ethernet: constify references to netdev->dev_addr in drivers

2021-10-14T16:22:11Z

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.

ethernet: Remove redundant 'flush_workqueue()' calls

2021-10-10T10:33:15Z

'destroy_workqueue()' already drains the queue before destroying it, so there is no need to flush it explicitly. Remove the redundant 'flush_workqueue()' calls.

Revert "be2net: disable bh with spin_lock in be_process_mcc"

2021-06-25T18:44:16Z
