[PATCH v4 07/23] net/ice: support dcf MAC configuration

[Kevin Liu <kevinx.liu@intel.com>]

Below PMD ops are supported in this patch:
    .mac_addr_add      = dcf_dev_add_mac_addr
    .mac_addr_remove   = dcf_dev_del_mac_addr
    .set_mc_addr_list  = dcf_set_mc_addr_list
    .mac_addr_set      = dcf_dev_set_default_mac_addr
