[06/15] net: octeon: Convert tasklet API to new bottom half workqueue mechanism

Commit Message

Allen June 21, 2024, 5:05 a.m. UTC

Migrate tasklet APIs to the new bottom half workqueue mechanism. It
replaces all occurrences of tasklet usage with the appropriate workqueue
APIs throughout the cavium/octeon driver. This transition ensures
compatibility with the latest design and enhances performance.
