But enabling IGB_LEGACY_TX disable multiqueue, right ?
And disabling NIC multiqueue feature have a big performance impact.

(In reply to Olivier Cochard from comment #2)
Multiqueue on igb is incompatible with ALTQ. When building a kernel with ALTQ
support, it must be disabled or queues may not be assigned to an igb interface.
The patch simply automates this dependency.
