ppp interfaces throw error when adding to team #21

Open TJC opened 8 years ago

TJC commented 8 years ago

Attempting to add a ppp interface results in errors:

# ifconfig ppp0 down
# teamdctl team0 port add ppp0
libteamdctl: cli_usock_process_msg: usock: Error message received: "PortAddFail"
libteamdctl: cli_usock_process_msg: usock: Error message content: "Failed to add port."
command call failed (Invalid argument)
#

syslog reports the following:

As far as libteam goes, the error is returned from rtnl_link_enslave_ifindex() in team_port_add()

I also tested this on kernel 4.2.5 and it presents the same errors.
