[dpdk-dev] [PATCH 4/4] vhost: enable log_shmfd protocol feature

[Yuanhan Liu <yuanhan.liu@linux.intel.com>]

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.
