From c2941df015f27490444428cd50964ea9f0bf49d4 Mon Sep 17 00:00:00 2001 From: Balazs Nemeth Date: Fri, 28 Nov 2014 09:21:45 +0000 Subject: [PATCH] ixgbe: fix mbuf failure statistics in vector Rx The statistics that is reported through the rx_nombuf fields in struct rte_eth_stats was not set when the vector PMD was used. The statistics should report the number of mbufs that could _not_ be allocated during rearm of the RX queue. The non-vector PMD reports it correctly. The use of either vector PMD or non-vector PMD depends on runtime configuration. Hence it is possible that a change in configuration would disable this statistics. To prevent this from happening, the statistics should be reported by both implementations.
