Subject: [PATCH iw 2/4] iw: link: mention the need for MAC addr arg in link get_sta cmd usage menu
Date: Fri, 10 Sep 2021 19:46:16 +0530	[thread overview]
Message-ID: <20210910141618.1594617-2-gokulkumar792@gmail.com> (raw)
In-Reply-To: <20210910141618.1594617-1-gokulkumar792@gmail.com>

The usage menu shown when running the hidden "link get_sta" command is not
mentioning the need for the MAC address argument. Without this, the cmd is
always failing with the output shown below.

 $ ./iw dev wlan0 link get_sta
 Usage:  ./iw [options] dev <devname> link get_sta
 ...

To avoid this, let the user know about the mandatory "MAC address" argument
like below.

 $ ./iw dev wlan0 link get_sta
 Usage:  ./iw [options] dev <devname> link get_sta <mac-addr>
 ...
