[PATCH] net: phy: fix phy device autoneg wrong value

From: Nicolae Rosia
Date: Thu Jan 22 2015 - 13:11:59 EST


In phy_device_create, autoneg is set to AUTONEG_ENABLE.
When using the generic phy driver (phy_device.c),
genphy_config_init reads BMSR and finds out if autonegotiation
is possible and sets the phy device features accordingly.
phy_sanitize_settings is supposed to set the right value of
autoneg, but it is never called if autonegotiation is enabled,
which is always the case.
