This driver implements the "Communication Device Class" (CDC)
Ethernet Control Model. That protocol is often avoided with pure
Ethernet adapters, in favor of simpler vendor-specific hardware,
but is widely supported by firmware for smart network devices.
This driver implements Ethernet style communication, in either
of two ways:
- The "Communication Device Class" (CDC) Ethernet Control Model.
That protocol is often avoided with pure Ethernet adapters, in
favor of simpler vendor-specific hardware, but is widely
supported by firmware for smart network devices.
- On hardware can't implement that protocol, a simpler approach
is used, placing fewer demands on USB.
Within the USB device, this gadget driver exposes a network device
"usbX", where X depends on what other networking devices you have.
Treat it like a two-node Ethernet link: host, and gadget.
The Linux-USB host-side "usbnet" driver interoperates with this
driver, so that deep I/O queues can be supported. (On 2.4 kernels,
use "CDCEther" instead.) Deep queues are especially important with
high speed devices. It should also interoperate with standard CDC
Ethernet class drivers on other host operating systems.
driver, so that deep I/O queues can be supported. On 2.4 kernels,
use "CDCEther" instead, if you're using the CDC option. That CDC
mode should also interoperate with standard CDC Ethernet class
drivers on other host operating systems.
Say "y" to link the driver statically, or "m" to build a
dynamically linked module called "g_ether".
