[Intel-wired-lan] fm10k driver questions

I have a few Intel FM10420 based devices (Supermicro AOC-S100G-i2C) that I
am trying to get working in our lab using dpdk and some of the network
virtualization functions of the card. However, I am a bit confused on the
two different sources of kernel drivers. In the documentation here
instructions include passing parameters to the fm10k kernel module. In
looking at source
fm10k I see no such parameters and modinfo supports that. Then I found a
set of Intel drivers that do seem to support these options. Could someone
please tell me the relationship between these two source trees?
As I understand it this is the mailing list for the source tree within the
kernel, and I would prefer to work with these sources. However when I load
the kernel module I am having issues using the card, both as a kernel
controlled Ethernet card and as a dpdk device. On the dpdk side of things I
get an error saying the switch is not ready (PMD: eth_fm10k_dev_init():
switch is not ready), I have been looking for a way to make the switch
ready through the kernel driver but have not found anything, any thoughts?
In using the card as a kernel controlled Ethernet card, I have simply
loaded the kernel module, it gets assigned to 'ens1' I bring the link up
and assign and assign an IP address and try to ping another machine on the
same subnet to no avail. I have also noticed that ethtool does not really
seem to understand this card.
Below is some relevant information from my system. Thank you for your time!
