On the Netgear WNDAP620, the emac ethernet isn't receiving nor xmitting any frames from/to the RTL8363SB (identifies itself as a RTL8367RB). This is caused by hardware not knowing the right forced link settings (speed, duplex, pause, etc.) settings. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
