Subject: [dpdk-dev] [PATCH v9 3/6] net/axgbe: use common rte bit operation APIs instead
Date: Fri, 24 Apr 2020 11:21:56 +0800 [thread overview]
Message-ID: <20200424032159.992-4-joyce.kong@arm.com> (raw)
In-Reply-To: <20200424032159.992-1-joyce.kong@arm.com>
In-Reply-To: <1571125801-45773-1-git-send-email-joyce.kong@arm.com>
Remove its own bit operation APIs and use the common one,
this can reduce the code duplication largely.
