Beagleboard-xm chooses a new IP address on each boot

[BernardB]

The smsc95xx driver used on the Beagleboard-XM currently generates a new random MAC address every time the interface is brought up. This makes it impossible to override using the standard `ifconfig hw ether` approach or through /etc/network/interface.

As a result, the board gets a new IP address on each boot from DHCP, and confuses dynamic DNS setups linked to DHCP.

There is an upstreamed patch (merged in 2.6.37-rc1) at http://marc.info/?l=linux-omap&m=128744421925804&w=2 which enables the user to set their MAC address using the standard tools. Please consider pulling this into the stable maverick omap3 kernel.

(Bug #673504 was also filed for the omap4 kernel under linux-ti-omap4 - solution is the same for both).

[Ricardo Salveti (rsalveti)]

This patch fix the issue of regenerating the mac address on every ifdown/ifup when you don't explicit set it up at the kernel. The fix makes it consistent with other drivers, and let people set the proper mac address with current known methods.

As it's also upstream, I don't see a reason not to take it. Will generate a new kernel deb file with the patch included, so we can test it before sending the SRU.

[Ricardo Salveti (rsalveti)]

Kernel compiled with the pointed patch:
http://people.canonical.com/~rsalveti/maverick/kernel/linux-image-2.6.35-23-omap_2.6.35-23.37rsalveti1_armel.deb

Please test and let us know if it did work for you. Will then forward to the kernel team with a SRU.

Tested on beagleboard-xm here and worked beautifully.

Thank you!

Accepted linux-ti-omap4 into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Oliver Grawert (ogra)]

this bug is not a duplicate of the omap4 one (different kernel tree and package)

[Martin Pitt (pitti)]
