Specifically:
CONFIG_NET_TEAM=m
CONFIG_NET_TEAM_MODE_BROADCAST=m
CONFIG_NET_TEAM_MODE_ROUNDROBIN=m
CONFIG_NET_TEAM_MODE_RANDOM=m
CONFIG_NET_TEAM_MODE_ACTIVEBACKUP=m
CONFIG_NET_TEAM_MODE_LOADBALANCE=m
I built just the modules against the stock 4.9.39-2 kernel and they built and are working fine. Is there any reason not to enable these? (I will do a pull req, I guess, if there is no reason not to).
