Subject: [PATCH net-next 0/7] ipv4: Convert __fib_validate_source() and its
 callers to dscp_t.

This patch series continues to prepare users of ->flowi4_tos to a
future conversion of this field (__u8 to dscp_t). This time, we convert
__fib_validate_source() and its call chain.

The objective is to eventually make all users of ->flowi4_tos use a
dscp_t value. Making ->flowi4_tos a dscp_t field will help avoiding
regressions where ECN bits are erroneously interpreted as DSCP bits.

Guillaume Nault (7):
  ipv4: Convert ip_route_use_hint() to dscp_t.
  ipv4: Convert ip_mkroute_input() to dscp_t.
  ipv4: Convert __mkroute_input() to dscp_t.
  ipv4: Convert ip_route_input_mc() to dscp_t.
  ipv4: Convert ip_mc_validate_source() to dscp_t.
  ipv4: Convert fib_validate_source() to dscp_t.
  ipv4: Convert __fib_validate_source() to dscp_t.
