Patrisious Haddad 465d6b42f1 RDMA/core: Add support to set privileged QKEY parameter 
Add netlink command that enables/disables privileged QKEY by default.

It is disabled by default, since according to IB spec only privileged
users are allowed to use privileged QKEY.
According to the IB specification rel-1.6, section 3.5.3:
"QKEYs with the most significant bit set are considered controlled
QKEYs, and a HCA does not allow a consumer to arbitrarily specify a
controlled QKEY."

Using rdma tool,
$rdma system set privileged-qkey on

When enabled non-privileged users would be able to use
controlled QKEYs which are considered privileged.

Using rdma tool,
$rdma system set privileged-qkey off

When disabled only privileged users would be able to use
controlled QKEYs.

You can also use the command below to check the parameter state:
$rdma system show
netns shared privileged-qkey off copy-on-fork on
