+Patch name: patch.tun-tap
+Author: renzo davoli <renzo@cs.unibo.it>
+Date: Mon, 1 Apr 2002 19:13:53 -0500 (EST)
+
+Detailed description (from Renzo's message):
+
+I have ported the ne2k emulation from ethertap to tun-tap
+interface.  ethertap in fact will not be supported in kernel 2.5
+and tuntap allows the dynamic creation of interfaces at user
+level.
+
+I have patched the file iodev/eth_tap.cc
+
+Patch was created with:
+  cvs diff -u
+Apply patch to what version:
+  cvs checked out on DATE, release version VER
+Instructions:
+  To patch, go to main bochs directory.
+  Type "patch -p0 < THIS_PATCH_FILE".
