From: Heng Luo @ 2021-07-22 7:38 UTC (permalink / raw)
To: devel; +Cc: Maciej Rabeda, Jiaxin Wu, Siyuan Fu
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3496
Add new EDKII_HTTP_CALLBACK_PROTOCOL in NetworkPkg,
Send HTTP Events via EDKII_HTTP_CALLBACK_PROTOCOL
when Dns/ConnectTcp/TlsConnectSession/InitSession
occurs.
