Flower is commonly used to match on packets in many bash-based selftests.
A dump of a flower filter including statistics looks something like this:
[
{
"protocol": "all",
"pref": 49152,
"kind": "flower",
"chain": 0
},
{
...
"options": {
...
"actions": [
{
...
"stats": {
"bytes": 0,
"packets": 0,
"drops": 0,
"overlimits": 0,
"requeues": 0,
"backlog": 0,
"qlen": 0
}
}
]
}
}
]
The JQ query in the helper function tc_rule_stats_get() assumes this form
and looks for the second element of the array.
However, a dump of a u32 filter looks like this:
[
{
"protocol": "all",
"pref": 49151,
"kind": "u32",
"chain": 0
},
{
"protocol": "all",
"pref": 49151,
"kind": "u32",
"chain": 0,
"options": {
"fh": "800:",
"ht_divisor": 1
}
},
{
...
"options": {
...
"actions": [
{
...
"stats": {
"bytes": 0,
"packets": 0,
"drops": 0,
"overlimits": 0,
"requeues": 0,
"backlog": 0,
"qlen": 0
}
}
]
}
},
]
There's an extra element which the JQ query ends up choosing.
Instead of hard-coding a particular index, look for the entry on which a
selector .options.actions yields anything.
