The bug was fixed in kernel 4.14 and now the feature is supported, the
legacy value 1 on resp.support_multi_pkt_send_wqe is not reported from
kernel any more as we can't rely on, and a new bit MLX5_ALLOW_MPW (1 << 1)
was introduced to indicate that feature is supported.
That is very messy.. At least delete the MLX5DV_CONTEXT_FLAGS_MPW
constant to create a compile failure for this break.
PR was updated as you suggested, series was merged.
