Subject: [PATCHv2 net 0/2] net: fix nsna_ping not working in team

Completely disabling ipv6 addrconf is too harsh to team driver,
as nsna_ping link-watch still needs it. The 1st patch is to fix
it by only preventing DAD and RS sending for it, and 2nd patch
is to add a selftest for all factors that may prevent DAD and
RS sending including the team/bond slave ports.

v1->v2:
  - no need to check IFF_NO_ADDRCONF addrconf_dad_begin(), see
    Patch 1.
  - add a selftest for DAD and RS as David Ahern suggested, see
    Patch 2.

Xin Long (2):
  ipv6: prevent only DAD and RS sending for IFF_NO_ADDRCONF
  kselftest: add a selftest for ipv6 dad and rs sending
