From ffb7ed19ac0a9fa9ea79af1d7b42c03a10da98a5 Mon Sep 17 00:00:00 2001 From: Stanislav Fomichev Date: Wed, 5 Mar 2025 08:37:25 -0800 Subject: net: hold netdev instance lock during ioctl operations Convert all ndo_eth_ioctl invocations to dev_eth_ioctl which does the locking. Reflow some of the dev_siocxxx to drop else clause.
