Subject: [PATCH V2 08/13] pm80xx : IOCTL functionality to get phy error.
Date: Fri, 17 Jan 2020 12:49:18 +0530	[thread overview]
Message-ID: <20200117071923.7445-9-deepak.ukey@microchip.com> (raw)
In-Reply-To: <20200117071923.7445-1-deepak.ukey@microchip.com>

From: Viswas G <Viswas.G@microchip.com>

Added the IOCTL functionality for phy error so that management utility
can get the information like Invalid dword count, Disparity error count,
Loss of sync dword count, phy reset count from driver using get phy
profile command.
