Dear all,
We are looking for a person who is able to update the rt_e1000e driver to make
it supporting the newer Intel NIC like 82574L, 82579LM, 82567V correctly under
the Xenomai 2.6.3 with a kernel at least 3.8.13 or newer. The problem is
following, while RTnet modules and drivers load correctly without any warnings,
NIC is not able to send ethernet frames for some random time. During that time,
RTnet stack report that is not able to transmit synchronization frame ("TDMA:
Failed to transmit sync
frame!"), the rt_e1000e driver reset device several times, and two leds
integrated with connector are not blinking. After a while, device start to
operate normally, sync frame are sending normally, and there is no further
issues. The main problem is, that we don't know when RTnet stack start to work,
so we have to wait unpredictable period of time. Also just after NIC start
sending sync frames, it has buffered several old ones, so it send them one
ofter another as fast as possible, what make
problem for our custom devices during synchronization phase. Currently, we
observe similar non acceptable behavior on following machines:
- Supermicro MBD-X9SPV-M4-3QE-O,
- Advantech PCM-3363D-1GS8A1E,
- Commel Mini-ITX Motherboard LV-67C.
with latest RTnet git version, Xenomai 2.6.3, kernel 3.8.13 and Ubuntu 12.04.
We expect that an involved person should prepare a patch which remove described
issues and applies cleanly to the latest RTnet git version. The patch should be
available for a community on the same license as RTnet stack. Patch will be
tested on listed devices.
We offer a contract to perform a specified task, one of the parties will be
