net/mlx5e: Rx, Fix checksum calculation for new hardware

2019-07-28T06:28:35Z

[ Upstream commit db849faa9bef993a1379dc510623f750a72fa7ce ] CQE checksum full mode in new HW, provides a full checksum of rx frame. Covering bytes starting from eth protocol up to last byte in the received frame (frame_size - ETH_HLEN), as expected by the stack. Fixing up skb->csum by the driver is not required in such case. This fix is to avoid wrong checksum calculation in drivers which already support the new hardware with the new checksum mode.

net/mlx5: Introduce tunnel entropy control in PCMR register

2019-02-22T21:38:23Z

When using the device packet encapsulation offload, the device calculates an entropy value, representing the inner packet headers. The entropy field is placed inside the outer packet headers. For UDP-type encapsulations, the entropy is placed in the source port field of the UDP header. For GRE-type encapsulations, the entropy is placed in the 8 LSB of the key field in the GRE header. If the device does not recognize the encapsulation type, the entropy is not placed in the packet. Entropy setting can be controlled using PCMR register. if encapsulation offload is not used force_entropy_cap should be set to 0x0. Entropy setting is enabled/disabled using entropy_calc, and could be additionally enabled/disabled for GRE encapsulation by entropy_gre_calc. As a pre-step to automatically control the tunnel entropy, introduce the entropy fields in the PCMR register with no functional change.

net/mlx5: E-Switch, Consider ECPF vport depends on eswitch ownership

2019-02-16T01:25:58Z

ECPF connects to the eswitch through vport 0xfffe. ECPF may or may not be the eswitch manager depending on firmware configuration. 1. If ECPF is eswitch manager: ECPF will take over the eswitch manager responsibility. A rep of the host PF shall be created at the ECPF side for the eswitch manager to control. 2. If ECPF is not eswitch manager: host PF will be the eswitch manager, ECPF acts similar as a VF to the host PF. Host PF will be aware of the ECPF vport presence and control it's rep.

net/mlx5: Add query host params command

2019-02-14T20:14:41Z

The QUERY_HOST_PARAMS command is used by an Embedded CPU Physical Function (ECPF) driver to identify and retrieve information about the PF on the host side. E.g, number of virtual functions and PCI BDF. The number of VFs can be changed on the fly, a function is added to query current number of VFs and will be used in downstream patches.

net/mlx5: Update enable HCA dependency

2019-02-14T20:14:41Z

With the introduction of ECPF, we require that the ECPF driver will aways call enable/disable HCA for that PF in the same way a PF does this for its VFs. The PF is still responsible for calling enable and disable HCA for its VFs. To distinguish between the ECPF executing enable/disable HCA for itself or for the PF, it sets the embedded CPU function bit in the input params struct of these commands. When the bit is cleared and function ID is zero, it refers to the peer PF. Signed-off-by: Bodong Wang Signed-off-by: Eli Cohen Signed-off-by: Saeed Mahameed

net/mlx5: Introduce Mellanox SmartNIC and modify page management logic

2019-02-14T20:14:41Z

Mellanox's SmartNIC combines embedded CPU(e.g, ARM) processing power with advanced network offloads to accelerate a multitude of security, networking and storage applications. With the introduction of the SmartNIC, there is a new PCI function called Embedded CPU Physical Function(ECPF). And it's possible for a PF to get its ICM pages from the ECPF PCI function. Driver shall identify if it is running on such a function by reading a bit in the initialization segment. When firmware asks for pages, it would issue a page request event specifying how many pages it requests and for which function. That driver responds with a manage_pages command providing the requested pages along with an indication for which function it is providing these pages. The encoding before this patch was as follows: function_id == 0: pages are requested for the function receiving the EQE. function_id != 0: pages are requested for VF identified by the function_id value A new one bit field in the EQE identifies that pages are requested for the ECPF. The notion of page_supplier can be introduced here and to support that, manage pages and query pages were modified so firmware can distinguish the following cases: 1. Function provides pages for itself 2. PF provides pages for its VF 3. ECPF provides pages to itself 4. ECPF provides pages for another function This distinction is possible through the introduction of the bit "embedded_cpu_function" in query_pages, manage_pages and page request EQE.
