Akihiko Odaki 28e96556ba igb: Allocate MSI-X vector when testing 
Without this change, the interrupt test fail with MSI-X environment:

$ sudo ethtool -t enp0s2 offline
[   43.921783] igb 0000:00:02.0: offline testing starting
[   44.855824] igb 0000:00:02.0 enp0s2: igb: enp0s2 NIC Link is Down
[   44.961249] igb 0000:00:02.0 enp0s2: igb: enp0s2 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
[   51.272202] igb 0000:00:02.0: testing shared interrupt
[   56.996975] igb 0000:00:02.0 enp0s2: igb: enp0s2 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
The test result is FAIL
The test extra info:
Register test  (offline)	 0
Eeprom test    (offline)	 0
Interrupt test (offline)	 4
Loopback test  (offline)	 0
Link test   (on/offline)	 0

Here, "4" means an expected interrupt was not delivered.

To fix this, route IRQs correctly to the first MSI-X vector by setting
IVAR_MISC. Also, set bit 0 of EIMS so that the vector will not be
masked. The interrupt test now runs properly with this change:

$ sudo ethtool -t enp0s2 offline
[   42.762985] igb 0000:00:02.0: offline testing starting
[   50.141967] igb 0000:00:02.0: testing shared interrupt
[   56.163957] igb 0000:00:02.0 enp0s2: igb: enp0s2 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
The test result is PASS
The test extra info:
Register test  (offline)	 0
Eeprom test    (offline)	 0
Interrupt test (offline)	 0
Loopback test  (offline)	 0
Link test   (on/offline)	 0

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.
