Ong Boon Leong b42446b9b3 stmmac: intel: add support for multi-vector msi and msi-x
Intel mgbe controller supports multi-vector interrupts:
msi_rx_vec	0,2,4,6,8,10,12,14
msi_tx_vec	1,3,5,7,9,11,13,15
msi_sfty_ue_vec	26
msi_sfty_ce_vec	27
msi_lpi_vec	28
msi_mac_vec	29

During probe(), the driver will starts with request allocation for
multi-vector interrupts. If it fails, then it will automatically fallback
to request allocation for single interrupts.

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.
