Hello ppl ;-) I have some code for you to test with some initial ANI support, i 'm sure i miss something because it doesn't work after this (no rx) http://www.kernel.org/pub/linux/kernel/people/mickflemm/ath5k-ani.tar.bz2 Known bugs: a) On non-5212 hw it'll result a segfault because i don't check for chip version durring ani_reset but i do check durring attach (well most of you have 5212 chips so you won't hit this i guess). b) During attach i do a bad memory allocation ani_stats = kzalloc(sizeof(struct ath5k_ani_state), GFP_KERNEL); just change it to ani_stats = kzalloc(sizeof(struct ath5k_ani_stats), GFP_KERNEL); problem seems to be in the initial settings used, i'm working on it but the more people they check it out the faster we can make it work ;-) algo is the one described in the patent doc, not the one used on ath9k -- GPG ID: 0xD21DB2DB As you read this post global entropy rises. Have Fun ;-) Nick _______________________________________________ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel
