Andrey V. Elsukov 978f2d1728 Add "tcpmss" opcode to match the TCP MSS value.
With this opcode it is possible to match TCP packets with specified
MSS option, whose value corresponds to configured in opcode value.
It is allowed to specify single value, range of values, or array of
specific values or ranges. E.g.

 # ipfw add deny log tcp from any to any tcpmss 0-500
