Faizal Rahim says:
MAC Merge support for frame preemption was previously added for igc:
https://lore.kernel.org/netdev/20250418163822.3519810-1-a...
This series builds on that work and adds support for:
- Harmonizing taprio and mqprio queue priority behavior, based on past
discussions and suggestions:
https://lore.kernel.org/all/20250214102206.25dqgut5tbak2r...
- Enabling preemptible queue support for both taprio and mqprio, with
priority harmonization as a prerequisite.
Patch organization:
- Patches 1-3: Preparation work for patches 6 and 7
- Patches 4-5: Queue priority harmonization
- Patches 6-7: Add preemptible queue support
