Simply nobody finished it up yet.

I did the last tls-maxphys sync. It will need at least one resync,
since more stuff moved around (i.e. wd(4) was converted to dksubr
since then).

I want to eliminate some duplicated code in PCI-IDE drivers before the
merge. Other than that, I don't see any other blockers for the merge.

Of course, it requires proper round of testing before it could be
really considered merge-worthy.

As others noted, the performance benefit of tls-maxphys is likely to
be small. It however removes artificial limits in the stack, unlocking
new opportunities for further development, so it's both necessary and
good to do nevertheless.
