3c5dfe892d Few more minor if_vmx tweaks
- Allow the Rx/Tx queue sizes to be configured by tunables
 - Bail out earlier if the Tx queue unlikely has enough free
   descriptors to hold the frame
 - Cleanup some of the offloading capabilities handling

3c9657753e Couple minor if_vmx tweaks
- Use queue size fields from the Tx/Rx queues in various places
    instead of (currently the same values) from the softc.
  - Fix potential crash in detach if the attached failed to alloc
    queue memory.
  - Move the VMXNET3_MAX_RX_SEGS define to a better spot.
  - Tweak frame size calculation w.r.t. ETHER_ALIGN. This could be
    tweaked some more, or removed since it probably doesn't matter
    much for x86 (and the x86 class of machines this driver will
    be used on).
