net: fec: add initial XDP support
This patch adds the initial XDP support to Freescale driver. It supports
XDP_PASS, XDP_DROP and XDP_REDIRECT actions. Upcoming patches will add
support for XDP_TX and Zero Copy features.
As the patch is rather large, the part of codes to collect the
statistics is separated and will prepare a dedicated patch for that
part.
I just tested with the application of xdpsock.
-- Native here means running command of "xdpsock -i eth0"
-- SKB-Mode means running command of "xdpsock -S -i eth0"
The following are the testing result relating to XDP mode:
