From 4cd9d227ab838b3590c4b27e3707b8c3ef14d7e9 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Wed, 25 Jun 2025 16:43:15 +0200 Subject: [PATCH] net: airoha: Get rid of dma_sync_single_for_device() in airoha_qdma_fill_rx_queue() Since the page_pool for airoha_eth driver is created with PP_FLAG_DMA_SYNC_DEV flag, we do not need to sync_for_device each page received from the pool since it is already done by the page_pool codebase.
