From 1422e32db51ff2b1194fb24a6201c4310be5667d Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 24 Oct 2012 08:43:34 +0200 Subject: net: reorganize headers Move public headers to include/net, and leave private headers in net/. Put the virtio headers in include/net/tap.h, removing the multiple copies that existed. Leave include/net/tap.h as the interface for NICs, and net/tap_int.h as the interface for OS-specific parts of the tap backend.
