Ronak Doshi a6ddbf9ae7 vmxnet3: update MTU after device quiesce 
commit 43f0999af0 upstream.

Currently, when device mtu is updated, vmxnet3 updates netdev mtu, quiesces
the device and then reactivates it for the ESXi to know about the new mtu.
So, technically the OS stack can start using the new mtu before ESXi knows
about the new mtu.

This can lead to issues for TSO packets which use mss as per the new mtu
configured. This patch fixes this issue by moving the mtu write after
device quiesce.

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.
