Subject: [PATCH-v2 2/2] iw: Print current time in station info dump
Date: Mon, 9 Sep 2019 13:13:57 -0700 [thread overview]
Message-ID: <1568060037-7481-2-git-send-email-greearb@candelatech.com> (raw)
In-Reply-To: <1568060037-7481-1-git-send-email-greearb@candelatech.com>
From: Ben Greear <greearb@candelatech.com>
This lets us more precisely calculate the absolute timestamp
of last-rix (ie, now - idle).
