Jarod Wilson 751da2a69b bonding: fix accounting of active ports in 3ad 
As of 7bb11dc9f5 and 0622cab034, bond slaves in a 3ad bond are not
removed from the aggregator when they are down, and the active slave count
is NOT equal to number of ports in the aggregator, but rather the number
of ports in the aggregator that are still enabled. The sysfs spew for
bonding_show_ad_num_ports() has a comment that says "Show number of active
802.3ad ports.", but it's currently showing total number of ports, both
active and inactive. Remedy it by using the same logic introduced in
0622cab034 in __bond_3ad_get_active_agg_info(), so sysfs, procfs and
netlink all report the number of active ports. Note that this means that
IFLA_BOND_AD_INFO_NUM_PORTS really means NUM_ACTIVE_PORTS instead of
NUM_PORTS, and thus perhaps should be renamed for clarity.

Lightly tested on a dual i40e lacp bond, simulating link downs with an ip
link set dev <slave2> down, was able to produce the state where I could
see both in the same aggregator, but a number of ports count of 1.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
