[dpdk-dev] [PATCH 7/9] net/bnxt: fix check for PTP support in FW

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>

On Thor, driver must use HWRM to access the timestamp information.
Driver should not advertise PTP support to application
if PTP information is not accessible via HWRM commands.

Fixes: 6cbd89f9f3d8 ("net/bnxt: support PTP for Thor")
