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. _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
