ath9k/ath5k + 80211s crash

[austinxxh-ath9k at yahoo.com]

ath9k + 80211s has no crash anymore. however after assigned IP to the mesh node, I could not ping at all, it's not working.

ath5k crashes on ar71xx boards, just learned it might have something to do with silicon bug from atheros instead of ath5k driver bug.
