From f2ecc9710d49d320409700bc72f42632f72b369d Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Thu, 4 May 2023 22:18:12 +0200 Subject: ethernet: T3891: honor auto-negotiation support per NIC Not all drivers/NICs or combination of NIC + transceiver support auto- negotiation. The current auto-negotiation capability is evaluated and taken into account when applying spped/duplex settings. If auto-negotiation is not supported - we skip the setting to avoid errors during configuration. --- python/vyos/ifconfig/ethernet.py | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) (limited to 'python/vyos/ifconfig') diff --git a/python/vyos/ifconfig/ethernet.py b/python/vyos/ifconfig/ethernet.py index 5080144ff..6a49c022a 100644 --- a/python/vyos/ifconfig/ethernet.py +++ b/python/vyos/ifconfig/ethernet.py @@ -1,4 +1,4 @@ -# Copyright 2019-2021 VyOS maintainers and contributors +# Copyright 2019-2023 VyOS maintainers and contributors # # This library is free software; you can redistribute it and/or # modify it under the terms of the GNU Lesser General Public @@ -14,9 +14,10 @@ # License along with this library.
