4.16-stable review patch. If anyone has any objections, please let me know. ------------------ From: Fuyun Liang <liangfuyun1@xxxxxxxxxx> [ Upstream commit 3bd6d258b1d5f76744567855d1376358a94f127d ] The return type of hns3_get_rss_key_size is u32. But a negative value is returned. This patch fixes it by replacing the negative value with zero.
