[Tfug] Ethernet frame "immutables" wrt switch silicon

Hi,

[Probably too technical, here, but worth a shot...]

What's the smallest portion (i.e., individual fields) of the ethernet
frame that switch silicon must recognize?

Then, the more important question, what is the *most* that it can
("safely") recognize/act on?

I've started digging through datasheets but this seems to be one of
those issues where there is a lot "unsaid"/assumed by manufacturers.

Thx,
