Subject: [PATCH 11/21] ath10k: add fw-powerup-fail to ethtool stats.
Date: Mon,  9 May 2016 16:11:05 -0700	[thread overview]
Message-ID: <1462835475-11079-12-git-send-email-greearb@candelatech.com> (raw)
In-Reply-To: <1462835475-11079-1-git-send-email-greearb@candelatech.com>

From: Ben Greear <greearb@candelatech.com>

This gives user-space a normal-ish way to detect that
firmware has failed to start and that a reboot is
probably required.
