Re: [RTnet-developers] Ethernet IP

[Glen W. <gl...@je...>]

I used select with a timeout. Select seems to work. It returns a positive number and a fdset.

It is accept which does not seem to work in taking off the top packets and send or write oopses the machine.

Accept does seem to work if I run it before select.

We can try the example but then I have to set up another machine.

Could any of thus be e1000 driver?
