Subject: [PATCH 02/10] staging: lustre: lnet: use struct lnet_ioctl_config_data for NI query
From: Amir Shehata <amir.shehata@...el.com>
The functions used to query the NI state passes around the
individual fields of struct lnet_ioctl_config_data. To simplify
the code lets just pass struct lnet_ioctl_config directly.
