[ Upstream commit df60c332caf95d70f967aeace826e7e2f0847361 ]
During the stress tests, early RX adaptation handshakes can fail, such
as missing the RX_ADAPT ACK or not receiving a coefficient update before
block lock is established. Continuing to retry RX adaptation in this
state is often ineffective if the current mode selection is not viable.
Resetting the RX adaptation retry counter when an RX_ADAPT request fails
to receive ACK or a coefficient update prior to block lock, and clearing
mode_set so the next bring-up performs a fresh mode selection rather
than looping on a likely invalid configuration.

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.
