The existing code is using RSS profile to determine IPV4/IPV6 GSO type on all chips older than 5760X. This won't work on 5750X chips that may be using modified RSS profiles. This commit from 2018 has updated the driver to not use RSS profile for HW GRO packets on newer chips:50f011b63d("bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.") However, a recent commit to add support for the newest 5760X chip broke the logic. If the GRO packet needs to be re-segmented by the stack, the wrong GSO type will cause the packet to be dropped. Fix it to only use RSS profile to determine GSO type on the oldest 5730X/5740X chips which cannot use the new method and is safe to use the RSS profiles. Also fix the L3/L4 hash type for RX packets by not using the RSS profile for the same reason. Use the ITYPE field in the RX completion to determine L3/L4 hash types correctly.

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.
