====================
ice: split ice_virtchnl.c git-blame friendly way
Przemek Kitszel says:
Split ice_virtchnl.c into two more files (+headers), in a way
that git-blame works better.
Then move virtchnl files into a new subdir.
No logic changes.
I have developed (or discovered ;)) how to split a file in a way that
both old and new are nice in terms of git-blame
There was not much discussion on [RFC], so I would like to propose
to go forward with this approach.
There are more commits needed to have it nice, so it forms a git-log vs
git-blame tradeoff, but (after the brief moment that this is on the top)
we spend orders of magnitude more time looking at the blame output (and
commit messages linked from that) - so I find it much better to see
actual logic changes instead of "move xx to yy" stuff (typical for
"squashed/single-commit splits").
Cherry-picks/rebases work the same with this method as with simple
"squashed/single-commit" approach (literally all commits squashed into
one (to have better git-log, but shitty git-blame output).
Rationale for the split itself is, as usual, "file is big and we want to
extend it".

ice: finish virtchnl.c split into rss.c
ice: extract virt/rss.c: cleanup - p2
ice: extract virt/rss.c: cleanup - p1
ice: split RSS stuff out of virtchnl.c - copy back
ice: split RSS stuff out of virtchnl.c - tmp rename
ice: finish virtchnl.c split into queues.c
ice: extract virt/queues.c: cleanup - p3
ice: extract virt/queues.c: cleanup - p2
ice: extract virt/queues.c: cleanup - p1
ice: split queue stuff out of virtchnl.c - copy back
ice: split queue stuff out of virtchnl.c - tmp rename
ice: add virt/ and move ice_virtchnl* files there
