Subject: [PATCH 04/10] net: hisilicon: HI13X1_GMAX skip write LOCAL_PAGE_REG
Date:   Fri, 5 Jul 2019 14:11:13 +0800
Message-ID: <1562307073-103681-1-git-send-email-xiaojiangfeng@huawei.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

HI13X1_GMAC changed the offsets and bitmaps for
GE_TX_LOCAL_PAGE_REG registers in the same peripheral
device on different models of the hip04_eth. With the
default configuration, HI13X1_GMAC can also work without
any writes to the GE_TX_LOCAL_PAGE_REG register.
