      net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changes · 0a324f31
      由 Moshe Lazer 提交于 
      In the previous QUERY_PAGES command version we used one command to get the
required amount of boot, init and post init pages.  The new version uses the
op_mod field to specify whether the query is for the required amount of boot,
init or post init pages. In addition the output field size for the required
amount of pages increased from 16 to 32 bits.

In MANAGE_PAGES command the input_num_entries and output_num_entries fields
sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10.

In the pages request event the num_pages field also changed to 32 bits.

In the HCA-capabilities-layout the size and location of max_qp_mcg field has
been changed to support 24 bits.

This patch isn't compatible with firmware versions < 5; however, it  turns out that the
first GA firmware we will publish will not support previous versions so this should be OK.

      net/mlx4_core: Respond to operation request by firmware · fe6f700d
      由 Yevgeny Petrilin 提交于 
      This commit adds new firmware command and new firmware event.  The firmware
raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it
needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ
command. At the moment the supported operation is adding/removing multicast
entries which are used by the firmware for handling NCSI traffic in B0
steering mode.

Also, had to swap the order of mlx4_init_mcg_table() and
mlx4_init_eq_table() to make sure that driver will get events only after
resources are initialized to handle it.

      net/mlx4_en: Fix BlueFlame race · 2d4b6466
      由 Eugenia Emantayev 提交于 
      Fix a race between BlueFlame flow and stamping in post send flow.
Example:
	SW: Build WQE 0 on the TX buffer, except the ownership bit
	SW: Set ownership for WQE 0 on the TX buffer
	SW: Ring doorbell for WQE 0
	SW: Build WQE 1 on the TX buffer, except the ownership bit
	SW: Set ownership for WQE 1 on the TX buffer
	HW: Read WQE 0 and then WQE 1, before doorbell was rung/BF was done for WQE 1
	HW: Produce CQEs for WQE 0 and WQE 1
	SW: Process the CQEs, and stamp WQE 0 and WQE 1 accordingly (on the TX buffer)
	SW: Copy WQE 1 from the TX buffer to the BF register - ALREADY STAMPED!
	HW: CQE error with index 0xFFFF  - the BF WQE's control segment is STAMPED,
		so the BF index is 0xFFFF. Error: Invalid Opcode.
As a result QP enters the error state and no traffic can be sent.

Solution:
When stamping - do not stamp last completed wqe.
