Although not specified in 8021Qaz spec, it could be useful to enable drivers whose HW supports setting a rate limit for an ETS TC. This patch adds this optional attribute to DCB netlink. To use it, drivers should implement and register the callbacks ieee_setmaxrate and ieee_getmaxrate. The units are 64 bits long and specified in Kbps to enable usage over both slow and very fast networks. Signed-off-by:

Since vlan egress map is only good for tagged traffic, need to have other mapping to be used by untagged traffic. For that, the driver uses sch_mqprio mapping. This mapping could be set by using tc tool from iproute2 package. Mapped UP will be used by the HW for QoS purposes, but won't go out on the wire. Signed-off-by:

Instead of relying on HW to change schedule queue by UP, schedule queue is fixed for a tx_ring, and UP in WQE is ignored in this aspect. This resolves two issues with untagged traffic: 1. untagged traffic has no UP in packet which is needed for QoS. The change above allows setting the schedule queue (and by that the UP) of such a stream. 2. BlueFlame uses the same field used by vlan tag. So forcing UP from QPC allows using BF for untagged but prioritized traffic. In old firmware that force UP is not supported, untagged traffic will not subject to QoS. Because UP is set by QP, need to always have a tx ring per UP, even if pfcrx module paramter is false. Signed-off-by:

If a specific clk_csr value is passed from the platform this means that the CSR Clock Range selection cannot be changed at run-time and it is fixed (as reported in the driver documentation). Viceversa the driver will try to set the MDC clock dynamically according to the actual clock input. Signed-off-by:

The CSR Clock Range has been reworked and new macros has been added in the platform header to allow the CSR Clock Range selection in the GMII Address Register. The previous work didn't add the other fields that can be used to achieve MDC clock of frequency higher than the IEEE 802.3 specified frequency limit of 2.5 MHz and program a clock divider of lower value. On such platforms, these are used indeed so this patch adds them. Signed-off-by:

This patch re-works the internal GMAC DMA parameters passed from the platform. In the past, we only passed the pbl but, with new core, other parameters can be passed and are mandatory on some platforms. New parameters are documented in stmmac.txt because this patch has an impact for many platforms. Signed-off-by:

The patch adds the macros to be used for MDC clock selection. The MDC clock frequency is based on scaled system clock, and has to be confined to a range of 1-2.5 MHz. Based on the input CSR clock, the scaling factor has to be selected. The platform specific code will provide the default value of this scaling factor, based on the input CSR clock. There is an option to set MDC clock higher than the IEEE 802.3 specified frequency limit of 2.5 MHz. This applies for the interfacing chips that support higher MDC clocks. The resultant higher clock of 12.5 MHz requires additional Macros to be defined for the clock divider corresponding to the to the following selection. ----------------------------------------- Selection MDC Clock ----------------------------------------- 1000 clk_csr_i/4 1001 clk_csr_i/6 1010 clk_csr_i/8 1011 clk_csr_i/10 1100 clk_csr_i/12 1101 clk_csr_i/14 1110 clk_csr_i/16 1111 clk_csr_i/18 This support has to be added both in the include file, as well as driver. The driver need to program the registers based on the interfacing chips. This would be more board specific information and needs to be passed through the platform code to the driver. This work would be carried out in the future patch set release. Signed-off-by:

This patch sanities the RX coe and adds the Type-1 Rx checksum offload engine (COE). So the RX COE can be passed through the platform but can be fixed at run-time in case of the core has the HW capability register. Also to support the Type-1 Rx COE the driver must append the HW checksum at the end of payload in case the Rx checksum engine was used to offload the HW checksum. This v2 version also fixes the IPC that has to be enabled and verified. Signed-off-by:

This patch explicitly defines the CSUM offload engine type which need (not mandatory) to be passed from the platform code. STMMAC core supports two check sum offload engine types- Type-1 & Type-2. Also, there are STMMAC cores that do not have the check sum offload capabilities. The behaviour of Type-1 & Type-2 cores related to provision of checksum increases the packet length for Type-1 cores by 2, as the checksum is appended at the end of data packet and the same is made accountable in the DMA status. The STMMAC cores beyond Version-3.5 provide HW interface registers which allows the user to read the HW capabilities, while to support the previous cores the information related to HW capabilities has to be provided from the platform code. The Type-1 cores which do not have the HW register interface need this information. This patch also updates the driver's doc. Signed-off-by:

As stmmac mdio bus name prefix is hardcoded in the driver, this allows only phys on stmmac mdio buses to connect, however stmmac should allow phys on other mdio buses too. This patch adds new variable phy_bus_name to plat_stmmacenet_data struct to let the BSP decide which phy bus to be used by stmmac driver. A typical use-case is to have generic MDIO buses like mdio-gpio on top of stmmac. Signed-off-by:

This patch removes busy wait in tx/rx cleanup. bnad_cb_tx_cleanup() and bnad_cb_rx_cleanup() functions are called from irq context, and currently they do busy wait for the in-flight transmit or the currently executing napi polling routine to complete. To fix the issue, we create a workqueue to defer tx & rx cleanup processing, an in the tx rx cleanup handler, we will wait respective in flight processing to complete, before freeing the buffers.
