issues configuring vlan on top of aggr device

Hi misc@

I'm running openbsd 6.6 with latest patches running on a pair of hp dl 360
gen6 servers.

I'm attempting to configure an aggr0 device towards a cat 3650.

The aggr0 associates successfully with the switch, but I'm unable to run
vlans on top of it.

The configuration on openbsd is the following:
#ifconfig aggr0 create
#ifconfig aggr0 trunkport bnx0
#ifconfig aggr0 trunkport bnx1
#ifconfig vlan3800 create
#ifconfig vlan3800 vnetid 3800
#ifconfig vlan3800 parent aggr0
#ifconfig vlan3800 10.80.253.10/24
ifconfig: SIOCAIFADDR: No buffer space available.



This configuration works on my lab which is a -current box with em(4) nics
and an old catyst 2960 switch.


Thank you for your time,
Pedro Caetano
