Master network devices are regular, unmodified Linux network device drivers for the CPU/management Ethernet interface. Such a driver might occasionally need to know whether DSA is enabled (e.g.: to enable/disable specific offload features), but the DSA subsystem has been proven to work with industry standard drivers: e1000e, mv643xx_eth etc. without having to Feb 26, 2018 · David Davis, author of "The Gorilla Guide to Linux Networking 101", as he reviews Linux network interfaces and demos working in a debian linux system.
