[PATCH nf-next v2 0/6] net: netfilter: preliminary support for IPv4 over IPv6 and SIT flowtable offload

Introduce some preliminary changes needed to support flowtable offload
for IPv4 over IPv6 and SIT traffic.

---
Changes in v2:
- Fix dir configuration in nf_flow_offload_check_mtu() to compute tunnel
  MTU overhead.
- Link to v1: https://lore.kernel.org/r/20260901-nf-flowtable-sw-accel-ip6ip-sit-preliminary-v1-0-72e49be8c31f@oss.qualcomm.com (local)
