2018-04-27net: intel: Cleanup the copyright/license headersJeff Kirsher
After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

2018-01-12ixgbe: Fix kernel-doc format warningsTony Nguyen
Recent checks added for formatting kernel-doc comments are causing warnings if W= is run with a non-zero value. This patch fixes function comments to resolve warnings when W=1 is used.

2016-04-25ixgbe: use BIT() macroJacob Keller
Several areas of ixgbe were written before widespread usage of the BIT(n) macro. With the impending release of GCC 6 and its associated new warnings, some usages such as (1 << 31) have been noted within the ixgbe driver source. Fix these wholesale and prevent future issues by simply using BIT macro instead of hand coded bit shifts. Also fix a few shifts that are shifting values into place by using the 'u' prefix to indicate unsigned. It doesn't strictly matter in these cases because we're not shifting by too large a value, but these are all unsigned values and should be indicated as such.

2016-04-07ixgbe: Add support for x550em_a 10G MAC typeMark Rustad
Add support for x550em_a 10G MAC type to the ixgbe driver. The new MAC includes new firmware commands that need to be used to control PHY and IOSF access, so that support is also added. The interface supported is a native SFP+ interface.

2016-01-08ixgbe: Fill at least min credits to a TC credit refillsVasu Dev
Currently credit_refill and credit_max could be zero for a TC and that is causing Tx hang for CEE mode configuration, so to fix that have at min credit assigned to a TC and that is as what IEEE mode already does.

Set the SW prio_tc values at initialization to the HW setting. Setting the SW prio_tc default values to be the HW setting by reading the rtrup2tc register. For any TC change we need to reset the device. This will remove the need to reset the device at the first time we call ixgbe_dcbnl_ieee_setets.

2012-07-21ixgbe: Use num_tcs.pg_tcs as upper limit for TC when checking based on UPAlexander Duyck
This change makes it so the function ixgbe_dcb_get_tc_from_up will use the num_tcs.pg_tcs to determine the starting value for determining a traffic class based on a user priority. The main motivation for this change is to address possible bad configurations in which more TCs worth of data are populated then there are actual TCs. By limiting this value we can at least make certain we are not providing a map with values that are out of range. As a result any user priorities that are setup in the configuration with a traffic class mapping higher than what the hardware supports will be reported as being on TC 0.

2012-07-14ixgbe: Populate the prio_tc_map in ixgbe_setup_tcAlexander Duyck
There were cases where the prio_tc_map was not populated when we were calling open. This will result in us incorrectly configuring the traffic classes when DCB is enabled. In order to correct this I have updated the code so that we now populate the values prior to allocating the q_vectors and calling ixgbe_open.

2012-07-14ixgbe: Cleanup unpacking code for DCBAlexander Duyck
This is meant to be a generic clean-up of the remaining functions for unpacking data from the DCB structures. The only real changes are: replaced the variable i with tc for functions that were looping through the traffic classes, and added a pointer for tc_class instead of path since that way we only need to pull the pointer once instead of once per loop.

2012-07-14ixgbe: Simplify logic for getting traffic class from user priorityAlexander Duyck
This patch is meant to help simplify the logic for getting traffic classes from user priorities. To do this I am adding a function named ixgbe_dcb_get_tc_from_up that will go through the traffic classes in reverse order in order to determine which traffic class contains a bit for a given user priority. Adding a declaration for this new function to the header so that we have a centralized means for sorting out traffic classes belonging to features such as FCoE.
