Npcap 1.73

Installer, SDK, and symbols available from https://npcap.com/#download

• Fixed an issue causing "failed to set hardware filter to promiscuous mode"
  errors due to a new code path failing to return appropriate error codes. Fix
  by Guy Harris in PR #656.
  Fixes #628.

• Fixed an issue with WlanHelper causing "error 0x7b" since Npcap 1.70.Fix by
  Hauke Neitzel in PR #652.
  Fixes #649.

• Fixed an issue preventing capture handles from reattaching after NDIS stack
  pause operations, resulting in persistent ERROR_DEVICE_REMOVED (1617)
  errors. Fixes #627.

• Restored original behavior of timestamps in the default case,
  PCAP_TSTAMP_HOST_HIPREC_UNSYNCED/TIMESTAMPMODE_SINGLE_SYNCHRONIZATION.
  Since Npcap 0.9994, the timestamp was resynchronized after NDIS stack pause
  operations, which reduced timestamp drift from wall clock time but made it no
  longer monotonic, making packet interval calculations inaccurate. This
  restores the default behavior of WinPcap.

• Fixed an issue that prevented Npcap 1.71 and 1.72 from being completely
  removed on uninstall. A misconfigured npcap driver service had persisted.
  Fixes #657.

• Fixed an issue where applications using Npcap 1.20 or later DLLs with a Npcap
  1.00 driver would crash due to a stack buffer overrun when the driver returned
  too many bytes in response to a request for timestamp modes. Additionally,
  changed NPFInstall.exe to attempt to uninstall the Npcap NetCfg component
  prior to installation, in case an improperly-uninstalled component persists.

• Updated libpcap to 1.10.3.
