Subject: [dpdk-dev] [PATCH v3 3/3] mlx4,5: handle 32 bit PCI domain
Date: Wed, 5 Jul 2017 09:55:33 -0700 [thread overview]
Message-ID: <20170705165533.20581-4-stephen@networkplumber.org> (raw)
In-Reply-To: <20170705165533.20581-1-stephen@networkplumber.org>
The PCI domain in Azure maybe 32 bits. When device is passed through
the domain is synthesize from the internal GUID. The code that
parses for PCI address in Mellanox drivers needs to use wider
scanf format.
