Voon Weifeng says: ==================== net: stmmac: enable multi-vector MSI This patchset adds support for multi MSI interrupts in addition to current single common interrupt implementation. Each MSI interrupt is tied to a newly introduce interrupt service routine(ISR). Hence, each interrupt will only go through the corresponding ISR. In order to increase the efficiency, enabling multi MSI interrupt will automatically select the interrupt mode configuration INTM=1. When INTM=1, the TX/RX transfer complete signal will only asserted on corresponding sbd_perch_tx_intr_o[] or sbd_perch_rx_intr_o[] without asserting signal on the common sbd_intr_o. Hence, for each TX/RX interrupts, only the corresponding ISR will be triggered. Every vendor might have different MSI vector assignment. So, this patchset only includes multi-vector MSI assignment for Intel platform.

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.
