[PATCH 3/7] net: enc28j60: replace global NetRxPackets with per-interface allocation

[Ahmad Fatoum]

NetRxPackets is a remnant of times, where a board had at most one
Ethernet controller. This is outdated and we should drop NetRxPackets.

The driver doesn't maintain a queue of packets, so let's just allocate
it per interface.
