From 811912c46b5886f1aa3bb7a51a6ec1270bc947a8 Mon Sep 17 00:00:00 2001 From: Anatoly Burakov Date: Wed, 18 Sep 2024 22:38:32 -0700 Subject: [PATCH] e1000: fix link power down DPDK commit message net/e1000/base: fix link power down Current code is a result of work to reduce duplication between various device models. However, the logic that was replaced did not exactly match the new logic, and as a result the link power down was not working correctly for some NICs, and the link remained up even when the interface is down. Fix it to correctly power down the link under all circumstances that were supported by old logic.
