Improve compatibility with WinPcap's behavior regarding injected traffic.
WinPcap uses inefficient loopback to capture all outbound traffic, but allows
PacketSetLoopbackBehavior()to avoid this for injected traffic. Because of
Npcap's more efficient design, injected traffic was never looped back up to
protocol drivers, causing problems for some users who relied on this behavior.
Now, injected traffic follows the same path as with WinPcap, though ordinary
traffic is unaffected. For highest efficiency without loopback, use
PacketSetLoopbackBehavior(PACKET_DISABLE_LOOPBACK). Fixes #1343,
#1929, and GNS3/gns3-gui#2936
No longer honor
This packet filter causes all local traffic to be routed through an unoptimized
loopback path within NDIS, which was necessary to capture outgoing traffic in
WinPcap but is no longer needed in Npcap. Instead, this value will be treated as
NDIS_PACKET_TYPE_DIRECTED | NDIS_PACKET_TYPE_MULTICAST | NDIS_PACKET_TYPE_BROADCAST.
Fix a bug that caused
TIMESTAMPMODE_QUERYSYSTEMTIME_PRECISEto fall back to

Installer will now install an intermediate CA cert that was missing from some
systems, which is needed to verify the driver's digital signature. Only
affects Windows versions prior to Windows 10.
