Pro: Simple, faster than programmed I/O, and allows random access to packets. Where possible, the linux drivers compute the checksum of incoming IP packets as they are copied off the card, resulting in a further reduction of CPU usage vs. an equivalent PIO card.
Con: Uses up memory space (a big one for DOS users, essentially a non-issue under Linux), and it still ties up the CPU. |
