From 0ed16e01313e1f8930dc6a52b22159b20269d4e0 Mon Sep 17 00:00:00 2001 From: Steve Yang Date: Mon, 28 Feb 2022 09:48:59 +0000 Subject: [PATCH] net/iavf: fix function pointer in multi-process This patch uses the index value to call the function, instead of the function pointer assignment to save the selection of Receive Flex Descriptor profile ID. Otherwise the secondary process will run with wrong function address from primary process.
