commit 54f9e32305d4a8d30c2a4ae059d310189b312498
Author: Yuanhan Liu <yuanhan.liu@linux.intel.com>
Date: Fri Jan 29 12:57:56 2016 +0800
vhost: handle dirty pages logging request
VHOST_USER_SET_LOG_BASE request is used to tell the backend (dpdk
vhost-user) where we should log dirty pages, and how big the log
buffer is.
This request introduces a new payload:
typedef struct VhostUserLog {
uint64_t mmap_size;
uint64_t mmap_offset;
} VhostUserLog;
Also, a fd is delivered from QEMU by ancillary data.
With those info given, an area of memory is mmaped, assigned
to dev->log_base, for logging dirty pages.

vhost: claim support of guest announce
It's actually a feature already enabled in Linux kernel (since v3.5).
What we need to do is simply to claim that we support such feature,
and nothing else.
With that, the guest will send an ARP message after live migration
to notify the switches about the new location of migrated VM.

vhost: enable log_shmfd protocol feature
To claim that we support vhost-user live migration support:
SET_LOG_BASE request will be send only when this feature flag
is set.
Besides this flag, we actually need another feature flag set
to make vhost-user live migration work: VHOST_F_LOG_ALL.
Which, however, has been enabled long time ago.
