Conversion to devm_clk_get_optional() makes it explicit that clocks are optional. This change allows to handle deferred probe in case clocks are defined, but not yet probed. Due to above changes bail out in error case. While here, check potential error when enable main clock. Signed-off-by:

A barrier is needed here to ensure that rtl_tx sees the descriptor changes (DescOwn set) before the updated tp->cur_tx value. Else it may wrongly assume that the transfer has been finished already. For this purpose smp_wmb() is sufficient. No separate barrier is needed for ordering the descriptor changes with the MMIO doorbell write. The needed barrier is included in the non-relaxed writel() used by rtl8169_doorbell(). Signed-off-by:

In notify HW (ring doorbell) flow, we set the bit to request a completion on the TX descriptor. When doing so, we should not unset other bits in the same byte. Currently, this does not fix a real issue, as we still don't have a flow where both MLX5_WQE_CTRL_CQ_UPDATE and any adjacent bit are set together.

Currently the SA handle is created and managed as part of the common code for different IPsec supporting HW, this handle is passed to HW to be used on Rx to identify the SA handle that was used to return the xfrm state to stack. The above implementation pose a limitation on managing this handle. Refactor by moving management of this field to the specific HW code. Downstream patches will introduce the Connect-X support for IPsec that will use this handle differently than current implementation. Signed-off-by:

Currently the FPGA IPsec is the only hw implementation of the IPsec acceleration api, and so the mlx5_accel_esp_create_hw_context was wrongly made to suit this HW api, among other in its parameter list and some of its parameter endianness. This implementation might not be suitable for different HW. Refactor by group and pass all function arguments of mlx5_accel_esp_create_hw_context in common mlx5_accel_esp_xfrm_attrs struct field of mlx5_accel_esp_xfrm struct and correct the endianness according to the HW being called.

The cited commit relies on include <net/geneve.h> being included implicitly prior to include "en_accel/en_accel.h". This mandates that all files that needs to include en_accel.h to redantantly include net/geneve.h. Include net/geneve.h explicitly at "en_accel/en_accel.h" to avoid undesired constrain as above.

Currently the IPsec acceleration capability function is also used at IPsec fpga capable device code. This could cause a future bug as the acceleration layer is agnostic to the device implementing its API. Fix by using the IPsec FPGA capability function instead of acceleration layer capability function in case of FPGA IPsec only related operations. Downstream patches will add support for Connect-X IPsec, this can avoid a future bug. Signed-off-by:

Andrew Lunn says: ==================== FEC MDIO speedups This patchset gives a number of speedups for MDIO with the FEC. Replacing interrupt driven with polled IO brings a big speedup due to the overheads of interrupts compared to the short time interval. Clocking the bus faster, when the MDIO targets supports it, can double the transfer rate. And suppressing the preamble, if devices support it, makes each transaction faster. By default the MDIO clock remains 2.5MHz and preables are used. But these can now be controlled from the device tree. Since these are generic properties applicable to more than just FEC, these have been added to the generic MDIO binding documentation. v2: readl_poll_timeout() Add patches to set bus frequency and preamble disable v3: Add Reviewed tags uS->us readl_poll_timeout_atomic() Extend DT binding documentation ==================== Acked-by:

An MDIO transaction normally starts with 32 1s as a preamble. However not all devices requires such a preamble. Add a device tree property which allows the preamble to be suppressed. This will half the size of the MDIO transaction, allowing faster transactions. But it should only be used when all devices on the bus support suppressed preamble. Suggested-by:

MDIO busses typically operate at 2.5MHz. However many devices can operate at faster speeds. This then allows more MDIO transactions per second, useful for Ethernet switch statistics, or Ethernet PHY TDR data. Allow the bus speed to be configured, using the standard "clock-frequency" property, which i2c busses use to indicate the bus speed. Before using this property, ensure all devices on the bus do actually support the requested clock speed. Suggested-by:

Measurements of the MDIO bus have shown that driving the MDIO bus using interrupts is slow. Back to back MDIO transactions take about 90us, with 25us spent performing the transaction, and the remainder of the time the bus is idle. Replacing the completion interrupt with polled IO results in back to back transactions of 40us. The polling loop waiting for the hardware to complete the transaction takes around 28us. Which suggests interrupt handling has an overhead of 50us, and polled IO nearly halves this overhead, and doubles the MDIO performance. Suggested-by:

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-04-19 This series contains updates to e1000e and igc only. Sasha adds new device IDs supported by the igc driver. Vitaly fixes the S0ix entry and exit flows in e1000e for TGP and newer MAC types when a cable is connected. Andre has the remaining changes in the series, starting with cleanup of the igc driver of duplicate code. Added a check for IGC_MAC_STATE_SRC_ADDR flag which is unsupported for MAC filters in igc. Cleaned up the return values for igc_add_mac_filter(), where the return value was not being used, so update the function to only return success or failure. Fix the return value of igc_uc_unsync() as well. Refactor the igc driver in several functions to help reduce the convoluted logic and simplify the driver filtering mechanisms. Improve the MAC address checks when adding a MAC filter. Lastly, improve the log messages related to MAC address filtering to ease debugging. ==================== Signed-off-by: -
