So it looks like e1000_xmit_raw_frame() can return early,
say if there is no available descriptor.

This patch adds initial support for XDP on e1000 driver. Note e1000
driver does not support page recycling in general which could be
added as a further improvement. However XDP_DROP case will recycle.
XDP_TX and XDP_PASS do not support recycling yet.
I tested this patch
