multi_client: Limit reached, cannot add more links

[alfs]

I was trying to add a wlan interface to a monroe node, and didn't get an address. Got this in the syslog:

Dec  5 16:04:55 Monroe000db93f812c kernel: [254789.257958] wlan0:
associated
Dec  5 16:04:55 Monroe000db93f812c multi_client: Interface wlan0 (5) is
RUNNING, length 32
Dec  5 16:04:55 Monroe000db93f812c multi_client: Limit reached, cannot
add more links

These are the links on the system:
