And it is enabled by default. For the following two rules: rule0: pattern: eth type is 0x0806 actions: queue index 3 rule1: pattern: eth type is 0x0806 / vlan vid is 20 actions: queue index 4 If enable VLAN number, only the ARP packets with VLAN 20 are directed to queue 4, and the ARP packets with other VLAN ID cannot be directed to the specified queue. If app want to all ARP (VLAN or no VLAN) packets to be directed to the specified queue, app has to set many rules for VLAN packet. In this case, if driver doesn't enable VLAN number, app just need to set one rule (rule0). So this patch adds a "fdir_vlan_match_mode" runtime config which only can be 'strict' or 'nostrict'. And driver still uses 'strict' mode as the default mode. Please select 'nostrict' mode if you request all same ethertype packets with and without VLAN to a specified queue.
