David Vrabel 49d9991a18 xen-netback: unref frags when handling a from-guest skb with a frag list ... Every time a VIF is destroyed up to 256 pages may be leaked if packets with more than MAX_SKB_FRAGS frags were transmitted from the guest. Even worse, if another user of ballooned pages allocated one of these ballooned pages it would not handle the unexpectedly >1 page count (e.g., gntdev would deadlock when unmapping a grant because the page count would never reach 1). When handling a from-guest skb with a frag list, unref the frags before releasing them so they are freed correctly when the VIF is destroyed.
