It sounds really odd-ball to me, too.  Plus, it would require touching 
all the existing GLDv3 driver.  Yech.  Far, far better to add 
MAC_CAPAB_NATIVEVLAN (or even better, MAC_CAPAB_VLAN_PPA, which more 
accurately describes  the feature.)

Of course, IMO, this is really, really weird, because *today* Nemo 
drivers are totally ignorant of PPAs, as such.  I'm not sure how a Nemo 
driver with this feature would act... what causes a VLAN PPA attach to 
happen.  But there is lot about clearview that I don't completely 
understand.
