Subject: [RFCv7 PATCH net-next 03/36] net: replace multiple feature bits with DECLARE_NETDEV_FEATURE_SET
Date: Wed, 10 Aug 2022 11:05:51 +0800 [thread overview]
Message-ID: <20220810030624.34711-4-shenjian15@huawei.com> (raw)
In-Reply-To: <20220810030624.34711-1-shenjian15@huawei.com>
There are many netdev_features bits group used in drivers, replace them
with DECLARE_NETDEV_FEATURE_SET, prepare to remove all the NETIF_F_XXX
macroes.
