From mboxrd@z Thu Jan 1 00:00:00 1970 From: Marcin Szycik Date: Mon, 16 Aug 2021 16:48:48 +0200 Subject: [Intel-wired-lan] [PATCH net-next] ice: fix ethtool set channel when in switchdev mode Message-ID: <20210816144848.437-1-marcin.szycik@intel.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: intel-wired-lan@osuosl.org List-ID: From: Grzegorz Nitka When running ethtool set channel (-L) command on PF interface, DCB reconfiguration is triggered which in turn involves TC re-configuration and ring to vector mapping. It applies to all VSI instances, regardles of VSI type, so also including switchdev ctrl VSI when device is running in switchdev mode. Skip ring to vector mapping for switchdev ctrl VSI, as it uses non-standard mapping and is already properly configured when PF VSI is rebuilt.
