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:

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: -

The Infrastructure Entry Delete Register (IEDR) is used to delete entries stored in the KVD linear database. Currently, it is only possible to delete entries of size up to 2048. Future firmware versions will support deletion of entries of size up to 4096. Increase the size of the field so that the driver will be able to perform such deletions in the future, when required.

As explained in commit fc25996e ("mlxsw: spectrum_router: Increase scale of IPv6 nexthop groups"), each nexthop group is hashed by XOR-ing the interface indexes of all the member nexthop devices. To avoid many different nexthop groups ending up using the same key, the above commit started hashing the interface indexes themselves before they are XOR-ed. However, in cases in which there are many nexthop groups that all use the same nexthop device and only differ in the gateway IP, we can still end up in a situation in which all the groups are using the same key. This eventually leads to -EBUSY error from rhashtable during insertion. Improve the situation by also making the gateway IP part of the key. Signed-off-by:

Some boards do not have the RX_ER MII signal connected. Normally in such situation, those pins would be grounded, but then again, some boards left it electrically floating. When sending traffic to those switch ports, one can see that the N_SOFERR statistics counter is incrementing once per each packet. The user manual states for this counter that it may count the number of frames "that have the MII error input being asserted prior to or up to the SOF delimiter byte". So the switch MAC is sampling an electrically floating signal, and preventing proper traffic reception because of that. As a workaround, enable the internal weak pull-downs on the input pads for the MII control signals. This way, a floating signal would be internally tied to ground. The logic levels of signals which _are_ externally driven should not be bothered by this 40-50 KOhm internal resistor. So it is not an issue to enable the internal pull-down unconditionally, irrespective of PHY interface type (MII, RMII, RGMII, SGMII) and of board layout. Signed-off-by:
