Symptoms: The interface stops receiving CAN frames when reception of CAN frame and call to the introduced get_berr_counter function coincide. Reproduction: Ip requests, among others, the berr field for the can interfaces. NOTE that it does so even if called as 'ip link show lo', as interface-based filtering is only done after the system calls to receive interface information. Run candump on a MCP-based can interface that has a lot of traffic (via 'cangen -g1' on another can node). On the system with the MCP chip, run while /bin/true; do ip link > /dev/null ; done; Reception of CAN-frames (as shown by candump) will cease within seconds. This issue got introduced by commit 1b59090a47101b4bf379d2c35986ad3f0bcb2aa1 as access to the SPI registers of the MCP251x were not locked. Issue report and patch courtesy David R.

Enable IEEE 1588 precision time protocol (PTP) support.
Springville/i211 with a blank Flash/iNVM use different PCI IDs. Extend the driver to load despite i210/i211 data sheets claiming tools only, not for driver. Only warn rather than fail on NVM validation failures on Apalis T30. Revise Ethernet MAC address assignment: should now handle up to two instances of custom user MACs (2nd one with a 0x100000 offset). This way customer does not have to worry about NVM on a secondary Ethernet on the carrier board and still gets a valid official MAC address from us (e.g. analogous to how we did it on our Protea carrier board). Use the Toradex OUI as default MAC address if no valid one is encountered. Tested on samples of Apalis T30 2GB V1.0B, V1.0C and Apalis T30 1GB V1.0A both with blank NVMs as well as iNVMs programmed with Intel's defaults.
Springville/i211 with a blank Flash/iNVM use a different PCI ID (tools only, not for driver) than properly programmed ones.
Integrate latest igb driver version 5.1.2 (igb-5.1.2.tar.gz from e1000.sf.net).
Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.

Conflicts: drivers/media/video/tegra_v4l2_camera.c reverted to current driver supporting ACM rather than CSI2 drivers/media/video/videobuf2-dma-nvmap.c drivers/video/tegra/host/Makefile
I211 with a blank iNVM uses a different PCI ID. Hack the driver to load despite i211 data sheet claiming tools only, not for driver. Please note that the existing driver hacks concerning NVM validation skipping and Ethernet MAC address assignment equally apply. Tested on initial samples of Apalis T30 1GB V1.0A.
According to Realtek, the firmware provides power optimizations. The driver works without the firmware. Plus, there are scenarios where the firmware is not available, which makes the driver wait at request_firmware call (i.e., 60 sec wait).
