Only QMAP endpoints should be configured to find a pad size field within packet headers. They are found in the first byte of the QMAP header (and the hardware fills only the 6 bits in that byte that constitute the pad_len field). The RMNet driver assumes the pad_len field is valid for received packets, so we want to ensure the pad_len field is filled in that case. That driver also assumes the length in the QMAP header includes the pad bytes. The RMNet driver does *not* pad the packets it sends, so the pad_len field can be ignored. Fix ipa_endpoint_init_hdr_ext() so it only marks the pad field offset valid for QMAP RX endpoints, and in that case indicates that the length field in the header includes the pad bytes.

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.
