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.
