Add support for transmit side kernel-TLS acceleration. Offload the crypto encryption to HW. Per TLS connection: - Use a separate TIS to maintain the HW context. - Use a separate encryption key. - Maintain static and progress HW contexts by posting the proper WQEs at creation time, or upon resync. - Use a special DUMP opcode to replay the previous frags and sync the HW context. To make sure the SQ is able to serve an xmit request, increase SQ stop room to cover: - static params WQE, - progress params WQE, and - resync DUMP per frag. Currently supporting TLS 1.2, and key size 128bit. Tested over SimX simulator. Signed-off-by:

Similar to the existing mlx5e_post_nop(), but marks a fence in the WQE control segment. Added as a separate new function to not hurt the performance of the common case. To be used in a downstream patch of the series. Signed-off-by:

When polling a CQE of an SKB-less WQE, don't assume it consumed only one WQEBB. Use wi->num_wqebbs directly instead. In the downstream patch, SKB-less WQEs might have more the one WQEBB, thus this change is needed. Signed-off-by:

Change mlx5e_sq_fetch_wqe to be agnostic to the Work Queue Element (WQE) type. Before this patch, it was specific for struct mlx5e_tx_wqe. In order to allow the change, the function now returns the generic void pointer, and gets the WQE size to do the zero memset. Signed-off-by:

When ctrl->tisn field exists, this indicates an operation (HW offload) on the TCP payload. For such WQEs, inline the headers up to L4. This is in preparation for kTLS HW offload support, added in a downstream patch. Signed-off-by:

Always contain all acceleration functions declarations in 'accel' files, independent to the flags setting. For this, introduce new flags CONFIG_FPGA_{IPSEC/TLS} and use stubs where needed. This obsoletes the need for stubs in 'fpga' files. Remove them. Also use the new flags in Makefile, to decide whether to compile TLS-specific or IPSEC-specific objects, or not. Signed-off-by: -

Do not directly call fpga version of IPsec function from main.c. Wrap it by an accel version, and call the wrapper. This will allow deprecating the FPGA IPsec stubs in downstream patch. Signed-off-by:

Quoting Arnd, We have to do a sync_single_for_device /somewhere/ before the buffer is given to the device. On a non-cache-coherent machine with a write-back cache, there may be dirty cache lines that get written back after the device DMA's data into it (e.g. from a previous memset from before the buffer got freed), so you absolutely need to flush any dirty cache lines on it first. Since the coherency is configurable in this device make sure we cover all configurations by explicitly syncing the allocated buffer for the device before refilling it's descriptors Signed-off-by:

For revision 0x20, the broadcast promisc is enabled by firmware, it's unnecessary to enable it when initializing VF. For revision 0x21, it's necessary to enable broadcast promisc mode when initializing or re-initializing VF, otherwise, it will be unable to send and receive promisc packets.

Ido Schimmel says: ==================== mlxsw: Enable/disable PTP shapers Shalom says: In order to get more accurate hardware time stamping in Spectrum-1, the driver needs to apply a shaper on the port for speeds lower than 40Gbps. This shaper is called a PTP shaper and it is applied on hierarchy 0, which is the port hierarchy. This shaper may affect the shaper rates of all hierarchies. This patchset adds the ability to enable or disable the PTP shaper on the port in two scenarios: 1. When the user wants to enable/disable the hardware time stamping 2. When the port is brought up or down (including port speed change) Patch #1 adds the QEEC.ptps field that is used for enabling or disabling the PTP shaper on a port. Patch #2 adds a note about disabling the PTP shaper when calling to mlxsw_sp_port_ets_maxrate_set(). Patch #3 adds the QPSC register that is responsible for configuring the PTP shaper parameters per speed. Patch #4 sets the PTP shaper parameters during the ptp_init(). Patch #5 adds new operation for getting the port's speed. Patch #6 enables/disables the PTP shaper when turning on or off the hardware time stamping. Patch #7 enables/disables the PTP shaper when the port's status has changed (including port speed change). Patch #8 applies the PTP shaper enable/disable logic by filling the PTP shaper parameters array. ==================== Signed-off-by: -

In order to get more accurate hardware time stamping, the driver needs to enable PTP shaper on the port, for speeds lower than 40 Gbps.

Set the PTP shaper parameters during the ptp_init(). For different speeds, there are different parameters. When the port's speed changes and PTP shaper is enabled, the firmware changes the ETS shaper values according to the PTP shaper parameters for this new speed. The PTP shaper parameters array is left empty for now, will be filled in a follow-up patch. Signed-off-by:
