It took me a bit to figure out why there is a separate command
code but no special handler for the compat structure, aside from
being in the wrong file it does look correct.

We could actually drop the #ifdef here as well, or moving into
the existing #ifdef.

It should get merged through the netdev tree, as Chas does not have
a separate git tree for drivers/atm.

I don't know what happened to the rest of the series, but if there are
additional patches that got lost, merging them all through either the
asm-generic or the mm tree would work as well.

Any chance you or Palmer could rebase the series to 6.2-rc and
see what remains?
