if_atsam: Recover from receive freezes
Under unknown conditions the receive path ended up in a frozen state.
In this state, the DMA and driver descriptor head were equal and all
receive descriptors had the used bit set. So, the DMA was unable to
store received frames. However, the receive daemon was never woken up
to refill the receive buffers. It seems that the RXUBR interrupt can be
used to recover from this state.
Update #4651.
