2020-01-07ionic: restrict received packets to mtu sizeShannon Nelson
Make sure the NIC drops packets that are larger than the specified MTU. The front end of the NIC will accept packets larger than MTU and will copy all the data it can to fill up the driver's posted buffers - if the buffers are not long enough the packet will then get dropped. With the Rx SG buffers allocagted as full pages, we are currently setting up more space than MTU size available and end up receiving some packets that are larger than MTU, up to the size of buffers posted. To be sure the NIC doesn't waste our time with oversized packets we need to lie a little in the SG descriptor about how long is the last SG element. At dealloc time, we know the allocation was a page, so the deallocation doesn't care about what length we put in the descriptor.

2020-01-07net/mlx5: DR, Create multiple destination action from dr_create_fteAlex Vesker
Until now it was possible to pass a packet to a single destination such as vport or flow table. With the new support if multiple vports or multiple tables are provided as destinations, fs_dr will create a multiple destination table action, this action should replace other destination actions provided to mlx5dr_create_rule. Each vport destination can be provided with a reformat actions which will be done before forwarding the packet to the vport.

2020-01-07net/mlx5: Increase the max number of channels to 128Fan Li
Currently the max number of channels is limited to 64, which is half of the indirection table size to allow some flexibility. But on servers with more than 64 cores, users may want to utilize more queues. This patch increases the advertised max number of channels to 128 by changing the ratio between channels and indirection table slots to 1:1. At the same time, the driver still enable no more than 64 channels at loading. Users can change it by ethtool afterwards.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-01-06 This series contains updates to igc to add basic support for timestamping. Vinicius adds basic support for timestamping and enables ptp4l/phc2sys to work with i225 devices. Initially, adds the ability to read and adjust the PHC clock. Patches 2 & 3 enable and retrieve hardware timestamps. Patch 4 implements the ethtool ioctl that ptp4l uses to check what timestamping methods are supported. Lastly, added support to do timestamping using the "Start of Packet" signal from the PHY, which is now supported in i225 devices. While i225 does support multiple PTP domains, with multiple timestamping registers, we currently only support one PTP domain and use only one of the timestamping registers for implementation purposes. ==================== Signed-off-by: David S.
