the first bad commit is commit a90a7425cf592a3afeff3eaf32f543b83050ee5c Author: Fam Zheng <f...@redhat.com> Date: Thu Jun 4 14:45:17 2015 +0800
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.
