Hi Marcelo, I haven't used the specific cards referred to in the surrounding documentation but I don't think the 'mac' address format is a typo.
The notation is specific to some vendor NICs that have several Ethernet devices sharing a single PCI bus:device.function address. In that case the PCI address alone cannot distinguish the Ethernet device to be uses ofr the dpdk port. "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::" Regards, Billy. > -----Original Message----- > From: [email protected] [mailto:ovs-dev- > [email protected]] On Behalf Of Marcelo Ricardo Leitner > Sent: Monday, April 9, 2018 6:21 PM > To: [email protected] > Cc: [email protected]; [email protected] > Subject: [ovs-dev] [PATCH] netdev-dpdk: fix MAC address in port addr example > > The MAC address is always 6-bytes long, never 7.
