net/bnxt: add new Rx checksum mode

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.
