Network VLAN Device Driver

[Michael J. Siers]

Hi All,
I am doing a little testing with the latest version snapshot of the 
RTEMS code
on an i386 pc.  I have one network driver (fxp0) but I would like to have it
setup to handle two different IP addresses.  This cabability is 
available in *BSD
by setting up a IEEE 802.1Q VLAN device support in the kernel and using the
ifconfig command with the different vlan parameters. This adds a vlan0 
interface
to the system.

Has anyhow done this with RTEMS?  I searched through the RTEMS source
tree and I do not see any reference to the VLAN cabability.  I am 
guessing I will
have to update some network source files and add a new network driver 
if_vlan.
What version of the FreeBSD TCP/IP stack is being used by RTEMS?

Any information would be greatly appreciated.
