Thus, replaces memcpy by only updating the required fields at the driver layer. error log: testpmd> show port info 1 **** Infos for port 1 **** MAC address: 00:00:00:00:00:00 Device name: net_softnic0 Segmentation fault. port_infos_display (port_id=1) at /dpdk/app/test-pmd/config.c:418 if (dev_info.device->devargs && dev_info.device->devargs->args) Fixes: cc6d421574fe ("net/softnic: add softnic PMD") Cc: stable@dpdk.org Signed-off-by: Jasvinder Singh Reviewed-by: Ferruh Yigit --- diff --git a/drivers/net/softnic/rte_eth_softnic.c b/drivers/net/softnic/rte_eth_softnic.c index 743a7c5854..14d4a10308 100644 --- a/drivers/net/softnic/rte_eth_softnic.c +++ b/drivers/net/softnic/rte_eth_softnic.c @@ -59,23 +59,6 @@ static const struct softnic_conn_params conn_params_default = { .msg_handle_arg = NULL, }; -static const struct rte_eth_dev_info pmd_dev_info = { - .min_rx_bufsize = 0, - .max_rx_pktlen = UINT32_MAX, - .max_rx_queues = UINT16_MAX, - .max_tx_queues = UINT16_MAX, - .rx_desc_lim = { - .nb_max = UINT16_MAX, - .nb_min = 0, - .nb_align = 1, - }, - .tx_desc_lim = { - .nb_max = UINT16_MAX, - .nb_min = 0, - .nb_align = 1, - }, -}; - static int pmd_softnic_logtype; #define PMD_LOG(level, fmt, args...) \ @@ -86,7 +69,9 @@ static void pmd_dev_infos_get(struct rte_eth_dev *dev __rte_unused, struct rte_eth_dev_info *dev_info) { - memcpy(dev_info, &pmd_dev_info, sizeof(*dev_info)); + dev_info->max_rx_pktlen = UINT32_MAX; + dev_info->max_rx_queues = UINT16_MAX; + dev_info->max_tx_queues = UINT16_MAX; } static int
