Hello!
We have an X410 connected to a host computer through two QSFP28-to-QSFP28
connections with IPs 192.168.10.2 and 192.168.20.2 for interfaces 0 and 1
respectively. The X410 also has an ethernet connection to a router with an IP
192.168.1.19, which the host computer is also connected to.
When the X410 is loaded with the UC_200 image, everything seems to work as
desired and running "uhd_find_devices" on its own produces:
\[INFO\] \[UHD\] linux; GNU C++ version 9.4.0; Boost_107100; DPDK_19.11;

mgmt_addr: 192.168.20.2

When I try to change images with "uhd_image_loader --args
type=x4xx,mgmt_address=192.168.1.19,fpga=CG_400 ", it seems to work but then
errors out:

But if I run uhd_find_devices again I get what I expect :

Device Address:

mgmt_addr: 192.168.20.2
name: ni-x4xx-326E872
product: x410
type: x4xx
If I try and run any script though, even specifying the addresses, I get the
same errors as when changing the image. An example is with 'uhd_usrp_probe
--args "mgmt_addr=192.168.1.19,type=x4xx" ' even without any arguements:

The errors disappear when I use addr0 instead of mgmt_addr or addr. Since this
option is not listed in the wiki
(https://files.ettus.com/manual/page_usrp_x4xx.html#x4xx_usage_args) I am
curious if I am using it correctly. At the end of the day, I want to make sure
that when using the CG_400 image that both QSFP28 interfaces are operating, and
that I can switch between the two images without errors. Previously we used to
only have a single connection.
Thanks!
Zack
