ucc_geth: Fix the wrong the Rx/Tx FIFO size
current the Rx/Tx FIFO size settings cause problem when four UEC ethernets work simultaneously. eg: GETH1, UEM-J15, GETH2, UEC-J5 on 8569MDS board $ ifconfig eth0 10.193.20.166 $ ifconfig eth1 10.193.20.167 $ ifconfig eth2 10.193.20.168 then $ ifconfig eth3 10.193.20.169 The fourth ethernet will cause all of interface broken, you cann't ping successfully any more. The patch fix this issue for MPC8569 Rev1.0 and Rev2.0 Signed-off-by: Dave Liu <daveliu@freescale.com> Acked-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.
