[ Upstream commit51afe9026d] In scenarios where multiple errors have occurred for a SQ before SW starts handling error interrupt, SQ_CTX[OP_INT] may get overwritten leading to NIX_LF_SQ_OP_INT returning incorrect value. To workaround this read LMT, MNQ and SQ individual error status registers to determine the cause of error.

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.
