Hence it is statically linked code.
If I try

But I am not seeing any output

Indeed, DPDK provides a userspace driver for some NetXtreme nics
(which is net/bnxt).
This userspace driver does not rely on the bnxt Linux kernel driver.
IOW, this card being detecting and working with the Linux kernel does
not automatically mean that this nic can work with DPDK.

We need more info on your nic, first.

Can you share the pci id of this nic (like running lspci -n -s $pci_address= )?
It should be a 14e4:XXXX.

Then you can check this XXXX against what your dpdk application supports.
If it is a statically linked application, you can run:
$ dpdk-pmdinfo.py /path/to/your/application

Else, if your application is dynamically linked against DPDK driver,
you can run this command against the net/bnxt driver .so.22 (for 21.11
and later releases):
$ dpdk-pmdinfo.py /path/to/your/dpdk/drivers/librte_net_bnxt.so.22

You should get a list of supported NetXtreme nics, like:

[snipped some other drivers compiled in my application]
PMD NAME: net_bnxt
PMD HW SUPPORT:
=C2=A0Broadcom Inc. and subsidiaries (14e4) : BCM5745X NetXtreme-E RDMA

Function (16c1) (All Subdevices)
=C2=A0Broadcom Inc. and subsidiaries (14e4) : NetXtreme-C Ethernet Virtual<= br> Function (16cb) (All Subdevices)
[snipped the rest]

I hope you can find a (XXXX) corresponding to your NIC.
