[edk2-devel] [PATCH V3] RedfishPkg: RedfishDiscoverDxe: USB Redfish host interface is not supported

[Igor Kulchytskyy via groups.io]

Host Interface details are described 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.
The function only supports PCI-E host interface type.
