[ Upstream commite8b51a1a15] The driver does not support PTP on these older chips and it is assuming that firmware on these older chips will not return the PORT_MAC_PTP_QCFG_RESP_FLAGS_HWRM_ACCESS flag in __bnxt_hwrm_ptp_qcfg(), causing the function to abort quietly. But newer firmware now sets this flag and so __bnxt_hwrm_ptp_qcfg() will proceed further. Eventually it will fail in bnxt_ptp_init() -> bnxt_map_ptp_regs() because there is no code to support the older chips. The driver will then complain: "PTP initialization failed.\n" Fix it so that we abort quietly earlier without going through the unnecessary steps and alarming the user with the warning log.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
