you'd think standard testing of traffic through the asic path somewhere between 'let's design an asic!' and 'here's your board ms customer!' would have found this sort of thing, no? or does testing only use 1 mac address ever?
Well, it's actually payload, rather than src/dst MAC used for forwarding, so there's quite a few more combinations to look for... 2^(8*9216) is quite a lot of different packets to test through the forwarding path... But, wait, that assumes every bit combination for 9216 byte packets, but the packet might be shorter than that... So multiply that by (9216-64). Anyone want to work out how many years that'd take to test, even at 100G? Simon
