Subject: Re: NAPI of many interfaces with just an interruption source

Thanks for your answers...

I understand that yes... if there is just an irq, the NAPI structure
should be one also...

The question is... I have one napi (inserted in an struct hss_t). This
hss structure has pointers to four struct port (each one is a network
device). So... When I detect the first IRQ, I can detect the dev
origin of the irq, and call netif_rx_schedule for it
(netif_rx_schedule(dev, &port->hss->napi).

In the poll function, I can obtain hss from napi, but not the dev
(unless I store the value of the last calling dev in hss_t). Is this
the way?

Thanks
