I don't know how to relate > the port instance (NPE A,B,C) to the two time stamping channels. I assume you mean this: + * PHYSICAL_ID(p->id) ? + * TODO - Figure out correct mapping. Unfortunately I can's find this information in the devel manual. I think there are 3 channels (not two), each for one Ethernet port. IXP465 can have a port on each NPE. PHYSICAL_ID etc. are described at the start of the file: * logical port 0x00 0x10 0x20 * NPE 0 (NPE-A) 1 (NPE-B) 2 (NPE-C) * physical PortId 2 0 1 This means the first port (usually "eth0") is connected to NPE-B, the second port to NPE-C, and the third port to NPE-A (not available on IXP42x). Also, the manual says NPE-B can serve 3 additional Ethernet ports (6 total). I only have access to IXP425 (and 421) hardware. I think someone with the actual IXP465 has to check the details. -- Krzysztof Halasa -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
