Hi,
A quick update on the TODO.

I will resend a new version when 4.3-rc1 is out in order to fix any
possible conflict with linux/master. I already know that the netback
patch (#18) is conflicting with 1d5d48523900a4b0f25d6b52f1a93c84bd671186
"xen-netback: require fewer guest Rx slots when not using GSO".
If the 2 series above are completely acked/reviewed, I will fold them in
this series.
