bpf: make tun compatible w/ bpf_xdp_adjust_tail
w/ bpf_xdp_adjust_tail helper xdp's data_end pointer could be changed as well (only "decrease" of pointer's location is going to be supported). changing of this pointer will change packet's size. for tun driver we need to adjust XDP_PASS handling by recalculating length of the packet if it was passed to the TCP/IP stack (in case if after xdp's prog run data_end pointer was adjusted) Reviewed-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Nikita V.
