Subject: [PATCH v7 02/12] net/nfp: simplify initialization and remove dead code
Date: Fri, 12 Aug 2022 18:22:20 +0800 [thread overview]
Message-ID: <1660299750-10668-3-git-send-email-chaoyong.he@corigine.com> (raw)
In-Reply-To: <1660299750-10668-1-git-send-email-chaoyong.he@corigine.com>
Calling nfp_net_init() is only done for the corenic firmware flavor
and it is guaranteed to always be called from the primary process,
so the explicit check for RTE_PROC_PRIMARY can be dropped.
The calling graph of nfp_net_init() already guaranteed the free of
resources when it fail, so remove the necessary free logics inside it.
While at it remove the unused member is_phyport from struct nfp_net_hw.
