Linux kernel source tree

The Get Tx Topology AQ command (opcode 0x0418) has different read flag
requirements depending on the hardware/firmware. For E810, E822, and E823
firmware the read flag must be set, and for newer hardware (E825 and E830)
it must not be set.
This results in failure to configure Tx topology and the following warning
message during probe:
DDP package does not support Tx scheduling layers switching feature -
please update to the latest DDP package and try again
The current implementation only handles E825-C but not E830. It is
confusing as we first check ice_is_e825c() and then set the flag in the set
case. Finally, we check ice_is_e825c() again and set the flag for all other
hardware in both the set and get case.
Instead, notice that we always need the read flag for set, but only need
the read flag for get on E810, E822, and E823 firmware. Fix the logic to
check the MAC type and set the read flag in get only on the older devices
which require it.

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.
