Sure; the scheme is simple, and is documented in dlpi(7P) and
dladm(1M).
The quick summary is that if you want access to (say) VLAN 7 on PPA 1
using driver "ce", you would attach to "ce7001." The formula is just:
VLAN * 1000 + PPA
Where "VLAN" is the tag number, and "PPA" is the ordinary device index
number (which normally starts with 0 for the first instance of a
driver installed).
The usual usage is like this:
echo 192.168.0.1/24 > /etc/hostname.ce5000
... to make VLAN 5 plumbed on ce0 at boot time with the indicated
address and mask.
