A bit of documentation for the hardware flow control API would help as
well. The API might be fine and dandy, but if all you have is a couple of
modified drivers -- some of which are not even in the standard kernel --
then you can bet not many driver writers are going to even be aware of it,
let alone care to implement it.

For instance: in 2.2.19, the help text for CONFIG_NET_HW_FLOWCONTROL says
only tulip supports it in the standard kernel -- yet I can't find that
support anywhere in drivers/net/*.c, tulip.c included.

In 2.4.10 tulip finally supports it (and I'm definitely going to take a
closer look), but that's about it. And tulip is definitely the wrong
example to pick if you want a nice and clean model for your driver.
