxx>
commit b866203d872d5deeafcecd25ea429d6748b5bd56 upstream.
The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes an
autoneg failure case by resetting the hardware. This turns off
intterupts. Things will work themselves out if the phy polls, as it will
figure out it's state during a poll. However if the phy uses only
intterupts, the phy will stall, since interrupts are off. This patch
fixes the issue by calling config_intr after resetting the phy.
