Subject: [PATCH net-next v2 0/4] net/ipv6: RFC6724 rule 5.5 preparations

Hi all,

let's try this again, this time without accidentally shadowing the 'err'
variable.  Sigh.  (Apologies for the immediate v2.)

following 4 patches are preparations for RFC6724 (IPv6 source address
selection) rule 5.5, which says "prefer addresses announced by the
router you're using".  The changes here just pass down the route into
the source address selection code, it's not used for anything yet.
(Any change of behavior from these patches is a mistake on my end.)

Cheers,

David

  net/ipv6: flatten ip6_route_get_saddr
  net/ipv6: create ipv6_fl_get_saddr
  net/ipv6: use ipv6_fl_get_saddr in output
  net/ipv6: drop ip6_route_get_saddr
