> Hi guys

> 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?
