From e5dc0b402e64d245956c47cf22776e5206f322dc Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Wed, 30 Jan 2013 19:12:33 +0800 Subject: tap: introduce a helper to get the name of an interface This patch introduces a helper tap_get_ifname() to get the device name of tap device. This is needed when ifname is unspecified in the command line and qemu were asked to create tap device by itself. In this situation, the name were allocated by kernel, so if multiqueue is asked, we need to fetch its name after creating the first queue. Only linux has this support since it's the only platform that supports multiqueue tap.
