Re: [PATCH,RFC] Re: r8169 driver problem with RTL8110SB chip (on iop3xx ARM board)

Lennert Buytenhek [off-list ref] :

I suspect it's a chip bug.  I rechecked with I/O space, and that works
okay, so this artifact (bug) only manifests itself when you do the upper
write in MMIO space.

Are there any plans to switch r8169 to the iomap API?  Would you take
a patch if I'd write one?

Given the current state of the r8169 driver, I do not see a lot of
benefit from the iomap() API in itself.

It could make the switch to I/O read/write easier for strange bugs
like your but I have an epidermic defiance against I/O ops (much too 
synchronizing for me: people forget that MMIO will post). I may
change my mind if bugs start poping up like mushrooms but we are
hopefully not there yet.

An ordered write with a big sign in front of it to comment the issue
is good enough for me.

Don't hesitate to protest if you think that I need a clue.
