Date: Mon, 16 Jun 2014 10:00:14 +0200 From: Albert Krenz <albert.krenz87@...glemail.com> To: netdev@...r.kernel.org Subject: How does the linux kernel select the MAC address for TAP devices? As stated in the email subject: Where does the kernel get the used MAC-Adress for a newly create TAP device? Are they randomly generated or does it select one from a fixed pool of reserved MAC-Adresses? I have not found any official documentation about the selection of MAC-addresses for TAP-devices. Most sites like http://backreference.org/2010/03/26/tuntap-interface-tutorial/ state that the MAC addresses are auto-generated and can be changed. But they do not explain the generation rules. Does anyone know an official document (preferably from kernel.org) explaining the MAC selection process? Or is it only explained in the Source? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
