+Subject: usb: host: xhci-rcar: Add XHCI_TRUST_TX_LENGTH quirk
+

+
+commit 40fc165304f0faaae78b761f8ee30b5d216b1850 upstream.
+
+When plugging BUFFALO LUA4-U3-AGT USB3.0 to Gigabit Ethernet LAN
+Adapter, warning messages filled up dmesg.
+
+[  101.098287] xhci-hcd ee000000.usb: WARN Successful completion on short TX for slot 1 ep 4: needs XHCI_TRUST_TX_LENGTH quirk?
+[  101.117463] xhci-hcd ee000000.usb: WARN Successful completion on short TX for slot 1 ep 4: needs XHCI_TRUST_TX_LENGTH quirk?
+[  101.136513] xhci-hcd ee000000.usb: WARN Successful completion on short TX for slot 1 ep 4: needs XHCI_TRUST_TX_LENGTH quirk?
+
+Adding the XHCI_TRUST_TX_LENGTH quirk resolves the issue.
