Subject: [PATCH v3 net-next 1/7] net: page_pool: add helper function to retrieve dma addresses
Date: Wed, 5 Jun 2019 16:20:03 +0300 [thread overview]
Message-ID: <20190605132009.10734-2-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <20190605132009.10734-1-ivan.khoronzhuk@linaro.org>
From: Ilias Apalodimas <ilias.apalodimas@linaro.org>
On a previous patch dma addr was stored in 'struct page'.
Use that to retrieve DMA addresses used by network drivers
