In pfSense the driver has been modified to compile a hybrid mode.
Meaning have activated both LEGACY and new transmit queue model.

It works correctly and avoids the problems of recompiling with ALTQ.
It also solves the  problem on having performance impacts when ALTQ is not
in use.

There are even some drivers in the tree that do this by default already.

>From my analysis there should not be an LEGACY define but just mask all of
this behind ALTQ definition if needed.
