Enable mlx5 based hardware to report packet pacing capabilities from kernel to user space. Packet pacing allows to limit the rate to any number between the maximum and minimum, based on user settings. The capabilities are exposed to user space through query_device by uhw. The following capabilities are reported: 1. The maximum and minimum rate limit in kbps supported by packet pacing. 2. Bitmap showing which QP types are supported by packet pacing operation.

On some environments, such as certain SRIOV VF configurations, RoCE is not supported for mlx5 Ethernet ports. Currently, the driver will not open IB device on that port. This is problematic, since we do want user-space RAW Ethernet (RAW_PACKET QPs) functionality to remain in place. For that end, enhance the relevant driver flows such that we do create a device instance in that case.

Refactor the netdev notifier registration into a small helper function. This is a pre-step towards having mlx5 IB device over an Ethernet port which doesn't support RoCE. Also, renamed the de-registration helper and the new helper as netdev notifier and not roce, to make it clear this is not only used with roce. This patch doesn't change any functionality.

When enabling many VFs, the total amount of DMA mappings increase significantly. This causes DMA allocations to take a lot of time since they are serialized in the kernel. As a result the driver enters into fatal condition due to timeout and the system hangs. To recover from this we disable MR cache for VFs. PFs will still have a full cache and VFs cache can be manipulated as usual after driver load.

The maximum page size in the mkey context is 2GB. Until today, we didn't enforce this requirement in the code, and therefore, if we got a page size larger than 2GB, we have passed zeros in the log_page_shift instead of the actual value and the registration failed. This patch limits the driver to use compound pages of 2GB for mkeys.

Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler).
