[ Upstream commit a9b952d267e59a3b405e644930f46d252cea7122 ]
MTU changes may affect the number of IRQs so we must call
bnxt_close_nic()/bnxt_open_nic() with the irq_re_init parameter
set to true. The reason is that a larger MTU may require
aggregation rings not needed with smaller MTU. We may not be
able to allocate the required number of aggregation rings and
so we reduce the number of channels which will change the number
of IRQs. Without this patch, it may crash eventually in
pci_disable_msix() when the IRQs are not properly unwound.

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.
