The tx bytecount is done twice. When running
'./xdpsock -t -N -i eth3' and 'ip -s link show dev eth3'
The avg packet size is 120 instead of 60. So remove the
extra one.

The total_packets count at ixgbe_clean_xdp_tx_irq is
always zero when testing with xdpsock -t -N. Set the gso_segs
to 1 to make the tx packet count correct.

[ +Jeff ]
Given these two are contained to ixgbe, I presume Jeff wants to pick
these up instead via his tree?

Yes, I will be picking them up.
