Merge branch 'bpf-fib-mtu-check'
David Ahern says:
====================
Packets that exceed the egress MTU can not be forwarded in the fast path.
Add IPv4 and IPv6 MTU helpers that take a FIB lookup result (versus the
typical dst path) and add the calls to bpf_ipv{4,6}_fib_lookup.
v2
- add ip6_mtu_from_fib6 to ipv6_stub
- only call the new MTU helpers for fib lookups in XDP path; skb
path uses is_skb_forwardable to determine if the packet can be
sent via the egress device from the FIB lookup
====================
