Dragos Tatulea ee0e9b2c4b IB/IPoIB: Fix queue count inconsistency for PKEY child interfaces 
[ Upstream commit dbc94a0fb8 ]

There are 2 ways to create IPoIB PKEY child interfaces:
1) Writing a PKEY to /sys/class/net/<ib parent interface>/create_child.
2) Using netlink with iproute.

While with sysfs the child interface has the same number of tx and
rx queues as the parent, with netlink there will always be 1 tx
and 1 rx queue for the child interface. That's because the
get_num_tx/rx_queues() netlink ops are missing and the default value
of 1 is taken for the number of queues (in rtnl_create_link()).

This change adds the get_num_tx/rx_queues() ops which allows for
interfaces with multiple queues to be created over netlink. This
constant only represents the max number of tx and rx queues on that
net device.

Fixes: 9baa0b0364 ("IB/ipoib: Add rtnl_link_ops support")

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.
