The __IGC_PTP_TX_IN_PROGRESS flag indicates we have a pending Tx timestamp. In some places, instead of checking that flag, we check adapter->ptp_tx_skb. This patch fixes those places to use the flag. Quick note about igc_ptp_tx_hwtstamp() change: when that function is called, adapter->ptp_tx_skb is expected to be valid always so we WARN_ON_ONCE() in case it is not. Quick note about igc_ptp_suspend() change: when suspending, we don't really need to check if there is a pending timestamp. We can simply clear it unconditionally.

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.
