From 97bd4ef9a0fecfc660231d9547f94a8df616e8df Mon Sep 17 00:00:00 2001 From: Beilei Xing Date: Mon, 8 Jan 2018 11:09:13 +0800 Subject: [PATCH] net/i40e: support input set configuration This patch supports getting/setting input set info for RSS, FDIR, and FDIR flexible payload. It also adds some helper functions for input set configuration.
