2021-12-27net: usb: pegasus: Do not drop long Ethernet framesMatthias-Christian Ott
The D-Link DSB-650TX (2001:4002) is unable to receive Ethernet frames that are longer than 1518 octets, for example, Ethernet frames that contain 802.1Q VLAN tags. The frames are sent to the pegasus driver via USB but the driver discards them because they have the Long_pkt field set to 1 in the received status report. The function read_bulk_callback of the pegasus driver treats such received "packets" (in the terminology of the hardware) as errors but the field simply does just indicate that the Ethernet frame (MAC destination to FCS) is longer than 1518 octets. It seems that in the 1990s there was a distinction between "giant" (> 1518) and "runt" (< 64) frames and the hardware includes flags to indicate this distinction. It seems that the purpose of the distinction "giant" frames was to not allow infinitely long frames due to transmission errors and to allow hardware to have an upper limit of the frame size. However, the hardware already has such limit with its 2048 octet receive buffer and, therefore, Long_pkt is merely a convention and should not be treated as a receive error. Actually, the hardware is even able to receive Ethernet frames with 2048 octets which exceeds the claimed limit frame size limit of the driver of 1536 octets (PEGASUS_MTU).

2021-12-27net: lan966x: Fix the vlan used by host portsHoratiu Vultur
The blamed commit changed the vlan used by the host ports to be 4095 instead of 0. Because of this change the following issues are seen: - when the port is probed first it was adding an entry in the MAC table with the wrong vlan (port->pvid which is default 0) and not HOST_PVID - when the port is removed from a bridge, it was using the wrong vlan to add entries in the MAC table. It was using the old PVID and not the HOST_PVID This patch fixes this two issues by using the HOST_PVID instead of port->pvid. Fixes: 6d2c186afa5d5d ("net: lan966x: Add vlan support.")

2021-12-27phy: cadence: Sierra: Add PCIe + QSGMII PHY multilink configurationSwapnil Jakhade
Add register sequences for PCIe + QSGMII PHY multilink configuration. PHY configuration for multi-link operation is done in two steps. e.g. Consider a case for a 4 lane PHY with PCIe using 2 lanes and QSGMII other 2 lanes. Sierra PHY has 2 PLLs, viz. PLLLC and PLLLC1. So in this case, PLLLC is used for PCIe and PLLLC1 is used for QSGMII. PHY is configured in two steps as described below. [1] For first step, the register values are selected as [TYPE_PCIE][TYPE_QSGMII][ssc]. This will configure PHY registers associated for PCIe involving PLLLC registers and registers for first 2 lanes of PHY. [2] In second step, the register values are selected as [TYPE_QSGMII][TYPE_PCIE][ssc]. This will configure PHY registers associated for QSGMII involving PLLLC1 registers and registers for other 2 lanes of PHY. This completes the PHY configuration for multilink operation.

https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-next Oded writes: This tag contains habanalabs driver changes for v5.17: - Support reset-during-reset. In case the f/w notifies the driver that the f/w is going to reset the device, the driver should support that even if it is in the middle of doing another reset - Support events from f/w that arrive during device resets. These events would be ignored which is bad as critical errors would not be reported and treated by the driver. - Don't kill processes that hold the control device open during hard-reset of the device. The control device operations can't crash if done during hard-reset. And usually, only monitoring applications are using the control device, so killing them defies their purpose. - Fix handling of hwmon nodes when working with legacy f/w - Change the compute context pointer to be boolean. This pointer was abused by multiple code paths that wanted fast access to the compute context structure. - Add uapi to fetch historical errors. This is necessary as errors sometimes result in hard-reset where the user application is being terminated. - Optimize GAUDI's MMU cache invalidation. - Add support for loading the latest f/w. - Add uapi to fetch HBM replacement and pending rows information. - Multiple bug fixes to the reset code. - Multiple bug fixes for Multi-CS ioctl code. - Multiple bug fixes for wait-for-interrupt ioctl code. - Many small bug fixes and cleanups. * tag 'misc-habanalabs-next-2021-12-27' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux: (70 commits) habanalabs: support hard-reset scheduling during soft-reset habanalabs: add a lock to protect multiple reset variables habanalabs: refactor reset information variables habanalabs: handle skip multi-CS if handling not done habanalabs: add CPU-CP packet for engine core ASID cfg habanalabs: replace some -ENOTTY with -EINVAL habanalabs: fix comments according to kernel-doc habanalabs: fix endianness when reading cpld version habanalabs: change wait_for_interrupt implementation habanalabs: prevent wait if CS in multi-CS list completed habanalabs: modify cpu boot status error print habanalabs: clean MMU headers definitions habanalabs: expose soft reset sysfs nodes for inference ASIC habanalabs: sysfs support for two infineon versions habanalabs: keep control device alive during hard reset habanalabs: fix hwmon handling for legacy f/w habanalabs: add current PI value to cpu packets habanalabs: remove in_debug check in device open habanalabs: return correct clock throttling period habanalabs: wait again for multi-CS if no CS completed ...

When hotpluging policy cpu, cpu policy init will be called multiple times. Unplug CPU7 -> CPU6 -> CPU5 -> CPU4, then plug CPU4 again. In this case, devm_remap will double remap and resource allocate fail. So replace devm_remap to ioremap and release resources in cpu policy exit.

2021-12-26hwmon: (mr75203) fix wrong power-up delay valueArseny Demidov
In the file mr75203.c we have a macro named POWER_DELAY_CYCLE_256, the correct value should be 0x100. The register ip_tmr is expressed in units of IP clk cycles, in accordance with the datasheet. Typical power-up delays for Temperature Sensor are 256 cycles i.e. 0x100.
