Subject: [PATCH bpf 0/2] bpf: udp: A few reuseport's bpf_prog for udp lookup

This series has fixes when running reuseport's bpf_prog for udp lookup.
If there is reuseport's bpf_prog, the common issue is the reuseport code
path expects skb->data pointing to the transport header (udphdr here).
A couple of commits broke this expectation.  The issue is specific
to running bpf_prog, so bpf tag is used for this series.

Please refer to the individual commit message for details.

Martin KaFai Lau (2):
  bpf: udp: ipv6: Avoid running reuseport's bpf_prog from __udp6_lib_err
  bpf: udp: Avoid calling reuseport's bpf_prog from udp_gro
