I suppose I can post it as a patch on savannah. I forgot, I also
developed a driver for the on-chip FEC+PHY of FreeScale's MCF5223x. It
does zero-copy receive. I'll post it as well,
No, I didn't do any filtering in the driver. But filtering IP
addresses and ports in the driver would be straightforward, wouldn't
it? Just match the appropriate fields from IP header against the
whitelist.
