ENGR00176347-9 fec : increase wait time for phy link
- remove the excrescent code in enet_board_init function.
- KSZ9021 phy auto-negotiation in mx6solo sabreauto RevA
is used to establish link with the remote hub or switch.
In general, the negotiation time is about 3-5 senconds
But connecting to Gbps hub, the time
is range from 8s to 15s. So, changing the MAX link waiting time
to 20s.
According to repetitious tests, solo ARD ethernet is ok in 100Mbps
environment. It is not stable in 1000Mbps mode.
