Subject: usbip: Fix USB device hang due to wrong enabling of scatter-gather
From: Yuyang Du <yuyang.du@intel.com>
commit 770b2edece42fa55bbe7d4cbe53347a07b8968d4 upstream.
The previous USB3 SuperSpeed enabling patches mistakenly enabled
URB scatter-gather chaining, which is actually not supported by
the VHCI HCD. This patch fixes that.
