Also it correctly updates the amount of > available skb. I'm seeing issues on a number of machines with the ehea device. Sometime after boot I see a bunch of: ehea: Error in ehea_proc_rwqes: LL rq1: skb=NULL ehea: Error in ehea_proc_rwqes: LL rq1: skb=NULL ehea: Error in ehea_proc_rwqes: LL rq1: skb=NULL ehea: Error in ehea_proc_rwqes: LL rq1: skb=NULL which eventually stop. - for (i = 0; i < pr->rq1_skba.len; i++) { + for (i = 0; i < nr_rq1a; i++) { It looks like you are now only initialising half the ring, but still telling the hardware to use the whole ring. Once you get through the entire ring once the errors go away.
