i'm not sure if i understand you right... but you don't need to call rxbuf_setup() for the hardware to be able to move on. the hardware reads the ds_link pointer and moves to the next descriptor when it has finished receiving one descriptor. but of course if your jobQueue is too late receiving pakckets, there might not be a next descriptor to move to. so maybe it could help to increase the number of ATH_RXBUF? bruno _______________________________________________ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel
