net: addr_list: add exclusive dev_uc_add and dev_mc_add
This adds a dev_uc_add_excl() and dev_mc_add_excl() calls similar to the original dev_{uc|mc}_add() except it sets the global bit and returns -EEXIST for duplicat entires. This is useful for drivers that support SR-IOV, macvlan devices and any other devices that need to manage the unicast and multicast lists. v2: fix typo UNICAST should be MULTICAST in dev_mc_add_excl() CC: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.
