Adjustable Packet Length

[k-cross]

The packet diagram is great for highly specific packet widths for networking protocols, but it would be more useful to be able to adjust the width of bit representations as right now they are all static 32 bit widths.

Operating system memory layouts; cpu registers; other network protocols like IPv6 (128 bit width) would all benefit from adjustable widths.

Collapsing multi-height rows into a single field would make it easier to read unique fields too. Wikipedia's TCP packet representation for context.
