Subject: [RFCv7 PATCH net-next 02/36] net: replace general features macroes with global netdev_features variables
Date: Wed, 10 Aug 2022 11:05:50 +0800 [thread overview]
Message-ID: <20220810030624.34711-3-shenjian15@huawei.com> (raw)
In-Reply-To: <20220810030624.34711-1-shenjian15@huawei.com>
There are many netdev_features bits group used in kernel. The definition
will be illegal when using feature bit more than 64. Replace these macroes
with global netdev_features variables, initialize them when netdev module
init.
