Basic NMR integration for MsQuic (#3961)
Browse files Browse the repository at this point in the history
The PR adds an NMR interface (NMR provider) for kernel mode msquic. The MsQuic provide only exposes 2 interfaces, MsQuicOpenVersion and MsQuicClose, which are the same as what are exposed in msquic.sys. This PR does not remove the exports.
