Subject: [PATCH bpf-next v2 0/3] net: skbuff: skb bitfield compaction - bpf

I'm trying to make more of the sk_buff bits optional.
Move the BPF-accessed bits a little - because they must
be at coding-time-constant offsets they must precede any
optional bit. While at it clean up the naming a bit.

v1: https://lore.kernel.org/all/20230308003159.441580-1-kuba@kernel.org/

Jakub Kicinski (3):
  net: skbuff: rename __pkt_vlan_present_offset to __mono_tc_offset
  net: skbuff: reorder bytes 2 and 3 of the bitfield
  net: skbuff: move the fields BPF cares about directly next to the
    offset marker
