The current ping intervals are too short for running mirroring tests in simulator. This leads to ping sending a follow-up ping before the reply arrives, thus sending more than the requested 10 ICMP requests. This traffic is seen at the counters, and causes spurious failures. Bump interval and timeout numbers 5x in mirroring tests to address the spurious failures. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

# Test for DSCP prioritization and rewrite. Packets ingress $swp1 with a DSCP
|
|
# tag and are prioritized according to the map at $swp1. They egress $swp2 and
|
|
# the DSCP value is updated to match the map at that interface. The updated DSCP
|
|
# tag is verified at $h2.
|
|
#
|
|
# ICMP responses are produced with the same DSCP tag that arrived at $h2. They
|
|
# go through prioritization at $swp2 and DSCP retagging at $swp1. The tag is
|
|
# verified at $h1--it should match the original tag.
