Unlike for block and character drivers, you do not specify network driver entry points in the dsent data structure. This means that a network driver has no exposure into the file system and, therefore, has no entry in the /dev directory. Thus, network drivers do not have block and character driver-specific interfaces such as open, close, read, write, and strategy.
