But if so, making a stronger layer 4 checksum can also solve this problem.
i.e. TCP with CRC32 or CRC64, instead of loosy 16-bit checksum.
It will solve the "core router" and the "important Ethernet switch"
mangling problem.
How? Core router wouldn't verify L4. Or is the proposal it should? So when
we introduce new L4, we need to update all L3 devices? Sounds like an
expensive layer violation.
It should not.
I say, that if TCP had a powerful checksum (like CRC32 or above),
Mangling problem would not occur at the Core Router level.
