Subject: [PATCH 3.16.y-ckt 068/126] xen-netback: fixing the propagation of the transmit shaper timeout

3.16.7-ckt5 -stable review patch.  If anyone has any objections, please let me know.

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

From: "Palik, Imre" <imrep@...zon.de>

commit 07ff890daeda31cf23173865edf50bcb03e100c3 upstream.

Since e9ce7cb6b107 ("xen-netback: Factor queue-specific data into queue struct"),
the transimt shaper timeout is always set to 0.  The value the user sets via
xenbus is never propagated to the transmit shaper.

This patch fixes the issue.
