The source IP, in IPv4 or IPv6 format, and the source port: + + src 192.168.0.1 1024 + + src 2001:DB8:85A3:0:0:8A2E:370:7000 1024 + +* dst: A pair of destination address values. The destination IP, in IPv4 or IPv6 format, and the destination port. + +* flexbytes: A 2-byte tuple to be matched within the first 64 bytes of a packet. + +The offset where the match occurs is set by the --pkt-filter-flexbytes-offset command-line parameter +and is counted from the first byte of the destination Ethernet MAC address. +The default offset is 0xC bytes, which is the "Type" word in the MAC header. +Typically, the flexbyte value is set to 0x0800 to match the IPv4 MAC type or 0x86DD to match IPv6. +These values change when a VLAN tag is added. + +* vlan: The VLAN header to match in the packet. + +* queue: The index of the RX queue to route matched packets to. + +* soft: The 16-bit value in the MBUF flow director ID field for RX packets matching the filter. +
