ixgbe_dcb_calculate_tc_credits - This calculates the ieee traffic class credits from the configured bandwidth percentages. Credits are the smallest unit programmable into the underlying hardware. The IEEE 802.1Qaz specification do not use bandwidth groups so this is much simplified from the CEE case. @bw: bandwidth index by traffic class @refill: refill credits index by traffic class @max: max credits by traffic class @max_frame_size: maximum frame size

ixgbe_dcb_config - Struct containing DCB settings. @dcb_config: Pointer to DCB config structure

This function checks DCB rules for DCB settings. The following rules are checked:

  1. The sum of bandwidth percentages of all Bandwidth Groups must total 100%.
  2. The sum of bandwidth percentages of all Traffic Classes within a Bandwidth Group must total 100.
  3. A Traffic Class should not be set to both Link Strict Priority and Group Strict Priority.
  4. Link strict Bandwidth Groups can only have link strict traffic classes with zero bandwidth.

ixgbe_dcb_unpack_pfc_cee - Unpack dcb_config PFC info @cfg: dcb configuration to unpack into hardware consumable fields @map: user priority to traffic class map @pfc_up: u8 to store user priority PFC bitmask

This unpacks the dcb configuration PFC info which is stored per traffic class into a 8bit user priority bitmask that can be consumed by hardware routines. The priority to tc map must be updated before calling this routine to use current up-to maps.
