ethernet: constify references to netdev->dev_addr in drivers

2024-01-05T14:13:37+00:00

[ Upstream commit 766607570becbd26cab6d66a544dd8d0d964df5a ]

This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.

No functional changes.

qed: Add NVMeTCP Offload IO Level FW Initializations

2021-06-03T21:04:17+00:00

This patch introduces the NVMeTCP FW initializations which is used
to initialize the IO level configuration into a per IO HW
resource ("task") as part of the IO path flow.

This includes:
- Write IO FW initialization
- Read IO FW initialization.
- IC-Req and IC-Resp FW exchange.
- FW Cleanup flow (Flush IO).
