So far, we retrieve both the used ring and avail ring idx by the var last_used_idx; it won't be a problem because the used ring is updated immediately after those avail entries are consumed. But that's not true when dequeue zero copy is enabled, that used ring is updated only when the mbuf is consumed. Thus, we need use another var to note the last avail ring idx we have consumed. Therefore, last_avail_idx is introduced. Signed-off-by: Yuanhan Liu <yuanhan.liu@linux.intel.com> Reviewed-by: Maxime Coquelin <maxime.coquelin@redhat.com> Tested-by: Qian Xu <qian.q.xu@intel.com> |
