Hello,
I am trying to use RTnet with my Intel 82575 NICs. I am using
xenomai-2.5-rc1, linux 2.6.29.1, and rtnet-0.9.11. I've tried rtnet's
e1000.ko, and e1000_new.ko drivers. Neither seems to recognize the device.
When I built my kernel I excluded support for "Intel(R) 82575/82576
PCI-Express Gigabit Ethernet," so the interface isn't shown via the standard
`ifconfig`.
It seems as though the device may not be supported. The new e1000 driver in
the RTnet experimental directory is based on the e1000-7.6.15.5 driver
provided by the Intel guys. I downloaded the original 7.6.15.5 version,
along with the latest, 8.0.6, and an additional driver, e1000e-0.5.18.3. I
did a quick search for "82575" in all of these drivers (including the RTnet
experimental e1000) and they reference the same thing:
./src/e1000_defines.h:112:/* Reserved (bits 4,5) in >= 82575 */
./src/e1000_defines.h:118:/* SDP 4/5 (bits 8,9) are reserved in >= 82575 */
./src/e1000_defines.h:145:/* IAME enable bit (27) was removed in >= 82575 */
Is there a quick and dirty hack I can try that will tie the "82575" device
ID to a driver of similar chipset? Is the problem that a PCI Express driver
is not written for this card? It looks as though, Mathias Koehrer did some
work to port the 7.6.15.5 e1000 driver to RTNet. Mathias, do you have time
to port latest e1000 driver(s) to RTnet? (Assuming that will fix my problem
:) Any advice to help me get up and running would be great.
Below is my `lspci` output for the device:
