From d3ea4d7258316ca68ff104087a5f1987b4829339 Mon Sep 17 00:00:00 2001 From: Fugang Duan Date: Sat, 10 Mar 2012 15:59:42 +0800 Subject: 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.
