If the current system time exceeds the device’s trans_start time by at least the timeout period, the networking layer will eventually call the driver’s tx_timeout method. This is the one which differentiates a Linux device driver from a Windows device driver from a MAC device driver. However, the OS-specific portion is the one that is tightly coupled with the OS mechanisms of user interfaces, and thus differentiates a Linux device driver from a Windows device driver and from a MacOS device driver. The device driver is a kernel component (usually a module) that interacts with a hardware device.
