netxen: ethtool statistics and control for LRO
Add ethtool -K knob to control LRO in firmware.
LRO path is completely separated from GRO, LRO packets
are still fed with netif_receive_skb().
Also fix ethtool statistics to include LRO packets.
Also use correct message type while configuring interrupt coalescing.
