This patch series adds XDP support for the igc driver. The approach implemented
by this series follows the same approach implemented in other Intel drivers as
much as possible for the sake of consistency.
The series is organized in two parts. In the first part, i.e. patches from 1 to
5, igc_main.c and igc_ptp.c code is refactored in preparation for landing the
XDP support, which is introduced in the second part (patches from 6 to 9).
As far as code organization is concerned, XDP-related helpers are defined in a
new file, igc_xdp.c, and are called by igc_main.c.
The features added by this series have been tested with the samples provided in
samples/bpf/: xdp1, xdp2, xdp_redirect_cpu, and xdp_redirect_map.
Upcoming series will add support of UMEM and zero-copy features from AF_XDP.
