I hope this mailing list is not specifically just for UNIX dev.
I have a custom OS (not based on any existing OS) that has a 82574L driver.
It's very minimal but it's capable of RX and TX at gigabit speeds with UDP.
I got a new box with an 82576 NIC and booted up my OS on it. TX worked out
of the box but RX is having problems. Basically I poll for RX descriptor
flags until DD is set. Descriptor done simply is never getting set on the
82576 machine.
Anyone have an idea of what problem I may be having? Is there some
filtering that is done by default? I run with unicast promiscuous and
multicast promiscuous as well as accept broadcast packets. I'm only doing a
single queue, and I reset the device fully in my OS.
