17.02-rc2: i40e and LSC

17.02-rc2: i40e and LSC

[Ivan Nardi]

Hi guys
we are upgrading our application from dpdk 16.11 to 17.02-rc2 and we are
facing a strange behavior with i40e driver and LSC
If we call rte_eth_dev_configure() with port_conf.intr_conf.lsc = 1, the
call always failed with error

Configuring Port 0 (socket 1)
rte_eth_dev_configure: driver net_i40e does not support lsc
Fail to configure port 0

Everything is fine with 16.11 or with port_conf.intr_conf.lsc = 0 (default
value)

Is this the intended (new) behavior or am I missing something obvious here?
Thanks in advance

Ivan
