Subject: [PATCH AUTOSEL 4.18 05/33] selftests: usbip: add wait after attach and before checking port status

From: "Shuah Khan (Samsung OSG)" <shuah@...nel.org>

[ Upstream commit 4b0aaacee51eb6592a03fdefd5ce97558518e291 ]

Add sleep between attach and "usbip port" check to make sure status is
updated. Running attach and query back shows incorrect status.
