xdp: For Intel AF_XDP drivers add XDP frame_sz
Intel drivers implement native AF_XDP zerocopy in separate C-files,
that have its own invocation of bpf_prog_run_xdp(). The setup of
xdp_buff is also handled in separately from normal code path.
This patch update XDP frame_sz for AF_XDP zerocopy drivers i40e, ice
and ixgbe, as the code changes needed are very similar. Introduce a
helper function xsk_umem_xdp_frame_sz() for calculating frame size.
