The Atheros 8031 PHY supports the 802.3 extension for symmetric and
asymmetric pause frames, so set that to the list of features supported
by the phy.

Without this patch, my NIC (the Qualcomm EMAC) receives a lot of frame
check sequence (aka CRC) errors, resulting in about 10% packet loss.
Can someone help me understand why? Because of this patch, I can't use
the generic phy driver in phylib. Why would a MAC controller require
its PHY to support pause frames?
