Hi, am I understand it right that I can not use NAPI-powered design in case when there is only one rx queue and one tx queue (only two dma channels) usable for data transfer with the ethernet controller for all interfaces (2 ports or more)?
I could imagine there would be possibility to declare for example rx queue sharable between napi interfaces, but I was not able to find anything like that. I agree that it is a bit strange configuration but we have to support such corner case (when other dma channels are used by independent systems). I seems like I have to create two drivers - one with napi, when at least the same number of dma channels are free for use and second one without napi (because of not enough dma channels). Thanks. /Jan
