Added default MAC replay as well. Fixes: 4bdefaade6d1 ("ethdev: VMDQ enhancements") --- v2: Added default MAC replay & Code optimization v3: Covered a case (ex, SR-IOV) where multiple pools exist in the mac_pool_sel array. v4: removed a coding style warning Signed-off-by: Steve Shin --- lib/librte_ether/rte_ethdev.c | 43 ++++++++++++++++++++++++------------------- 1 file changed, 24 insertions(+), 19 deletions(-) diff --git a/lib/librte_ether/rte_ethdev.c b/lib/librte_ether/rte_ethdev.c index 4790faf..166ffa6 100644 --- a/lib/librte_ether/rte_ethdev.c +++ b/lib/librte_ether/rte_ethdev.c @@ -931,34 +931,39 @@ rte_eth_dev_config_restore(uint8_t port_id) { struct rte_eth_dev *dev; struct rte_eth_dev_info dev_info; - struct ether_addr addr; + struct ether_addr *addr; uint16_t i; - uint32_t pool = 0; + uint32_t pool; + uint64_t pool_mask; dev = &rte_eth_devices[port_id]; rte_eth_dev_info_get(port_id, &dev_info); - if (RTE_ETH_DEV_SRIOV(dev).active) - pool = RTE_ETH_DEV_SRIOV(dev).def_vmdq_idx; + /* replay MAC address configuration including default MAC */ + if (*dev->dev_ops->mac_addr_set != NULL) { + addr = &dev->data->mac_addrs[0]; + (*dev->dev_ops->mac_addr_set)(dev, addr); + } - /* replay MAC address configuration */ - for (i = 0; i < dev_info.max_mac_addrs; i++) { - addr = dev->data->mac_addrs[i]; + if (*dev->dev_ops->mac_addr_add != NULL) { + for (i = 1; i < dev_info.max_mac_addrs; i++) { + addr = &dev->data->mac_addrs[i]; - /* skip zero address */ - if (is_zero_ether_addr(&addr)) - continue; + /* skip zero address */ + if (is_zero_ether_addr(addr)) + continue; - /* add address to the hardware */ - if (*dev->dev_ops->mac_addr_add && - (dev->data->mac_pool_sel[i] & (1ULL << pool))) - (*dev->dev_ops->mac_addr_add)(dev, &addr, i, pool); - else { - RTE_PMD_DEBUG_TRACE("port %d: MAC address array not supported\n", - port_id); - /* exit the loop but not return an error */ - break; + pool = 0; + pool_mask = dev->data->mac_pool_sel[i]; + + do { + if (pool_mask & 1ULL) + (*dev->dev_ops->mac_addr_add)(dev, + addr, i, pool); + pool_mask >>= 1; + pool++; + } while (pool_mask); } } -- 2.9.3
