Summary: DPDK 18.11.5: i40e PMD fails to start X710 port when
set mtu.

Version: 18.11
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: Normal

When i use the i40e PMD to set the mtu, as follows:
1. rte_eth_dev_ stop 2. rte_eth_dev_set_mtu 3. rte_eth_dev_start
The 1 and 2 steps are normal, but step 3 fails. Log as follows:
i40e_alloc_rx queue mbufs(): Failed to allocate mbuf for RX i40e alloc_rx queue mbufs(): Failed to allocate mbuf for RX i40e dev rx queue start(): Failed to allocate RX queue mbuf i40e dev switch queues(): Failed to switch rx queues i40e dev start): Failed to enable VsI
i40e dev rx queue start(): Failed to allocate Rx queue mbuf i40e dev switch queues(): Failed to switch rx queues i40e dev start(): Failed to enable VSI
I don't know why?Sometimes it's normal and sometimes it's not.Only X710 nics has the issue.
