Michal,
although the above is true i'd say it's a bit of an overkill:
RX VLAN stripping is configured in a function level, so keeping it in a per 
queue level is not needed. 

The problem u were trying to resolve (and u resolved it) was to separate the 
RX_VLAN_ENABLED flag semantics into two: requested feature and HW configured 
feature in order to further check the second in the fast path, while setting 
the first one in the set_features(). Then the second lag is updated according 
to the first one during the loading of the function (bnx2x_nic_load()).

Therefore it would be enough to just add those two flags in the function (bp) 
level keeping the rest of your patch as it is. This would also cancel the need 
for a patch 6.

Thanks,
vlad
