[edk2-devel] [PATCH v3 2/5] NetworkPkg/HttpDxe: Decofigure Tcp6 before reconfiguring

[Oliver Steffen]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2720

Check if the state of the HTTP instance is HTTP_STATE_TCP_CONNECTED, or
HTTP_STATE_TCP_CLOSED and de-configure the Tcp6 instance before
configuring it again.
