Uh, this is prone to descend into build trees and edit random crap. I
used
$ sed -i -e ... `git-ls-tree -r HEAD | awk '$2 == "blob" { print $4 }'`
to verify this commit. Differences noted inline.

I guess this is the "-e 's/netdev->kind/netdev->type/g'" you deleted
from Zoltán's commit message.

I suspect this explains most of the differences between the sed script's
results and the actual patch. Would it be possible to split the patch
into a mechanical and a manual part, for easier review? If not, could
explain your manual edits in more detail?

sed turns this into
dump = netdev->u.dump.data;
Is this part of the manual changes? More of the same below.
