[net-next PATCH v3 1/3] e1000: track BQL bytes regardless of skb or not

[John Fastabend]

The BQL API does not reference the sk_buff nor does the driver need to
reference the sk_buff to calculate the length of a transmitted frame.
This patch removes an sk_buff reference from the xmit irq path and
also allows packets sent from XDP to use BQL.
