[dpdk-dev] [PATCH 3/3] driver/net/mpipe: fix a mpipe link initialization ordering issue

[Liming Sun]

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().
