Subject: [PATCH] public/io/netif.h: add a new extra type for XDP
Date: Mon, 18 May 2020 11:24:45 +0300	[thread overview]
Message-ID: <1589790285-1250-1-git-send-email-kda@linux-powerpc.org> (raw)

The patch adds a new extra type to be able to diffirentiate
between RX responses on xen-netfront side with the adjusted offset
required for XDP processing.

For Linux the offset value is going to be passed via xenstore.
