From e82700b8662ce5470ebefebc4dc40949f6b14627 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Niklas=20S=C3=B6derlund?= Date: Mon, 4 Mar 2024 12:08:54 +0100 Subject: [PATCH] ravb: Make it clear the information relates to maximum frame size MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The struct member rx_max_buf_size was added before split descriptor support was added. It is unclear if the value describes the full skb frame buffer or the data descriptor buffer which can be combined into a single skb. Rename it to make it clear it referees to the maximum frame size and can cover multiple descriptors.
