[ Upstream commit 48f827d4f48f5243e37b9240029ce3f456d1f490 ] A new interrupt is triggered by resetting the DMA RX buffers. Since MSI interrupts are faster than legacy interrupts, the reset of the DMA buffers must be moved to the very end of the ISR, otherwise a new MSI interrupt will be masked by the current one.

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.
