ixgbe: Add new support for X550 MAC's

2014-11-11T14:18:56Z

This patch will add in the new MAC defines and fit it into the switch cases throughout the driver. New functionality and enablement support will be added in following patches. Signed-off-by: Don Skidmore Signed-off-by: Jeff Kirsher

ixgbe: Make return values more direct

2014-07-26T02:58:36Z

Make return values more direct, eliminating some gotos and otherwise unneeded conditionals. This also eliminates some local variables. Also a few minor cleanups in affected code so checkpatch won't complain. Signed-off-by: Mark Rustad Tested-by: Phil Schmitt Signed-off-by: Jeff Kirsher

igb/ixgbe: remove return statements for void functions

IXGBE: Set the SW prio_tc values at initialization to the HW setting.

2013-05-21T10:14:21Z

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.

ixgbe: Use num_tcs.pg_tcs as upper limit for TC when checking based on UP

2012-07-21T23:05:28Z

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.

ixgbe: Populate the prio_tc_map in ixgbe_setup_tc

2012-07-14T21:29:19Z

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.

ixgbe: Cleanup unpacking code for DCB

2012-07-14T21:20:26Z

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.

ixgbe: Simplify logic for getting traffic class from user priority

2012-07-14T21:18:29Z

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.
