Subject: [PATCH] RedfishPkg: RedfishDiscoverDxe: USB Redfish host
interface is not supported

[CAUTION: External Email]

Host Interface details are discribed by the SMBIOS Type 42 table.
The table is published by the RedfishHostInterfaceDxe driver.
That driver supports PCI-E and USB host interface types.
The table is consumed by the RedfishGetHostInterfaceProtocolData function
in the RedfishDiscoverDxe driver.
That function only supports PCI-E interface.
