This patch set prepares for supporting af-xdp zerocopy.
There is no feature change in this patch set.
I just want to reduce the patch num of the final patch set,
so I split the patch set.

Thanks.

v2:
    1. Add five commits. That provides some helper for sq to support premapped
       mode. And the last one refactors distinguishing xmit types.

v1:
    1. resend for the new net-next merge window
