A quick look at the rt2x00pci.c file doesn't suggest that there's anything variable about the RX header though so I guess that indeed this may be a problem. > Anyway, I have worked on a fix for the padding and I'll commit it to > rt2x00.git first to see if anybody reports any problems with it before > sending it to wireless-dev. Great. I just posted a similar fix in the other thread for zd1211, does that look similar to yours as well? Should we have a static inline with this code "ieee80211_needs_padding()" or something? johannes
