[PATCH v2 0/3] wifi: mt76: Fix TX performance degradation when IOMMU is enabled

This series adds a TX preallocated buffer mechanism to fix the TX performance degradation observed after enabling IOMMU.

Currently this feature is only enabled on MT8196, where it has been validated.

Changes in v2:
 - Reword cover letter subject to add wifi: mt76: prefix

Eason Lai (3):
  wifi: mt76: Separate skb and ptr pointers in mt76_txwi_cache
  wifi: mt76: mt792x: Add TX page pool support for IOMMU-enabled systems
  wifi: mt76: mt792x: Restrict TX page pool to MT8196  platform
