new device/bus stuff

[Julian Elischer]

Is there a howto on how to convert drivers from the old to new
form?

for example if_sr.c no longer shows up (or is even probed) in
4.0-stable. I've looked here and there but I can't figure out if there
is some ISA_SHIM option needed (it's not in LINT if so).

There seemes to be lotsa complicated man pages but I haven't found
a brief "here's what you probably need to do" doc..

I'm looking for something that doesn't require rewriting the whole
thing..

Hmmm, I would be interested too. I would like to convert the if_ar
and if_sr drivers, but they are not as straight foward as the "normal"
drivers, because a chip can have two channels and a card can have two
chips. Or maybe I'm just thinking too complicated about it?

Oops, I forgot about the if_sr driver. Just change the line

struct  isa_driver srdriver = {srprobe, srattach_isa, "src"};
to
struct  isa_driver srdriver = {srprobe, srattach_isa, "sr"};

I'll do it when I remove all the frame relay hooks out of the driver.
It has never been used outside SDL and they are not interested in
make it available. If anyone want to use frame relay they can use
the netgraph stuff.

Not completely.  Just look at ep or ed drivers and do it the same way
:-)
