4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Sudarsana Reddy Kalluru <sudarsana.kalluru@xxxxxxxxxx> [ Upstream commit ae2dcb28c24794a87e424a726a1cf1a61980f52d ] Rx hash/filter table configuration uses rss_conf_obj to configure filters in the hardware. This object is initialized only when the interface is brought up. This patch adds driver changes to configure rss params only when the device is in opened state. In port disabled case, the config will be cached in the driver structure which will be applied in the successive load path. Please consider applying it to 'net' branch.
