ix: report isc_pause_frames during stat update

[jacob.e.keller_intel.com]

Summary

Notify the iflib stack of whether we received any pause frames during
the timer window. This allows the stack to avoid reporting a Tx hang due
to the device being paused.

this comes from IXGBE_LXOFFTXC.. Isn't that a counter of the pause frames that we have sent? I would think you'd want to use IXGBE_LXOFFRXC, which I think counts the pause frames we've received..?

Yea, I think you're right.
