[PATCH bpf-next v3 04/11] bpf: make bnxt 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 bnxt driver we will just calculate packet's length unconditionally Acked-by: Alexei Starovoitov
