Net.bcm57xx wouldnt work in GigE mode

Using QNX on Dell PowerEdge 860. Can't get Net.bcm57xx driver to set 
ethernet to 1000 Mb, best it will do is 100 Mb FD.
Anyone have a work around ?

RE: Net.bcm57xx wouldnt work in GigE mode

Please try the attached version and let me know if it solves the
problem. If not, I will need the output from 'show_pci -v'.

Thanks.

Net.bcm57xx  -I0 -l1 -M &

Output on screen (handcopied...sorry)
PCI-EXpress card (4101)!

Please try the attached debug version of the driver and let me know what
it displays on the screen. It should either display "Set Advert xx" or
"No GB advert". Also, if you force the speed and duplex, does it then
work at gigabit speed?

Thanks, Hugh.

Re: RE: RE: Net.bcm57xx wouldnt work in GigE mode

Hugh

Says
Set advert 300
an enable

Also went to 1000 bT FD by itself
Both broadcomm ethernet ports set correctly
I have 4 machines, doing flood ping of 1500 bytes over the GigE from 3 machines to 1 common machine resulted in 15000 
packets / sec xmit and recv
for 180 Mb/sec xmit and rcvr rates

Dave,

So are you saying that the driver is working correctly? If so, I will
removed the debug and send you a new driver.

Hugh,

Do have a question
What does warning "buffer stuck at 248!!" mean ?

RE: RE: RE: RE: Net.bcm57xx wouldnt work in GigE mode

There is a bug on the Broadcom chips where the receive buffer sticks
only once after initialization and has to be un-stuck! The message is
just a warning. Here is the non-debug driver.
