Subject: [PATCH net-next 13/21] ethernet, sfc: convert to standard XDP stats
Just like DPAA2 driver, EF{100,X} store XDP stats per-channel, but
present them as the sums across all channels.
Switch to the standard per-channel XDP stats. n_rx_xdp_bad_drops
goes as "general XDP errors", because driver uses just one counter
for all kinds of errors.
