From: Lance Richardson <[email protected]>
When determining whether scattered receive mode is needed, the
size of a QinQ header is being added to rxmode.max_rx_pkt_len
before comparing to the receive buffer size, however max_rx_pkt_len
already accounts for the QinQ header size. Fix by simply comparing
rxmode.max_rx_pkt_len against the buffer size.
