This can be PCP or DSCP or DSCP/PCP. - default priority - DSCP: this configuration is shared between the ports both at ingress and egress. v1->v2: - fix whitespace between app_itr and .priority in patch 2 - simplify function lan966x_dcb_ieee_setapp by removing goto and use returns instead - remove check against 0 Horatiu Vultur (7): net: lan966x: Add registers to configure PCP, DEI, DSCP net: lan966x: Add support for offloading pcp table net: lan966x: Add support for apptrust net: lan966x: Add support for offloading dscp table net: lan966x: Add support for offloading default prio net: lan966x: Add support for PCP rewrite net: lan966x: Add support for DSCP rewrite .../net/ethernet/microchip/lan966x/Kconfig | 11 + .../net/ethernet/microchip/lan966x/Makefile | 1 + .../ethernet/microchip/lan966x/lan966x_dcb.c | 365 ++++++++++++++++++ .../ethernet/microchip/lan966x/lan966x_main.c | 2 + .../ethernet/microchip/lan966x/lan966x_main.h | 57 +++ .../ethernet/microchip/lan966x/lan966x_port.c | 149 +++++++ .../ethernet/microchip/lan966x/lan966x_regs.h | 132 +++++++ 7 files changed, 717 insertions(+) create mode 100644 drivers/net/ethernet/microchip/lan966x/lan966x_dcb.c -- 2.38.0
