bpf: Remove MTU check in __bpf_skb_max_len
bpf: fix bpf_fib_lookup helper MTU check for SKB ctx
bpf: bpf_fib_lookup return MTU value as output when looked up
bpf: add BPF-helper for MTU checking
bpf: drop MTU check when doing TC-BPF redirect to ingress
- bpf: make it possible to identify BPF redirected SKBs
selftests/bpf: use bpf_check_mtu in selftest test_cls_redirect
bpf/selftests: tests using bpf_check_mtu BPF-helper
