Subject: [spp] [PATCH v2 1/6] shared: add dev_attach_by_devargs
Date: Wed, 21 Nov 2018 15:52:14 +0900 [thread overview]
Message-ID: <201811210652.wAL6qKJe011052@imss04.silk.ntt-tx.co.jp> (raw)
In-Reply-To: <201811070507.wA757WWo008866@imss03.silk.ntt-tx.co.jp>
From: Hideyuki Yamashita <yamashita.hideyuki@po.ntt-tx.co.jp>
SPP uses deprecated APIs removed in DPDK v18.11. Using rte_eth_hotplug_add()
is recommended instead of rte_eth_dev_attach()[1]. This patch is to add
dev_attach_by_devargs() to shared directory so that spp_primary, spp_nfv,
spp_vm and spp_vf can refer this new function.
