AFAIK, no driver does that today (although i really liked > that scheme, there is a lot of fscked hardware out there that wont work > well with that scheme). Where are the firemen when you need them? I am tempted to suggest we toss the document completely, for two reasons: 1) It's geared towards conversions, whereas %99.9999 of the conversions that will ever happen, have happened. Every single potential reader of this document is therefore writing new drivers with NAPI from the beginning. 2) Inaccurate documentation is often worse than no documentation. It's not a bad thing to delete the document, and also we have a lot of time until 2.6.24 finalizes with these changes and in that time someone with the right incentive could write a fresh new NAPI manual that represents reality. Such a document could be added after the merge window closes. This also reminds me that we confuse people by having two driver models for interrupt handling. I've been reluctant to remove the "optional" component of NAPI especially when it didn't handle multi-queue properly (which basically made drivers for virtualized devices impossible without using dummy devices for each queue). But that is no longer true and there isn't any reason for a new driver not to be NAPI from the beginning. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
