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