Features not implemented in your modem. Does it help to know that the driver is for a class of products, of which some cable modems just happen to fit? Dec 29 16:32:15 anderson kernel: CDCEther.c: Ethernet information found at device configuration. Trying to use it anyway. This is a design fault in your modem. The device descriptors are incorrect, but the CDCEther driver works around this. Dec 29 16:32:15 anderson kernel: CDCEther.c: Found Header descriptor, CDC version 110. Dec 29 16:32:15 anderson kernel: CDCEther.c: Imperfect filtering support - need sw hashing This means that the multicast filter cannot perrform "perfect filtering", which means that some multicast packets will be sent through to the device that do not match the multicast groups that your machine is a member of. Note that a cable modem doesn't need multicast - it is running point-to-point. Dec 29 16:32:15 anderson kernel: CDCEther.c: Can't use SetEthernetMulticastFilters request Your modem says that it doesn't support a particular command, which is optional according to the specification. Dec 29 16:32:15 anderson kernel: CDCEther.c: detected BULK OUT packets of size 64 This is how big the data packets from host to modem can be. Dec 29 16:32:15 anderson kernel: CDCEther.c: interrupt address: 5 This is actually bogus on your device. No interrupts get delivered. Dec 29 16:32:15 anderson kernel: CDCEther.c: interrupt interval: 64 So is this. Dec 29 16:32:15 anderson kernel: CDCEther.c: eth1: Thomson Consumer Electronics Thomson DCM245 Cable Modem 001095A4A496 This is who claims to make your modem, and its serial number. Dec 29 16:32:15 anderson kernel: CDCEther.c: eth1: 00:10:95:A4:A4:96 This is the MAC address. Usually the same as the serial number. Dec 29 16:33:07 anderson kernel: CDCEther.c: eth1: set multicast filters This means that the networking stack has called a particular member function... Dec 29 16:33:07 anderson kernel: CDCEther.c: eth1: too many MC filters for hardware, using allmulti But we can't implement multicast because of device limits. > I'm not finding much information about CDCEther module (like in Kernel > documentation). I think that's because of this that I have so many > questions... Most modules don't have much documentation. I guess I should write up a brief explaination though, since these questions keep coming up. Generally you are expected to read the source code if you want to know how it works.
