[dpdk-dev] [PATCH] app/testpmd: add cmdline to show LACP bonding info

[dpdk-dev] [PATCH] app/testpmd: add cmdline to show LACP bonding info

[Min Hu (Connor)]

From: Chengchang Tang <tangchengchang@huawei.com>

Add a new cmdline to help diagnostic the bonding mode 4 in testpmd.

Show the lacp information about the bonded device and its slaves:
show bonding lacp info <bonded device port_id>

You can remove {} since it's only one sentence.

Same as above

Also, I understand you want to make it more generic. But it looks not straightforward and hard to read. (People who first touch bonding may not understand which state you're referring to)
What about abstracting a function state_to_str(state):
state_to_str(state){
	switch(state)
	case STATE_LACP_ACTIVE: return "active";
	case ...
}
This is just a suggestion. And it only works with one state not several states co-exist. But I'm sure you can do similar things. My point is only showing "STATE_LACP_ACTIVE" will be better.

I'm not familiar with bonding, will it only have one state? If not, your print will look like "ACTTIMEOUTAGG"?

Please follow the format to use fprintf(stderr, "err message") for all err messages print. You can refer to other print in cmdline.c

It has more one state, But it will not look like "ACTTIMEOUTAGG",
because I add space between them.

BTW, I will make state more readable, change these strings
"ACT", "TIMEOUT", "AGG", "SYNC", "COL", "DIST", "DEF", "EXP"
to
		"ACTIVE",
		"TIMEOUT",
		"AGGREGATION",
		"SYNCHRONIZATION",
		"COLLECTING",
		"DISTRIBUTING",
		"DEFAULTED",
		"EXPIRED"
