====================
DSA tagger helpers

The goal of this series is to minimize the use of memmove and skb->data
in the DSA tagging protocol drivers. Unfiltered access to this level of
information is not very friendly to drive-by contributors, and sometimes
is also not the easiest to review.

For starters, I have converted the most common form of DSA tagging
protocols: the DSA headers which are placed where the EtherType is.

The helper functions introduced by this series are:
- dsa_alloc_etype_header
- dsa_strip_etype_header
- dsa_etype_header_pos_rx
- dsa_etype_header_pos_tx

This series is just a resend as non-RFC of v1.
