Subject: Question on documentation / Mellanox ConnectX-3
Date: Tue, 3 Apr 2018 14:59:38 -0300	[thread overview]
Message-ID: <20180403175938.GA23889@localhost.localdomain> (raw)

Hi,

http://docs.openvswitch.org/en/latest/howto/dpdk/ says:

Some NICs (i.e. Mellanox ConnectX-3) have only one PCI address
associated with multiple ports. Using a PCI device like above won’t
work. Instead, below usage is suggested:

$ ovs-vsctl add-port br0 dpdk-p0 -- set Interface dpdk-p0 type=dpdk \
    options:dpdk-devargs="class=eth,mac=00:11:22:33:44:55:01"
$ ovs-vsctl add-port br0 dpdk-p1 -- set Interface dpdk-p1 type=dpdk \
    options:dpdk-devargs="class=eth,mac=00:11:22:33:44:55:02"

But these MACs are 7 bytes long. Seems the idea was to mention the two
incremental MAC addresses that the ports have, and thus the ':55'
should have been removed from there, right?

Reading the code, it doesn't seem prepared to handle the extra byte in
any (special) way.
