usb networking mac address changes on each boot

To connect two Neo's to the same host via usb networking, you need to give them
separate subnets (or at least separate IPs on the same subnet). To do this
deterministically, you need to know the MAC address of the Neo. Unfortunately,
that seems to change randomly on each boot.

Looks like it should be possible on the kernel cmdline:

module_param(dev_addr, charp, S_IRUGO);
MODULE_PARM_DESC(dev_addr, "Device Ethernet Address");
module_param(host_addr, charp, S_IRUGO);
MODULE_PARM_DESC(host_addr, "Host Ethernet Address");

(yet to be tested, will close this bug if it works)

We are aware of that issue, and are planning to have fixed, official MAC
addresses allocated for the usb networking interface for GTA02.

  • Status changed from new to closed
  • Resolution set to duplicate

This is in fact a close relative to #1023. So the same work-around
applies, and also the long-term solution is the same.

* This bug has been marked as a duplicate of 1023 *
