The supplicant logs below seem to indicate that you may not have the
changes required to do mesh node authentication.  Try to find out if
that compat-wireless has, for instance, this patch:
http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commit;h=71839121a0f35f9968d2e204a76eb22683156fd8

Cheers,
