We currently hard code the priority in the 8021q tag to 3 for FCoE traffic. The vast majority of the time this is fine but if the priority is something else besides 3, any VLAN ID comparison either in the non-offload path or offload path will fail and cause dropped frames where none are expected. Change the behavior so that the driver default is 3 if we do not get any DCBX convergence. If DCBX does converge, then set the FIP/FCoE priority in the following manner: 1. If the qedf_default_prio modparam is set use that 2. If the DCBX FCoE priority is not in range (0..7) use 3 3. Use the DCBX FCoE priority we get in the driver's DCBX handler Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
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.
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.
