Subject: [PATCH 3.12 034/133] rtlwifi: Increase the RX queue length for USB drivers

3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@...inger.net>

commit dc6405712268fe514d3dd89aa936c4397b0871b9 upstream.

The current number of RX buffers queued is 32, which is too small under
heavy load. That number is doubled.
