2018-08-03net: hns3: Refine the MSIX allocation for PFJian Shen3-4/+9
The offset of msix number for roce is different between different revision id. We should get it from firmware, instead of a fix value. This patch refines the msix allocation, make it compatible.

2018-08-03net: hns3: Fix MSIX allocation issue for VFJian Shen4-16/+85
The msix number for vf is different, depends on the max vf number. Futherly if the vf supports roce, the offset of msix is not fixed. It's incorrect to fix the msix number to 33. This patch fixes it by querying the msix number from firmware, and adjusting it with roce support.

2018-08-01net: hns3: fix return value error while hclge_cmd_csq_clean failedHuazhong Tan1-3/+9
While cleaning the command queue, the value of the HEAD register is not in the range of next_to_clean and next_to_use, meaning that this value is invalid. This also means that there is a hardware error and the hardware will trigger a reset soon. At this time we should return an error code instead of 0, and HCLGE_STATE_CMD_DISABLE needs to be set to prevent sending command again.

The payload of mailbox message is 16 byte and the value of HCLGE_MBX_MAX_ARQ_MSG_SIZE is 8. A message truncated problem will happen when mailbox message is converted to ARQ message. This patch replaces HCLGE_MBX_MAX_ARQ_MSG_SIZE with the size of ARQ message in hclgevf_mbx_handler to fix this problem.
