Re: Request_irq fails for IRQ2

and no virtual irq will be allocated. As per your return value it seems the device node is not getting registered, perhaps the entry is missing in DTS file. Try with just ioremap and see if virtual irq is returned properly. Kind Regards, Vijay Nikam On Mon, Oct 3, 2011 at 7:57 PM, smitha.va

[gianfar]bandwidth management problem on mpc8313 based board

of the 4 ports should support 100Mbps bandwidth simultaneously (as base port is 1Gbps). Then why bandwidth gets reduced when more than one port are communicating simultaneously? Any reason or suggestion I should check for this problem? Kindly Please acknowledge, thanks Kind Regards, Vijay Nikam
