Vladimir Oltean says:

====================
Remove skb_mac_header() dependency in DSA xmit path

Eric started working on removing skb_mac_header() assumptions from the
networking xmit path, and I offered to help for DSA:
https://lore.kernel.org/netdev/20230321164519.1286357-1-edumazet@google.com/

The majority of this patch set is a straightforward replacement of
skb_mac_header() with skb->data (hidden either behind skb_eth_hdr(), or
behind skb_vlan_eth_hdr()). The only patch which is more "interesting"
is 9/9.

Another potential caller of __skb_vlan_pop() on xmit (and therefore
also of skb_mac_header()) is tcf_vlan_act(), but I haven't had the time
to investigate that (enough to submit changes other than what's here).

v1->v2:
- 09/09: document the vlan_tci argument of vlan_remove_tag() in the kdoc

v1 at:
