| Called by the kernel interrupt handler when the card reports that there is data on the card. It pulls the data off the card, packages it into a sk_buff and lets the kernel know the data is there for it by doing a netif_rx(sk_buff). You need to know how to enable interrupt generation upon Rx of data, how to check any relevant Rx status bits, and how to get that data off the card (again sh mem, PIO, DMA, etc.) |
