JIRA: https://issues.redhat.com/browse/RHEL-56984 commit 8f36b3b4e1b58dca7d05e1579019230437e55d43 Author: Shuah Khan <skhan@linuxfoundation.org> Date: Tue Aug 23 18:24:56 2022 -0600 usbip: add USBIP_URB_* URB transfer flags USBIP driver packs URB transfer flags in network packets that are exchanged between Server (usbip_host) and Client (vhci_hcd). URB_* flags are internal to kernel and could change. Where as USBIP URB flags exchanged in network packets are USBIP user API must not change. Add USBIP_URB* flags to make this an explicit API and change the client and server to map them. Details as follows: Client tx path (USBIP_CMD_SUBMIT): - Maps URB_* to USBIP_URB_* when it sends USBIP_CMD_SUBMIT packet. Server rx path (USBIP_CMD_SUBMIT): - Maps USBIP_URB_* to URB_* when it receives USBIP_CMD_SUBMIT packet. Flags aren't included in USBIP_CMD_UNLINK and USBIP_RET_SUBMIT packets and no special handling is needed for them in the following cases: - Server rx path (USBIP_CMD_UNLINK) - Client rx path & Server tx path (USBIP_RET_SUBMIT) Update protocol documentation to reflect the change.
