From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>
The 58818 chips support two different checksum modes.
Host driver has to register with FW which checksum mode it
prefers to use. DPDK driver want to use "cs_all_ok_mode=1".
FW advertises the support of the different checksum modes
on per VNIC basis in the HWRM_VNIC_QCAPS response.
Driver should use HWRM_VNIC_CFG to configure the needed
checksum mode.
