Support for multiple ethernet ports

[Alex Holeczy]

RTEMS Version : 4.5.0
Processor     : MIPS
network device: National Semiconductor dp83815

Is there a way to search the Rtems-users archives to see if the questions
I have about RTEMS have all ready been answers?


It appears from reading the RTEMS network supplement that RTEMS can
supports multiple Ethernet ports.  For my application, I would like to
configure RTEMS to support 3 Ethernet ports.

I have successfully configured RTEMS to use a single Ethernet port.  When
I configure RTEMS to use two ports, part way through the initialization of
the second port I get the following error:

    Can't set eth2 address: File exists

This error message is in rtems_glue.c at approximately line 828.  The call
to ioctl (s, SIOCSIFADDR, &ifreq) returns with a failure.

Since RTEMS seems to support multiple Ethernet port, I am assuming that I
have not correctly configured the building of RTEMS.  How do I configure
RTEMS to support 3 Ethernet ports?


TIA
Alex
