[PATCH 06/61] sky2: pause parameter adjustment

[Chris Wright]

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

From: Stephen Hemminger <shemminger@xxxxxxxx>

The lower pause threshold set by the driver is too large and causes FIFO overruns.
Especially on laptops running at slower clock rates.
