hyperv/hn: Partly rework transmission path
- Avoid unnecessary malloc/free on transmission path.
- busdma(9)-fy transmission path.
- Properly handle IFF_DRV_OACTIVE. This should fix the network
stalls reported by many.
- Properly setup TSO parameters.
- Properly handle bpf(4) tapping. This 5 times the performance
during TCP sending test, when there is one bpf(4) attached.
- Allow size of chimney sending be tuned on a running system.
Default value still needs more test to determine.
