From ae4e85bde97c9b216736a5087039f3309a628d24 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 13 Sep 2023 16:29:59 +0100 Subject: [netdevice] Allocate private data for each network upper-layer driver Allow network upper-layer drivers (such as LLDP, which attaches to each network device in order to provide a corresponding LLDP settings block) to specify a size for private data, which will be allocated as part of the network device structure (as with the existing private data allocated for the underlying device driver). This will allow network upper-layer drivers to be simplified by omitting memory allocation and freeing code. If the upper-layer driver requires a reference counter (e.g. for interface initialisation), then it may use the network device's existing reference counter, since this is now the reference counter for the containing block of memory.
