Subject: [U-Boot] [PATCH 10/10][v4] driver: net: ldpaa: Add debug information
Date: Wed, 4 Nov 2015 12:26:01 +0530 [thread overview]
Message-ID: <1446620162-21725-11-git-send-email-prabhakar@freescale.com> (raw)
In-Reply-To: <1446620162-21725-1-git-send-email-prabhakar@freescale.com>
Add following debug information in the driver
- Get various DPNI counter values
- Get link status of DPNI objects
- Get information of both ends of connection (DPMAC - DPNI)
Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com>
