[PATCH 5.2 44/56] selftests/bpf: reduce time to execute test_xdp_vlan.sh

From: Greg Kroah-Hartman
Date: Thu Aug 08 2019 - 15:08:17 EST


From: Jesper Dangaard Brouer <brouer@xxxxxxxxxx>

[ Upstream commit 13978d1e73d2fcfb6addcf3392707ad68fa88ccb ]

Given the increasing number of BPF selftests, it makes sense to
reduce the time to execute these tests. The ping parameters are
adjusted to reduce the time from measures 9 sec to approx 2.8 sec.
