VIRTIO-134: Spell out details of indirect elements in chains
1) It's implied that a chain terminates with an indirect descriptor (since VIRTIO-15) but we didn't spell out that a device MUST NOT continue it. 2) We allow [direct]->[direct]->[indirect], and qemu and bhyve both accept it. Make it clear that this is valid, thus devices MUST handle it. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Michael S.
