Avoid initializing loopback capture-related functions and processing packets
as soon as an adapter is opened. This will improve performance since adapters

Fix a crash in NPFInstall.exe when terminating processes which are using
Npcap resources. This could lead to failed installations and message windows
about "A LWF & WFP driver installation tool has stopped working."
Update Npcap from NDIS 6.10 to NDIS 6.20, which limits its compatibility to
Windows 7 and higher. Closes #167.
Fix a bug in Npcap 0.9991 which prevented packets from being captured until a
BPF filter had been set. Fixes #168 (migrated
Allow capture statistics and captured packets remaining in the buffer to be
retrieved when an adapter is removed. Fixes nmap/nmap#2036.

Get-NetAdapterPowershell cmdlet in
the DiagReport tool. Fixes nmap/nmap#611.
