Add parser entries for different IPv4 IHL values. Each entry will set the L4 header offset according to the IPv4 IHL field. L3 header offset will set during the parsing of the IPv4 protocol. Because of missed parser support for IP header length > 20, RX IPv4 checksum HW offload fails and skb->ip_summed set to CHECKSUM_NONE(checksum done by Network stack). This patch adds RX IPv4 checksum HW offload capability for frames with IP header length > 20. v1 --> v2 - Improve commit message.

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.
