Subject: Issue with Micrel PCI Network Driver.
Date: Fri, 8 Feb 2013 17:17:08 -0600 [thread overview]
Message-ID: <51158774.8080405@novatechweb.com> (raw)
I am having an issue with one of the network interface drivers. The
driver in question is 'drivers/net/ethernet/micrel/ksz884x.c', the
driver for the Micrel-Kendin device 8841.
I am trying to get systemd to rename the three network interfaces in my
embedded atom system. I have one of the interfaces being renamed (an
Intel Corporation 82574L), but the two Micrel interfaces are not being
renamed. I traced this down to the driver not populating the
/sys/devices/pci* information. Instead it places the driver into
/sys/devices/virtual/net/.
Here are the details of the setup I am having the problem on:
# uname -a ; lspci ; lspci -t ; ls -l /sys/class/net/

This kernel is version 3.2.28 with the real-time patches applied.
If there isn't anyone available to resolve this issue I would be willing
to assist. I just do not have any experience writing Network Drivers or
PCI drivers. I have only written simple device drivers.
