[PATCH 0/3] Fix TX performance degradation when IOMMU is enabled

[Eason Lai]

From: Eason Lai <Eason.Lai at mediatek.com>

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.

Eason Lai (3):
  wifi: mt76: Separate skb and page_pool_buf 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
