Well I understand it's just a linked list with aprox 128 nodes. That should 
be OK on decent RAM and CPU.

They have nothing to do with NICs, they have to do with OS implementation.

NICs talk on ethernet level, and I don't know any NIC's designed with 
special hardware for handling IP aliases. Intel's FXPs rule, because they 
even do CRC and QoS with microchip:).

Probably his point was no-name hardware with small buffers may add to the 
latency.
