Amit Cohen 0a66e5582b mlxsw: spectrum_ptp: Add missing verification before pushing Tx header
Tx header should be pushed for each packet which is transmitted via
Spectrum ASICs. The cited commit moved the call to skb_cow_head() from
mlxsw_sp_port_xmit() to functions which handle Tx header.

In case that mlxsw_sp->ptp_ops->txhdr_construct() is used to handle Tx
header, and txhdr_construct() is mlxsw_sp_ptp_txhdr_construct(), there is
no call for skb_cow_head() before pushing Tx header size to SKB. This flow
is relevant for Spectrum-1 and Spectrum-4, for PTP packets.

Add the missing call to skb_cow_head() to make sure that there is both
enough room to push the Tx header and that the SKB header is not cloned and
can be modified.

An additional set will be sent to net-next to centralize the handling of
the Tx header by pushing it to every packet just before transmission.

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 reStructuredText 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.
