OK I guess I can understand removing 10 (I personally haven't > seen one in a very long time) but 100 are omnipresent and most of my NICs > are in fact 100. Don't panic - they're talking about removing the 100 MBps NICS, not the 100 GBps NICs. Jokes aside - obviously there are very different populations of NICS. Here, the only 100MBps interface is in the IP phone, and I would guess that even most consumer hardware comes with a GBps interface on board (heck, even RPis have a GBit interface, even if can't use more than 30% of it's bandwith). Checking with a hardware-dealer: very few NICs in their catalog are 100MBps, most are gigabit-grade. I would have expected that things look different in the embedded world... On the other hand, some data centers I know routinely use 10GBps, and 1 GBps is considered "legacy" there. So, perceptions are very different... let's keep this rational and make a list of cards still in use. Regards, Christoph -- Spare Space
