Hi,
I've been playing with the 2.4.15-pre6-rmk1-hh1 kernel on my iPAQ, trying
to get it to make an FIR IRLan connection via a Tekram IRDocking station.
Everything appears to work correctly, it doesn't crash, it connects
without needing an irattach, /proc/net/irda/irlap reports a 4000000
connection. But I'm getting odd lags between frames which make its average
speed lower than the old serial SIR IrDA driver :-(.
To start the connection I did the following:
modprobe irlan
modprobe sa1100_ir
ifconfig irda0 up
echo 1 > /proc/sys/net/irda/discovery
pump -i irlan0
to demonstrate the problem I took an irdump (er...) whilst ping'ing the
local gateway. It looks all wrong with the sa1100_ir, either 800 ms or 0.
Does anyone know whats causing this?
Thanks
Matthew Horrobin
With sa1100_ir I get this:

Whereas a typical ping through the old SIR interface looks like this:
