Subject: [PATCH net-next 03/13] nfp: parse the mailbox cmsg TLV
Date: Wed, 5 Jun 2019 14:11:33 -0700 [thread overview]
Message-ID: <20190605211143.29689-4-jakub.kicinski@netronome.com> (raw)
In-Reply-To: <20190605211143.29689-1-jakub.kicinski@netronome.com>
Parse the mailbox TLV. When control message queue is not available
we can fall back to passing the control messages via the vNIC
mailbox.
