[PATCH] ixgbe: Report PAUSE flags to ethtool

[Esa-Pekka Pyokkimies <esa-pekka.pyokkimies@stonesoft.com>]

Hello!

I noticed that ixgbe driver doesn't report SUPPORTED_Pause and
ADVERTISED_Pause flags to ethtool. This means that ethtool
always reports:
	Supported pause frame use: No
	Advertised pause frame use: No
I added reporting for capabilities and advertising.
I tested it with our ixgbe card and latest ethtool
   from git repo. I also need to add capability to
change advertising parameters with "ethtool -s advertise %x",
but will send in a different patch if this patch looks ok.
