devices: vhost handling VHOST_USER_SET_FEATURES
Some combinations of new qemu (2.11) and old dpdk (16.10) may send VHOST_USER_SET_FEATURES at the end of the protocol exchange which the vhost interface is already declared up and ready. Unfortunately, the process of VHOST_USER_SET_FEATURES will cause the interface to go down. Not sure if it is correct or needed. Because there is no additional messages thereafter, the hardware interface stays down. The fix is to check the interface again at the end of processing VHOST_USER_SET_FEATURES. If it is up and ready, we bring back the hardware interface. Type: fix Change-Id: I490cd03820deacbd8b44d8f2cb38c26349dbe3b2 Signed-off-by: Steven Luong <sluong@cisco.com>
