Subject: [PATCH net-next 06/14] bridge: mcast: Expose __br_multicast_del_group_src()
Expose __br_multicast_del_group_src() which is symmetric to
br_multicast_new_group_src() and does not remove the installed {S, G}
forwarding entry, unlike br_multicast_del_group_src().
The function will be used in the error path when user space was able to
add a new source entry, but failed to install a corresponding forwarding
entry.
