[08/11] net/hns3: fix ring vector related mailbox command format
Checks
Commit Message
From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>
The format of the ring vector related mailbox commands between driver and
firmware is different from those of other mailbox commands in hns3 network
engine.
This patch fixes the error mailbox command format about the vector of the
rings, the related command opcode as below:
HNS3_MBX_MAP_RING_TO_VECTOR
HNS3_MBX_UNMAP_RING_TO_VECTOR
HNS3_MBX_GET_RING_VECTOR_MAP
Fixes: 463e748964f5 ("net/hns3: support mailbox")
