I am currently investigating on how easy it is to transform a kernel network device driver into a dynamically loadable module. I found and loaded the if_disc.ko module into memory, it seems to work fine because I have a new entry with ifconfig -a. I have no idea what this pseudo network interface is for, and I could not find any man on it. Any idea, pointers ? Where could I find the source ? I wrote a network device driver for a very specialized satellite reception card. This driver is compiled, as most of the network drivers, in the kernel. I am just wondering if it is possible to make this driver a loadable module. Assuming that the board is in on PCI bus, supports DMA bus mastering, may transfer data up to 40Mbps. Any idea, pointers ? What should I pay attention to, what are the limits... ?
