+Regression - bridged networking broken for Mac OS X guest
+
+Using the instructions at http://www.contrib.andrew.cmu.edu/~somlo/OSXKVM/ for running Mac OS X Snow Leopard under QEMU, bridged networking is broken when using QEMU git. The result is that Mac OS X is unable to obtain an IP address using DHCP. It works in the latest stable release - QEMU 2.3.0.
+
+Replace "-netdev user,id=hub0port0" with "-netdev bridge,br=br0,id=hub0port0" when testing bridged networking.
+
+Bisecting the git repository shows the following bad commit:

+    tap: Drop tap_can_send
+
+    This callback is called by main loop before polling s->fd, if it returns
+    false, the fd will not be polled in this iteration.
+
+    This is redundant with checks inside read callback. After this patch,
+    the data will be sent to peer when it arrives. If the device can't
+    receive, it will be queued to incoming_queue, and when the device status
+    changes, this queue will be flushed.
