2023-08-21mtd: rawnand: mpc5121: Use helper function devm_clk_get_enabled()Li Zetao
Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be replaced by devm_clk_get_enabled() when driver enables (and possibly prepares) the clocks for the whole lifetime of the device. Moreover, it is no longer necessary to unprepare and disable the clocks explicitly.

It is unknown whether asymetric pause is supported at all speeds. The CPU port uses MII/GMII/RGMII/REVMII by hardware pin strapping, and support speeds specific to each, with full duplex only supported in some modes. Flow control may be supported again by hardware pin strapping, and theoretically is readable through a register but no information is given in the datasheet for that.

Also support alias IP for the MACsec device, as long as we don't have more ips than what the gid table can hold.

2023-08-20RDMA/mlx5: Implement MACsec gid addition and deletionPatrisious Haddad
Handle MACsec IP ambiguity issue, since mlx5 hw can't support programming both the MACsec and the physical gid when they have the same IP address, because it wouldn't know to whom to steer the traffic. Hence in such case we delete the physical gid from the hw gid table, which would then cause all traffic sent over it to fail, and we'll only be able to send traffic over the MACsec gid.

2023-08-20macsec: add functions to get macsec real netdevice and check offloadPatrisious Haddad
Given a macsec net_device add two functions to return the real net_device for that device, and check if that macsec device is offloaded or not. This is needed for auxiliary drivers that implement MACsec offload, but have flows which are triggered over the macsec net_device, this allows the drivers in such cases to verify if the device is offloaded or not, and to access the real device of that macsec device, which would belong to the driver, and would be needed for the offload procedure.

2023-08-19net: phy: Fix deadlocking in phy_error() invocationSerge Semin
Since commit 91a7cda1f4b8 ("net: phy: Fix race condition on link status change") all the phy_error() method invocations have been causing the nested-mutex-lock deadlock because it's normally done in the PHY-driver threaded IRQ handlers which since that change have been called with the phydev->lock mutex held. Here is the calls thread: IRQ: phy_interrupt() +-> mutex_lock(&phydev->lock); <--------------------+ drv->handle_interrupt() | Deadlock due +-> ERROR: phy_error() + to the nested +-> phy_process_error() | mutex lock +-> mutex_lock(&phydev->lock); <-+ phydev->state = PHY_ERROR; mutex_unlock(&phydev->lock); mutex_unlock(&phydev->lock); The problem can be easily reproduced just by calling phy_error() from any PHY-device threaded interrupt handler. Fix it by dropping the phydev->lock mutex lock from the phy_process_error() method and printing a nasty error message to the system log if the mutex isn't held in the caller execution context. Note for the fix to work correctly in the PHY-subsystem itself the phydev->lock mutex locking must be added to the phy_error_precise() function.

2023-08-19net: sfp: handle 100G/25G active optical cables in sfp_parse_supportJosua Mayer
Handle extended compliance code 0x1 (SFF8024_ECC_100G_25GAUI_C2M_AOC) for active optical cables supporting 25G and 100G speeds. Since the specification makes no statement about transmitter range, and as the specific sfp module that had been tested features only 2m fiber - short-range (SR) modes are selected. The 100G speed is irrelevant because it would require multiple fibers / multiple SFP28 modules combined under one netdev. sfp-bus.c only handles a single module per netdev, so only 25Gbps modes are selected. sfp_parse_support already handles SFF8024_ECC_100GBASE_SR4_25GBASE_SR with compatible properties, however that entry is a contradiction in itself since with SFP(28) 100GBASE_SR4 is impossible - that would likely be a mode for qsfp modules only. Add a case for SFF8024_ECC_100G_25GAUI_C2M_AOC selecting 25gbase-r interface mode and 25000baseSR link mode. Also enforce SFP28 bitrate limits on the values read from sfp eeprom as requested by Russell King. Tested with fs.com S28-AO02 AOC SFP28 module.
