( https://gerrit.osmocom.org/c/upf-benchmark/+/39900?usp=email ) Change subject: testsuites: tunend: upf: Fix wrong format of some ip neigh commands ...................................................................... testsuites: tunend: upf: Fix wrong format of some ip neigh commands The ip-neigh+printf commands were taken from an older gtplab-sysmo2017 which was printing stuff as ".1%02u", but in the gtplab-sysmo2025 testsuite where they were put they were used to print ".%02u". As a result, the following IP addresses where printed: 172.16.32.01 .. 172.16.32.07 172.16.32.08 172.16.32.09 172.16.32.10 It turns out that commands such as ip neigh actually read integers between dots as octal if they start with a leading 0. As a result, addresses .01-.07 were working fine, since those octal values match the decimal ones. However, .08 and .08 failed to be set due to not being octal numbers. As a result, when running eupf tunend ul+dl tests, DL traffic encapsulated back aimed at RAN iface was, for some unknown reason, sent over CN iface instead because it couldn't find an ARP resolution for it, creating misbehaviors when running that testcase.
