From 2817e84549775c66235f1621508331b38c8ff906 Mon Sep 17 00:00:00 2001 From: Yulong Pei Date: Fri, 24 Feb 2023 07:35:58 +0000 Subject: Fix: detaches the attached XDP/BPF program before af_xdp test run When call create af_xdp interface api, it will load default xdp program (xsk_def_prog.o) on the NIC interface, the program will be unloaded when call delete af_xdp interface api, but current csit config did not call delete api for af_xdp test cases, that will cause af_xdp test case fails to run on Intel E810 NIC when the interface already have xdp program attached, so this patch is to fix this issue by to detach any attached XDP/BPF program on the interface before af_xdp test case run.
