After commit a058052c358c
("net: phy: do not read configuration register on reset")
both 3c120 and 10m50 devboard which use Marvel m88e1111s PHY got this
error message,
Net: eth0: ethernet at 400
=> ping 192.168.1.5
ethernet at 400 Waiting for PHY auto negotiation to complete.... TIMEOUT !
Using ethernet at 400 device
host 192.168.1.5 is alive
This is because the auto negotiation control bit was cleared by the new
phy_reset(). But the m88e1111s_config() does the soft-reset already,
there is no need to reset twice. The extra phy_reset() should be
removed.
