Since this is a new driver. added an AI review of documentation (features matrix) vs code Implemented (ops wired up): Feature Status Evidence Speed capabilities ✅ dev_infos_get reports speed_capa Link speed configuration ✅ dev_set_link_up / dev_set_link_down Link status ✅ link_update Link status event ✅ LSC interrupt handler + SXE_IRQ_LINK_UPDATE Rx interrupt ✅ rx_queue_intr_enable / rx_queue_intr_disable Queue start/stop ✅ rx_queue_start/stop, tx_queue_start/stop MTU update ✅ mtu_set Scattered Rx ✅ scattered_rx logic in queue configure LRO ✅ LRO Rx burst functions TSO ✅ TSO offload in tx_offload_capa Promiscuous mode ✅ promiscuous_enable / promiscuous_disable Allmulticast mode ✅ allmulticast_enable / allmulticast_disable Unicast MAC filter ✅ mac_addr_add / mac_addr_remove / mac_addr_set Multicast MAC filter ✅ set_mc_addr_list RSS hash ✅ rss_hash_update / rss_hash_conf_get RSS key update ✅ via rss_hash_update RSS reta update ✅ reta_update / reta_query VMDq ✅ VMDQ configure code present SR-IOV ✅ VF driver in patch 13, sxe_vt_configure DCB ✅ get_dcb_info, DCB configure functions VLAN filter ✅ vlan_filter_set Flow control ✅ flow_ctrl_get / flow_ctrl_set / priority_flow_ctrl_set CRC offload ✅ RTE_ETH_RX_OFFLOAD_KEEP_CRC handling VLAN offload ✅ vlan_offload_set / vlan_strip_queue_set / vlan_tpid_set L3/L4 checksum offload ✅ In offload capabilities Packet type parsing ✅ dev_supported_ptypes_get, ptype tables Timesync ✅ Full set of timesync ops Rx descriptor status ✅ Assigned to eth_dev->rx_descriptor_status Tx descriptor status ✅ Assigned to eth_dev->tx_descriptor_status Basic stats ✅ stats_get / stats_reset Extended stats ✅ xstats_get / xstats_reset / xstats_get_names Stats per queue ✅ queue_stats_mapping_set FW version ✅ fw_version_get Registers dump ✅ get_reg Module EEPROM dump ✅ get_module_info / get_module_eeprom Linux ✅ Platform code present x86-64 ✅ SIMD code in patch 12 Claimed but NOT implemented (no ops wired): Feature Status Notes EEPROM dump ❌ No get_eeprom_length or get_eeprom ops wired. sxe.ini claims EEPROM dump = Y but there's no get_eeprom callback in sxe_eth_dev_ops. Module EEPROM (get_module_eeprom) is present but that's a different feature. Power mgmt address monitor ❓ No get_monitor_addr op visible in the ops struct. This feature requires the PMD to implement get_monitor_addr to support rte_power_monitor(). QinQ offload ❓ Claimed as P (partial). vlan_tpid_set is present, but I didn't see explicit QinQ double-tag handling in the offload path. The overhead calculations reference 2 * SXE_VLAN_TAG_SIZE suggesting awareness, but the actual hardware offload for QinQ insertion/stripping needs verification. Inner L3/L4 checksum ❓ Claimed as P. The ptype tables cover NVGRE/VXLAN tunnel types, but whether inner checksum offload is actually wired in the Tx path needs verification against the offload capabilities returned. ARMv8 ❓ Claimed as Y but the SIMD code in patch 12 appears to be x86-specific (SSE/AVX). No NEON intrinsics visible.
