Problem Description:	

	The new SW Version IOS 11.1(17)CC which was loaded into Vienna-EBS1
	this morning appears to have a bug in the driver code for (at least)
	PA-8E interfaces.  This intermittently leads to significant
	performance degradation on those interfaces (rtts of >1000ms, high
	drop-rate though by far not fully loaded).  We haven't found a
	workaround yet, therefore we need to step back to the previously
	running version.
