Subject: [RFC PATCH v8 10/19] virtio/vsock: defines and constants for SEQPACKET
Date: Tue, 13 Apr 2021 15:44:27 +0300	[thread overview]
Message-ID: <20210413124430.3403036-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210413123954.3396314-1-arseny.krasnov@kaspersky.com>

This adds set of defines and constants for SOCK_SEQPACKET
support in vsock.

Signed-off-by: Arseny Krasnov <arseny.krasnov@kaspersky.com>
---
v7 -> v8:
 - Things like SEQ_BEGIN, SEQ_END, 'msg_len' and 'msg_id' now removed.
   Now only last RW packet of each message marked by 'VIRTIO_VSOCK_SEQ_EOR'
   bit in 'flags' field of header.
