WinDivert appears to block DHCP traffic to 255.255.255.255

[Matt Schulte]

Repro Steps:

1. Open up WireShark and filter on your primary interface for DHCP traffic
2. Run passthru.exe "udp and ((udp.DstPort == 67) or (udp.DstPort == 68))"
3. Run ipconfig /release
4. Notice the DHCP Release packet in WireShark
5. Run ipconfig /renew
6. Wait for the timeout. Notice no new DHCP packets are seen

I would expect the DHCP traffic to still be sent and show up in WireShark.
