Guillaume Nault says:

====================
ipv4: Remove RT_CONN_FLAGS() calls in flowi4_init_output().

Remove a few RT_CONN_FLAGS() calls used inside flowi4_init_output().
These users can be easily converted to set the scope properly, instead
of overloading the tos parameter with scope information as done by
RT_CONN_FLAGS().

The objective is to eventually remove RT_CONN_FLAGS() entirely, which
will then allow to also remove RTO_ONLINK and to finally convert
->flowi4_tos to dscp_t.
