On the DPDK page (https://files.ettus.com/manual/page_dpdk.html) the
following statement is made:
“Device discovery via DPDK is not currently implemented, so the device
args |mgmt_addr|, |addr|, and |second_addr| (if applicable) must all
be specified at runtime. There is no mechanism for MPM's TCP/IP
control traffic to flow over a link that is occupied by DPDK, so
mgmt_addr must point to a link that is not used for CHDR, such as
N310's RJ45 port.”
I’ve been using the X310 without DPDK with dual 10Gb SPI/SFP+
connections (192.168.30.2, 192.168.40.2). Once I start DPDK, ifconfig
no longer shows the NICs at all, which I assume is what it is supposed
to be doing. My question is, what is the ‘mgmt_addr’ ? I’ve never used
it before when using the X310. And how do I make sure the mgmt_addr
isn’t using a CHDR link? The X310 only has two RJ45s, right – and
they’re both being used by DPDK.
Thanks,

/Actualy the X310 has two *SFP+* connections, and an RJ-45 connection.
Now, on yours, you may have put SFP+ to RJ-45 adaptors on, but
natively they're SFP+. The single RJ-45 connector is the
"management port"--which can also support data transfer at lower speeds.
