    Description

      Description of problem:

      Related to https://bugzilla.redhat.com/show_bug.cgi?id=2060476

      A backport of ovs-configuration introduced the use of ip -j addr show to output JSON for easier parsing.  Unfortunately the iproute2 version on RHEL 7.9 is too old to support the -j JSON option

      configure-ovs.sh[1516]: + extra_if_brex_args=
configure-ovs.sh[1516]: ++ ip -j a show dev bond0
configure-ovs.sh[1516]: ++ jq '.[0].addr_info | map(. | select(.family == "inet")) | length'
configure-ovs.sh[1516]: Option "-j" is unknown, try "ip -help".
configure-ovs.sh[1516]: + num_ipv4_addrs=
configure-ovs.sh[1516]: + '[' '' -gt 0 ']'
configure-ovs.sh[1516]: /usr/local/bin/configure-ovs.sh: line 290: [: : integer expression expected

      Version-Release number of selected component (if applicable):

      4.8.0-0.nightly-2022-11-02-105425

      How reproducible:

      Always

      Steps to Reproduce:

      1. Deploy OVN cluster
2. Add RHEL 7.9 DHCP workers
3. oc adm node-logs $node -u ovs-configuration

      Actual results:

      As above

      Option "-j" is unknown, try "ip -help".

      Expected results:

      ovs-configuration succeeds

      + extra_if_brex_args=
++ ip a show dev bond0
++ grep -E '^[[:blank:]]*inet\b'
++ wc -l
+ num_ipv4_addrs=1
+ '[' 1 -gt 0 ']'
+ extra_if_brex_args+='ipv4.may-fail no '
++ ip a show dev bond0
++ grep -E '^[[:blank:]]*inet6\b'
++ grep -v '\bscope link\b'
++ wc -l
+ num_ip6_addrs=1
+ '[' 1 -gt 0 ']'
+ extra_if_brex_args+='ipv6.may-fail no '
