Subject: [RFCv7 PATCH net-next 22/36] net: core: adjust netdev_sync_xxx_features
Date: Wed, 10 Aug 2022 11:06:10 +0800 [thread overview]
Message-ID: <20220810030624.34711-23-shenjian15@huawei.com> (raw)
In-Reply-To: <20220810030624.34711-1-shenjian15@huawei.com>
The functions netdev_sync_upper_features() and
netdev_sync_lower_features() use NETIF_F_XXX as input parameter
directly, change them to use NETIF_F_XXX_BIT, for all macroes
NETIF_F_XXX will be removed later.
