If wol state of phy hardware is enabled after reset, phy_ethtool_get_wol() returns that wol.wolopts is true. However, since net_device.wol_enabled is zero and this doesn't apply wol state until calling ethtool_set_wol(), so mdio_bus_phy_may_suspend() returns true, that is, it's in a state where phy can suspend even though wol state is enabled. In this inconsistency, phy_suspend() returns -EBUSY, and at last, suspend sequence fails with the following message: dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x58 returns -16 PM: Device 65000000.ethernet-ffffffff:01 failed to suspend: error -16 PM: Some devices failed to suspend, or early wake event detected In order to fix the above issue, this patch forces to set initial wol state to disabled as default.

Merge tag 'linux-can-next-for-4.21-20181128' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== This is a pull request for net-next/master consisting of 18 patches. The first patch is by Colin Ian King and fixes the spelling in the ucan driver. The next three patches target the xilinx driver. YueHaibing's patch fixes the return type of ndo_start_xmit function. Two patches by Shubhrajyoti Datta add support for the CAN FD 2.0 controllers. Flavio Suligoi's patch for the sja1000 driver add support for the ASEM CAN raw hardware. Wolfram Sang's and Kuninori Morimoto's patches switch the rcar driver to use SPDX license identifiers. The remaining 111 patches improve the flexcan driver. Pankaj Bansal's patch enables the driver in Kconfig on all architectures with IOMEM support. The next four patches by me fix indention, add missing parentheses and comments. Aisheng Dong's patches add self wake support and document it in the DT bindings. The remaining patches by Pankaj Bansal first fix the loopback support and prepare the driver for the CAN-FD support needed for the LX2160A SoC. The actual CAN-FD support will be added in a later patch series. ==================== Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Fixes 2018-11-28 This series contains fixes to igb, ixgbe and i40e. Yunjian Wang from Huawei resolves a variable that could potentially be NULL before it is used. Lihong fixes an i40e issue which goes back to 4.17 kernels, where deleting any of the MAC filters was causing the incorrect syncing for the PF. Josh Elsasser caught that there were missing enum values in the link capabilities for x550 devices, which was preventing link for 1000BaseLX SFP modules. Jan fixes the function header comments for XSK methods. ==================== Signed-off-by: -

The response for a SNMP request can consist of multiple parts, which the cmd callback stages into a kernel buffer until all parts have been received. If the callback detects that the staging buffer provides insufficient space, it bails out with error. This processing is buggy for the first part of the response - while it initially checks for a length of 'data_len', it later copies an additional amount of 'offsetof(struct qeth_snmp_cmd, data)' bytes. Fix the calculation of 'data_len' for the first part of the response. This also nicely cleans up the memcpy code. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

-
Ioana Ciocoi Radulescu authored
Instead of freeing the RX buffers, release them back into the pool. We wait for the maximum number of buffers supported by a single release command to accumulate before issuing the command. Also, don't unmap the Rx buffers at the beginning of the Rx routine anymore, since that would require remapping them before release. Instead, just do a DMA sync at first and only unmap if the frame is meant for the stack. Signed-off-by:

Ioana Ciocoi Radulescu authored
We keep one XDP program reference per channel. The only actions supported for now are XDP_DROP and XDP_PASS. Until now we didn't enforce a maximum size for Rx frames based on MTU value. Change that, since for XDP mode we must ensure no scatter-gather frames can be received. Signed-off-by:

The message buffer RAM area is not a contiguous 1KB area but 2 partitions of 512 bytes each. Till now, we used Message buffers with payload size 8 bytes, which translates to 32 MBs per partition and no spare space is left in any partition. However, in upcoming SOC LX2160A the message buffers can have payload size 64 bytes. This results in less than 32 MBs per partition and some empty area is left at the end of each partition.This empty area should not be accessed. Therefore, split the Message Buffer RAM area into two partitions. Signed-off-by:

rx offload depends on number of message buffers, which in turn depends on messgae buffer size. with the upcoming LX2160A SOC the message buffer size can be configured to 72 bytes if it were to be used in CAN FD mode. The current mode in which the flexcan is being operated is known at the time of flexcan_open() but not at the time of flexcan_probe(). Therefore, move the rx_offload_add() from flexcan_probe() to flexcan_open(). correspondingly, move rx_offload_delete() from flexcan_remove() to flexcan_close(). Signed-off-by:
