Subject: [PATCH net-next 11/21] ethernet, mvpp2: rename xdp_xmit_err to xdp_xmit_drops
xdp_xmit_err stat is defined as num_frames - nxmit in
.ndo_xdp_xmit() callback implementation, and regarding that the
frames which weren't transmitted are treated as drops by BPF core,
give it a more fitting name in preparation for switching to standard
XDP stats.
