ice driver will not work with the card you have listed. It is for an Intel NIC.
Support for BCM5708 was added in 2019 in the Broadcom bnxt PMD.
You can either use the 19.11 - an LTS version. But that is not
maintained anymore.
You can use the 22.11 release which is still maintained. Refer to the
DPDK roadmap
for EOL releases.
