Amazing, I have been struggling with the fact that my ricochet wireless modem wouldn't work with the 2.1 kernels for months. I never could figure out why I could get UDP through but not TCP.
Can anyone explain why van jacombson compression doesn't work? Is it a problem with pppd, the 2.2 kernel or the the other side? (the ricochet and I guess the van jacobson compression by extension work with 2.0.36)
