Subject: [dpdk-dev] [PATCH v2 3/3] driver/net/mpipe: fix a mpipe link initialization ordering issue
Date: Fri, 8 Jan 2016 09:30:38 -0500 [thread overview]
Message-ID: <1452263438-21634-3-git-send-email-lsun@ezchip.com> (raw)
In-Reply-To: <1452263438-21634-1-git-send-email-lsun@ezchip.com>
Mpipe link structure is initialized in function mpipe_link_init().
Currently it's only called from the eth_dev_ops.dev_start, which
caused crashes when link mgmt APIs (like promiscuous_enable)
was called before eth_dev_ops.dev_start(). This submit fixed it
by calling mpipe_link_init() in rte_pmd_mpipe_devinit().
