Don't mask bit 4 of the AT8022 phy id. If bit 4 of the AT8022 phy id (0x004dd023) is masked, it will match the phy id of the AR8327 switch (0x004dd033) as well. It results in applied at803x driver settings/callbacks, which will at least limit the AR8327 phys to 100MBit operation instead of the possible 1000MBit. Signed-off-by: Mathias Kresin <dev@kresin.me>

Subject: net: phy: at803x: add support for AT8032
|
|
|
|
Like AT8030, this PHY needs the GPIO reset workaround
