Many Operating Systems will detect more than one valid interface, capable of reaching the internet, and setup each of them for carrying traffic to the internet Master network devices¶. 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. 3.2.
