Hi Antonio,
The issue is I used Arne's working dco branch, it fails to register
AF_NETLINK group.
Old code like:
int ret = nl_socket_add_memberships(dco->nl_sock, dco->ovpn_dco_mcast_id,
RTNLGRP_LINK, RTNLGRP_NOTIFY,
RTNLGRP_NONE);
I see Arne just pushed new code:
int ret = nl_socket_add_membership(dco->nl_sock, dco->ovpn_dco_mcast_id);
Had a quick test, it's fine. I'm not sure why the old code in my X86-64 PC
is OK while it
doesn't work in this MIPS64 router. Maybe it's not related with the kernel
version.
Tony
