We want to no longer rely on RTNL for "ip link show" command.

This is a long road, this series takes care of some parts.

Eric Dumazet (8):
  rtnetlink: do not depend on RTNL for IFLA_QDISC output
  rtnetlink: do not depend on RTNL for IFLA_IFNAME output
  rtnetlink: do not depend on RTNL for IFLA_TXQLEN output
  net: write once on dev->allmulti and dev->promiscuity
  rtnetlink: do not depend on RTNL for many attributes
  rtnetlink: do not depend on RTNL in rtnl_fill_proto_down()
  rtnetlink: do not depend on RTNL in rtnl_xdp_prog_skb()
  rtnetlink: allow rtnl_fill_link_netnsid() to run under RCU protection
