[U-Boot-Users] [PATCH] net: uec_phy: handle 88e1111 rev.B2 erratum 5.6

[Kim Phillips]

erratum 5.6 states the autoneg completion bit is functional only if the
autoneg bit is asserted.

This fixes any secondarily-issued networking commands on non-gigabit
links on the mpc8360 mds board.

gvb, please test, and give us your blessings if this fixes your second
ping failing issue.

To go through biggerbadderben, for 1.3.2.
