Merge branch 'ipv4-handle-tos-and-scope-properly-for-icmp-redirects-and-pmtu-updates'
Guillaume Nault says:
====================
ipv4: Handle TOS and scope properly for ICMP redirects and PMTU updates
ICMPv4 PMTU and redirect handlers didn't properly initialise the
struct flowi4 they used for route lookups:
* ECN bits sometimes weren't cleared from ->flowi4_tos.
* The RTO_ONLINK flag wasn't taken into account for ->flowi4_scope.
In some special cases, this resulted in ICMP redirects and PMTU updates
not being taken into account because fib_lookup() couldn't retrieve the
correct route.
