net: mana: Add support of XDP_REDIRECT action

Browse source

Add a handler of the XDP_REDIRECT return code from a XDP program. The
packets will be flushed at the end of each RX/CQ NAPI poll cycle.
ndo_xdp_xmit() is implemented by sharing the code in mana_xdp_tx().
Ethtool per queue counters are added for XDP redirect and xmit operations.
