[PATCH V2 0/3] basic device IOTLB support for vhost_net

This patch tries to implement an device IOTLB for vhost. This could be used with for co-operation with userspace IOMMU implementation (qemu) for a secure DMA environment (DMAR) in guest. The idea is simple. When vhost meets an IOTLB miss, it will request the assistance of userspace to do the

[PATCH net-next V2 02/10] net/mlx5e: Add TXQ set max rate support

From: Yevgeny Petrilin Implement set_maxrate ndo. Use the rate index from the hardware table to attach to channel SQ/TXQ. In case of failure to configure new rate, the queue remains with unlimited rate. We save the configuration on priv structure and apply it each time

[PATCH net-next V2 09/10] net/mlx5e: Use new ethtool get/set link ksettings API

From: Gal Pressman Use new get/set link ksettings and remove get/set settings legacy callbacks. This allows us to use bitmasks longer than 32 bit for supported and advertised link modes and use modes that were previously not supported. Signed-off-by: Gal Pressman

[PATCH net-next V2 01/10] net/mlx5: Rate limit tables support

From: Yevgeny Petrilin Configuring and managing HW rate limit tables. The HW holds a table of rate limits, each rate is associated with an index in that table. Later a Send Queue uses this index to set the rate limit. Multiple Send Queues can have the same rate limit,

From: Tariq Toukan In this mode the moderation timer will restart upon new completion (CQE) generation rather than upon interrupt generation. The outcome is that for bursty traffic the period timer will never expire and thus only the moderation frames counter will dictate
