The testcase failed as below:
$./vlan_bridge_binding.sh
...
+ adf_ip_link_set_up d1
+ local name=d1
+ shift
+ ip_link_is_up d1
+ ip_link_has_flag d1 UP
+ local name=d1
+ shift
+ local flag=UP
+ shift
++ ip -j link show d1
++ jq --arg flag UP 'any(.[].flags.[]; . == $flag)'
jq: error: syntax error, unexpected '[', expecting FORMAT or QQSTRING_START
 (Unix shell quoting issues?) at <top-level>, line 1:
any(.[].flags.[]; . == $flag)
jq: 1 compile error

Remove the extra dot (.) after flags array to fix this.
