ionic: add initial framework for XDP support
Set up the basics for running Rx packets through XDP programs.
Add new queue setup and teardown steps for adding/removing an
XDP program, and add the call to run the XDP on a packet.
The XDP frame size needs to be the MTU plus standard ethernet
header, plus head room for XDP scribblings and tail room for a
struct skb_shared_info. Also, at this point, we don't support
XDP frags, only a single contiguous Rx buffer. This means
that our page splitting is not very useful, so when XDP is in
use we need to use the full Rx buffer size and not do sharing.
