 Cloned from #4651:
 ----
 The if_atsam network interface driver has several issues. Do not disable
 the FCS if the checksum offload is disabled. Make sure the interface
 capabilities are enabled. Add multicast and VLAN support. Use the
 interface transmit method instead of the interface start approach. Correct
 a potential receive starvation error. Fix the interface up/down.
