All of those are retained by default here in this set. There are 0
changes to the if_bonding.h uapi header, module parameters with 'port'
in them have duplicates with the old terminology included, and all
sysfs file names are duplicated (or aliased) as well. The
documentation was updated to point to the new names, but the old ones
still exist across the board, there should be no userspace breakage
here. (My lnst bonding tests actually fall flat currently if the old
names are gone).
