Adding Compilation option for VTNET Driver

Hello,

i hope this is the right mailing list. I wanted to add an compilation Option, and small change to the VTNET (VirtIO Networking) Driver, and wanted to know if this is fine to submit. The Problem is, that i need an ALTQ capable kernel, and that the VTNET Interfaces are multiqueue capable. This isn't possible, as the source for the VTNET Driver contains this check:

"""
#ifdef ALTQ
#define VTNET_LEGACY_TX
#endif
"""

Which causes it to not be Multiqueue capable, and instead being ALTQ capable. I would like to add an option, called "VTNET_NO_ALTQ" or "VTNET_FORCE_MULTIQUEUE", and modify the check above to be:

"""
#if defined ALTQ && ! defined VTNET_NO_ALTQ
#define VTNET_LEGACY_TX
#endif
"""

So that it is possible, to have a Kernel with ALTQ, but that the VTNET Driver is not ALTQ capable, and instead Multiqueue capable.

Thanks.
