Now mv88e6xxx does not enable its ports at setup itself and let the DSA core handle this, unused ports are disabled without being powered on first. While that is expected, the SERDES powering code was assuming that a port was already set up before powering it down, resulting in freeing an unused IRQ. The patch fixes this assumption.

This is a follow-up patch for commit 7a3007d2 ("net: dsa: mv88e6xxx: fully support SERDES on Topaz family"). Since .port_set_cmode is only called from mv88e6xxx_port_setup_mac and mv88e6xxx_phylink_mac_config, it is fine to keep this "make writable" code private to the mv88e6341_port_set_cmode implementation, instead of adding yet another operation to the switch info structure.

This is a follow-up patch for commit 17deaf5c ("net: dsa: mv88e6xxx: create serdes_get_lane chip operation"). The .serdes_get_lane implementations access the CMODE of a port, even though it is cached at the moment, it is safer to call them after the mutex is locked, not before. At the same time, check for an eventual error and return IRQ_DONE, instead of blindly ignoring it. Signed-off-by:

The current loopback mode is to add 0x1F to the SMAC address as the DMAC address and enable the promiscuous mode. However, if the VF address is the same as the DMAC address, the loopback test fails. Loopback can be enabled in three places: SSU, MAC, and serdes. By default, SSU loopback is enabled, so if the SMAC and the DMAC are the same, the packets are looped back in the SSU. If SSU loopback is disabled, packets can reach MAC even if SMAC is the same as DMAC. Therefore, this patch disables the SSU loopback before the loopback test. In this way, the SMAC and DMAC can be the same, and the promiscuous mode does not need to be enabled. And this is not valid in version 0x20. This patch also uses a macro to replace 0x1F.

Starting with firmware version MC10.18.0, we have support for L2 flow control. Asymmetrical configuration (Rx or Tx only) is supported, but not pause frame autonegotioation. Pause frame configuration is done via ethtool. By default, we start with flow control enabled on both Rx and Tx. Changes are propagated to hardware through firmware commands, using two flags (PAUSE, ASYM_PAUSE) to specify Rx and Tx pause configuration, as follows: PAUSE | ASYM_PAUSE | Rx pause | Tx pause ---------------------------------------- 0 | 0 | disabled | disabled 0 | 1 | disabled | enabled 1 | 0 | enabled | enabled 1 | 1 | enabled | disabled The hardware can automatically send pause frames when the number of buffers in the pool goes below a predefined threshold. Due to this, flow control is incompatible with Rx frame queue taildrop (both mechanisms target the case when processing of ingress frames can't keep up with the Rx rate; for large frames, the number of buffers in the pool may never get low enough to trigger pause frames as long as taildrop is enabled). So we set pause frame generation and Rx FQ taildrop as mutually exclusive. Signed-off-by:

We only support fixed-link for now, so there is no point in offering users the option to change link settings via ethtool. Functionally there is no change, since firmware prevents us from changing link parameters anyway. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Various updates Patch #1 from Amit removes 56G speed support. The reasons for this are detailed in the commit message. Patch #2 from Shalom ensures that the hardware does not auto negotiate the number of used lanes. For example, if a four lane port supports 100G over both two and four lanes, it will not advertise the two lane link mode. Patch #3 bumps the firmware version supported by the driver. Patch #4 from Petr adds ethtool counters to help debug the internal PTP implementation in mlxsw. I copied Richard on this patch in case he has comments. ==================== Signed-off-by: -

On Spectrum-1, timestamped PTP packets and the corresponding timestamps need to be kept in caches until both are available, at which point they are matched up and packets forwarded as appropriate. However, not all packets will ever see their timestamp, and not all timestamps will ever see their packet. It is necessary to dispose of such abandoned entries, so a garbage collector was introduced in commit 5d23e415 ("mlxsw: spectrum: PTP: Garbage-collect unmatched entries"). If these GC events happen often, it is a sign of a problem. However because this whole mechanism is taking place behind the scenes, there is no direct way to determine whether garbage collection took place. Therefore to fix this, on Spectrum-1 only, expose four artificial ethtool counters for the GC events: GCd timestamps and packets, in TX and RX directions.

After 50G-1-lane and 100G-2-lanes link modes were introduced, the driver is facing situations in which the hardware auto negotiates not only on speed and type, but also on number of lanes. Prevent auto negotiation on number of lanes by allowing only port speeds that can be supported on a given port according to its width. Signed-off-by:

Commit 275e928f ("mlxsw: spectrum: Prevent force of 56G") prevented the driver from setting a speed of 56G when auto-negotiation is off. This is the only speed supported by mlxsw that cannot be set when auto-negotiation is off, which makes it difficult to write generic tests. Further, the speed is not supported by newer ASICs such as Spectrum-2 and to the best of our knowledge it is not used by current users. Therefore, remove 56G support from mlxsw. Signed-off-by:

Some ethernet drivers may call phy_start() and phy_stop() from ndo_open() and ndo_close() respectively. When network cable is unconnected, and operate like below: step 1: ifconfig ethX up -> ndo_open -> phy_start ->start autoneg, and phy is no link. step 2: ifconfig ethX down -> ndo_close -> phy_stop -> just stop phy state machine. This patch forces phy suspend even phydev->link is off. Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-08-26 This series contains updates to ice driver only. Usha fixes the statistics reported on 4 port NICs which were reporting the incorrect statistics due to using the incorrect port identifier. Victor fixes an issue when trying to traverse to the first node of a requested layer by adding a sibling head pointer for each layer per traffic class. Anirudh cleans up the locking and logic for enabling and disabling VSI's to make it more consistent. Updates the driver to do dynamic allocation of queue management bitmaps and arrays, rather than statically allocating them which consumes more memory than required. Refactor the logic in ice_ena_msix_range() for clarity and add additional checks for when requested resources exceed what is available. Jesse updates the debugging print statements to make it more useful when dealing with link and PHY related issues. Krzysztof adds a local variable to the VSI rebuild path to improve readability. Akeem limits the reporting of MDD events from VFs so that the kernel log is not clogged up with MDD events which are duplicate or potentially false positives. Fixed a reset issue that would result in the system getting into a state that could only be resolved by a reboot by testing if the VF is in a disabled state during a reset. Michal adds a check to avoid trying to access memory that has not be allocated by checking the number of queue pairs. Jake fixes a static analysis warning due to a cast of a u8 to unsigned long, so just update ice_is_tc_ena() to take a unsigned long so that a cast is not necessary. Colin Ian King fixes a potential infinite loop where a u8 is being compared to an int. Maciej refactors the queue handling functions that work on queue arrays so that the logic can be done for a single queue. Paul adds support for VFs to enable and disable single queues. Henry fixed the order of operations in ice_remove() which was trying to use adminq operations that were already disabled. ==================== Signed-off-by: -
