Yes, this is what I would recommend. Although it's not as simple as
turning it on, you actually need to patch the Kconfig as in this mail:
http://www.spinics.net/lists/netdev/msg325844.html such that it comes on
by itself.

I don't think so, those were used in that thread to demonstrate that the
issue exited even on native -- i.e. not under Xen
If you could file your results into the Debian BTW[0], i.e. by running
"reportbug <linux-image-pkg-name>" then that would be useful to help get
it fixed in a future update.
