vlan tag   
The QNX 6.4.0 doc says that the argument for ifconfig vlan is a 16 bit number but the 6.5.0 says it's a 12 bit number.  
Does that mean that with 6.5.0 it's not possible to set the PCP ( Priority Code Point )

Re: vlan tag   
Support for setting the PCP field was added in after the initial release of 6.5.0. If you are up to date on your PSPs, 
the use message on ifconfig should mention:

vlanprio priority
                     If the interface is a vlan(4) pseudo-interface, set the
                     VLAN priority to priority. This is a number 0-7, used
                     to create an 802.1Q VLAN header for packets sent from the
                     vlan(4) interface.

Re: RE: vlan tag   
Yes, this was added post 6.5.0 SP1.

A PSP is a Priority Support Package, and this capability was added in PSP3078 (io-pkt) and PSP3079 (ifconfig). Later 
PSPs containing these binaries will also support this functionality so you should use the latest version.
