virtio-net : 5.1.6.2 descriptor-chains on transmitq

[Awais Masood <awais@bedrocksystems.com>]

Hi,

Seeking some clarity on:

 5.1.6.2
 Packet Transmission

 5. The header and packet are added as one output descriptor to the
transmitq, and the device is notified of the new entry

Does it imply no descriptor-chains for packets in transmitq? If
descriptor-chains are allowed on transmitq then why does it not state
'output buffer' instead of 'output descriptor'?

Regards,
Awais
