rt2x00 doesn't "own" Linux Ralink support, ditto for rt2800 drivers.

This is not how things work here, sorry.

If you are not willing to stand behind your own patches, how do you expect
others to trust your judgment?

I meant rt2800 support specifically, sorry if this was not clear.

The work on rt2800 drivers was started in the beginning of 2008 and after
few months you were already behind deadlines that you had set yourself:

During almost two years rt2x00 project didn't manage to produce working
support for rt2800.. in the meantime the world has moved on and we have
another chipset generation (rt30x0) to worry about, and also rt33xx one
on the horizon..

Nope, it just adds needles development/maintenance burden since it will
make people lose fixes already applied to the working code, please see my
other mail.

The right time was two years ago when you were starting working on those
drivers. IOW It shouldn't have happened in the first place.

I also have serious questions about transparency of the process and cannot
understand why it takes so long for the code to be pushed upstream.

commit 1761631 -- obvious bugfix and I'm pretty sure I've seen it in rt2x00
tree back in September (you're re-basing rt2x00 tree at random moments so it
is impossible to track the status of patches that you are handling).

rt2800pci patch itself has been getting dust in your tree since at least
April (it hasn't received any bigger updates since then)..

Please see my other mail.

The knowledge is all in your local copy of linux-next (I don't memorize
things like chipset initialization sequences) and in the review comments
that you have happily dismissed.
