Use CPU ability to perform CRC calculations, by replacing direct calls to crc32_le() with crypto_shash_updata(). The overall performance gain measured with ib_send_bw tool is 10% and it was tested on "Intel CPU ES-2660 v2 @ 2.20Ghz" CPU. ib_send_bw -d rxe0 -x 1 -n 9000 -e -s $((1024 * 1024 )) -l 100 --------------------------------------------------------------------------------------------- | | bytes | iterations | BW peak[MB/sec] | BW average[MB/sec] | MsgRate[Mpps] | --------------------------------------------------------------------------------------------- | crc32_le | 1048576 | 9000 | inf | 497.60 | 0.000498 | | CRC offload | 1048576 | 9000 | inf | 546.70 | 0.000547 | --------------------------------------------------------------------------------------------- Fixes: 8700e3e7 ("Soft RoCE driver") Signed-off-by:

IPoIB driver now uses the new set of callback functions. If the hardware provider supports the new ipoib_options implementation, the driver uses the callbacks in its data path flows, otherwise it uses the driver default implementation for all data flows in its code. The default implementation wasn't change and it is exactly as it was before introduction of acceleration support. Signed-off-by:

This patch is preparing the netdev part at the IPoIB driver to be able to use the ipoib_options. It deals with the two flows from the .ndo: ipoib_open and ipoib_stop. The code is rearranged as follows: * All operations which deal with the hardware resources, (for example change QP state, post-receive etc.) are performed in one place. * All operations that are control oriented (like restart multicast task, start the reap_ah etc.) are performed in separate place. The functions that deal with the hardware resources now located at __ipoib_ib_dev_open for the ipoib_open flow and __ipoib_ib_dev_stop for ipoib_stop. Signed-off-by:

This patch prepares init and teardown flows so we can call them through ipoib_options function pointers. It arranges that area of code as the following: * All operations which deal with the resource allocation/deletion are performed in one place. * All operations that are control oriented, meaning that they are not connected to a specific hardware, are performed in a separate place. The operations for allocation of hardware resources are now in the function ipoib_dev_init_default, and the deletion of all the resources are in ipoib_dev_uninit_default The only exception is the creation of the PD object, which is used both for resource allocation (create QP etc.) and for control flows like creating AH. It also does: * Move creation of rx_ring and tx_ring to be in the resources allocation area. * Move the function ipoib_ib_dev_open that does the open device to the control area instead of the dev_init which creates resources.

Add RDMA netdev interface to ib device structure allowing RDMA netdev devices to be allocated by ib clients. The idea is to allow to providers to optimize IPoIB data path. New struct that includes functions and data member is exposed. It exposes set of callback functions for handling data path flows in IPoIB driver. Each provider can support these set of functions in order to optimize its specific data path, and let IPoIB to leverage its data path. There is an assumption, that providers should give the full set of functions and not only part of them, in order to work properly. Signed-off-by:

HFI1 HW specific support for VNIC functionality. Dynamically allocate a set of contexts for VNIC when the first vnic port is instantiated. Allocate VNIC contexts from user contexts pool and return them back to the same pool while freeing up. Set aside enough MSI-X interrupts for VNIC contexts and assign them when the contexts are allocated. On the receive side, use an RSM rule to spread TCP/UDP streams among VNIC contexts. Reviewed-by:

OPA VEMA function interfaces with the Infiniband MAD stack to exchange the management information packets with the Ethernet Manager (EM). It interfaces with the OPA VNIC netdev function to SET/GET the management information. The information exchanged with the EM includes class port details, encapsulation configuration, various counters, unicast and multicast MAC list and the MAC table. It also supports sending traps to the EM. Reviewed-by:

Previously, ib_uverbs_event_file was suffixed by _file as it contained the actual file information. Since it's now only used as base struct for ib_uverbs_async_event_file and ib_uverbs_completion_event_file, we change its name to ib_uverbs_event_queue. This represents its logical role better.
