97f24a0496be9e0a7216fea1fa0d54c1db9066e2 vhost-user.rst: clarify when FDs can be sent
Previously the spec did not say where in a message the FDs should be
sent. As I understand it, FDs transferred in ancillary data will
always be received along with the first byte of the data they were
sent with, so we should define which byte that is. Going by both
libvhost-user in QEMU and the rust-vmm crate, that byte is the first
byte of the message header. This is important to specify because it
would make back-end implementation significantly more complicated if
receiving file descriptors in the middle of a message had to be
handled.
