After reading the ip_dummynet.c, I found that dummynet
uses link list to store packets as the following code:
if (q->head == NULL)
q->head = pkt;
else
DN_NEXT(q->tail) = pkt;
q->tail = pkt;
q->len++;
q->len_bytes += len ;
However, when I tried to use the following function to
get the length of the queue, I get the different value
to the q->len and the return is always 1.
static int getQueueLen(struct dn_flow_queue *q){
struct dn_pkt * pFirst;
int i;
pFirst = q->head;
for(i = 1 ; (pFirst != NULL); i ++){
pFirst = DN_NEXT(pFirst);
}
return i;
}
I donot know why this happens. Please help me slove
this problem. Million thanks.
