X-Git-Tag: firefly_0821_release~176^2~802^2~1444 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b914b4944902d489226a5b465908403505723b9a;p=firefly-linux-kernel-4.4.55.git staging: vt6656: don't stop TX queue unless buffer full. Presently the TX buffer stops while filling the buffer and urb. However, this does not make use of the available buffer space, it also lags the speed of the TX troughtput. Only stop the queue when the buffer becomes full. The URB complete will start the queue again when a buffer and URB is available.
