net: systemport: Avoid RBUF stuck in Wake-on-LAN mode
After a number of suspend and resume cycles, it is possible for the RBUF to be stuck in Wake-on-LAN mode, despite the MPD enable bit being cleared which instructed the RBUF to exit that mode. Avoid creating that problematic condition by clearing the RX_EN and TX_EN bits in the UniMAC prior to disable the Magic Packet Detector logic which is guaranteed to make the RBUF exit Wake-on-LAN mode.
