It was introduced a while after the original GET/SET_CONFIG
implementation in QEMU, but within the same QEMU release (2.12?).
It is required by the vhost-user spec. Rte_vhost doesn't check
it, so everything worked so far, but other implementations
might (and should) reject our GET_CONFIG requests right now.
As a part of this feature, we should also check the same
flag before sending GET/SET_CONFIG messages to respect those
devices that really don't implement F_CONFIG. This is done
in a separate patch.
