From: Chengchang Tang Date: Fri, 10 Apr 2020 11:09:24 +0000 (+0800) Subject: net/hns3: fix adding multicast MAC address X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fb94f359481ff6d53f6b7850d3ad393addfb6afb;p=dpdk.git net/hns3: fix adding multicast MAC address Currently, when upper application calls the rte_eth_dev_mac_addr_add API function to add a MC mac address based on hns3 PF/VF device, it will fail. In hns3 network engine adding UC and MC mac address with different commands with firmware. We need to determine whether the input address is a UC or a MC address to call different commands in the '.mac_addr_add' and '.mac_addr_remove' ops implementation functions in hns3 PF and VF driver as below: hns3_add_mac_addr hns3vf_add_uc_mac_addr hns3_remove_mac_addr hns3vf_remove_mac_addr By the way, it is recommended calling the rte_eth_dev_set_mc_addr_list API function to set the MC mac address, because using the rte_eth_dev_mac_addr_add API function to set MC mac address may affect the specifications of UC mac addresses.
