The base relative to which 'offset' is measured. Possible values are:
- IPV4: Points to the beginning of the IPv4 header.
- IPV6: Points to the beginning of the IPv6 header.
- TCP: Points to the beginning of the TCP header, skipping
over any IPv4 options or IPv6 extension headers. Not present for
non-first fragments.
- UDP: Points to the beginning of the UDP header, skipping
over any IPv4 options or IPv6 extension headers. Not present for
non-first fragments.

Check the Base enum for the list of possible values.

If specified, apply this mask (bitwise AND) to the field to ignore bits
before matching. Encoded as a hexadecimal number (starting with "0x").
The last byte of the field (in network byte order) corresponds to the
least significant byte of the mask.
