While IEEE and CEE use the same structure to store apps, the selector
and priority fields for both are different. Only the priority field is
explained, add documentation explaining how the selector field differs
for both.
cgdcbxd code shows an example of how selector fields differ.

As specified in 802.1Qau spec. Add this optional attribute to the
DCB netlink layer. To allow for application to use the new attribute,
NIC drivers should implement and register the callbacks ieee_getqcn,
ieee_setqcn and ieee_getqcnstats.
The QCN attribute holds a set of parameters for management, and
a set of statistics to provide informative data on Congestion-Control
defined by this spec.

Current explanation of dcb_app->priority is wrong. It says priority is
expected to be a 3-bit unsigned integer which is only true when working with
DCBx-IEEE. Use of dcb_app->priority by DCBx-CEE expects it to be 802.1p user
priority bitmap. Updated accordingly
This affects the cxgb4 driver, but I will post those changes as part of a
larger changeset shortly.
Fixes: 3e29027af4 ("dcbnl: add support for ieee8021Qaz attributes")
