Hi,
This set of patches change the e1000 migration code to make
it easier to keep with compatibility with older versions in backwards
migration.
I think the first 3 patches are fairly uncontrovercial and I would like
them for 2.12; it would be nice to have the lot since changing them
after we've shipped is much more difficult.
v2
Ed and Paolo answered my question that I asked in the cover letter;
and I think I've followed the advice - although my testing has been
very light. The new patches do two things:
a) When we receive a stream without the subsection we duplicate the
received pops state into both props and tso_props.
b) When we send without the subsection we decide which set to send
in the main part of the state based on which state was last changed.

e1000: Convert v3 fields to subsection
e1000: Dupe offload data on reading old stream
e1000: wire new subsection to property
e1000: Migrate props via a temporary structure
e1000: Choose which set of props to migrate
e1000: Old machine types, turn new subsection off
