From: Rasmus Villemoes Date: Wed, 16 Nov 2022 10:52:02 +0000 (+0100) Subject: net: dsa: refactor name assignment for user ports X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0171a1d22bb99174671484f409f66f5b96c073b4;p=linux.git net: dsa: refactor name assignment for user ports The following two patches each have a (small) chance of causing regressions for userspace and will in that case of course need to be reverted. In order to prepare for that and make those two patches independent and individually revertable, refactor the code which sets the names for user ports by moving the "fall back to eth%d if no label is given in device tree" to dsa_slave_create(). No functional change (at least none intended).
