This is continuation of "Significant difference between 2.6.34 and
2.6.39?" (http://lists.infradead.org/pipermail/libertas-dev/2011-August/003671.html)
This includes *debug information*.
Machine: Gumstix Overo Fire COM (ARM Cortex-A8), Wi2Wi chip (based on
Marvell 88W8686) for wireless connectivity.
I have tested 2.6.34, 2.6.35, 2.6.36, 2.6.39 and 3.0 kernel versions.
On 2.6.34 and 2.6.35 WEP encryption in ad-hoc mode worked just fine.
Starting 2.6.36 kernel WEP is no more working. The latest tested
kernel version was 3.0 with no success. From what I understand there
was huge *libertas* driver rewrite (wext removed, cfg80211/nl80211 (?)
support). I assume that the following commit was included into 2.6.36
after checking ChangeLog-2.6.36-wireless and ChangeLog-2.6.36.

iwconfig successfully creates ad-hoc network and it's working with
other machines, but WEP encryption is missing. iwconfig continues to
show that encryption is enabled, but from other machines I can confirm
that it is fully publicly open. Could it be that this cfg80211 support
broke WEP encryption? It looks like it was the only commit that
modified required functions for brining WEP up.
