Re: Still [OT] Do Realtek NICs drop packets? Was: [OT] DEC Tulip NICs

I havnt noticed any get dropped, although of course the tcp stack might
just be recovering from it. I belive the problem with 8139s is bad
design where the packet has to be paragraph aligned to send it to the
card or something like that, so there is an aditional memcopy that
increases load and overhead. This makes them unsuitable for big servers,
but for home networks they are fine.
