Subject: pull request: wireless-2.6 2008-04-01
Dave,
A few more for 2.6.25...one of them isn't really a bug fix, but
it includes messages which might be useful for future debugging.
All of them are relatively minor, but I think it would be good to
have them now rather than later.
Please let me know if there are problems!
Thanks,
John
