Subject: staging: usbip: bugfix add number of packets for isochronous frames
From: Arjan Mels <[email protected]>
commit 1325f85fa49f57df034869de430f7c302ae23109 upstream.
The number_of_packets was not transmitted for RET_SUBMIT packets. The
linux client used the stored number_of_packet from the submitted
request. The windows userland client does not do this however and needs
to know the number_of_packets to determine the size of the transmission.
