Message-Id: <20221213063543.2408987-1-jiawenwu@trustnetic.com> Date: Tue, 13 Dec 2022 14:35:43 +0800 From: Jiawen Wu <jiawenwu@...stnetic.com> To: netdev@...r.kernel.org, mengyuanlou@...-swift.com Cc: Jiawen Wu <jiawenwu@...stnetic.com> Subject: [PATCH net-next] net: wangxun: Adjust code structure From: Mengyuan Lou <mengyuanlou@...-swift.com> Remove useless structs 'txgbe_hw' and 'ngbe_hw' make the codes clear. And move the same codes which sets MAC address between txgbe and ngbe to libwx.
