Did I understand:
> 1) Chip has a "flow cache", LRU based, managed like routing caches You need the chip to support your technique.
No shit Sherlock.
But it should be noted that the idea can be fully verified in software by adding the scheme into the RX processing of some existing ethernet driver.
Are the vendors picking up on this?
If they're going to ignore my ideas, that's not my problem.
I still don't see how this gets rid of the copy_to_user space once you've gathered the buffers. How do you feed the user buffer addresses to the card?
You flip the pages into userspace, ie. you replace the page the user currently has with the one the networking buffer is using.
What technique are you using? Is it proprietary?
