+dpaa2-evb: Added Edge Virtual Bridge driver
+
+This contains the following patches migrated from linux-v4.0:
+staging: fsl-dpaa2: evb: Added Edge Virtual Bridge driver
+staging: fsl-dpaa2: evb: Added ethtool port counters
+staging: fsl-dpaa2: evb: Include by default in configuration
+staging: fsl-dpaa2: evb: Rebasing onto kernel 4.0
+staging: fsl-dpaa2: evb: Port to MC-0.7 FLibs
+dpaa2-evb: Set carrier state on port open
+dpaa2-evb: Add support for link state update
+dpaa2-evb: Update flib to MC 8.0.1
+staging: fsl-mc: migrated remaining flibs for MC fw 8.0.0 (split)
+
+Inital patches have been signed-off by:
+Alex Marginean <alexandru.marginean@freescale.com>
+J. German Rivera <German.Rivera@freescale.com>
+Bogdan Hamciuc <bogdan.hamciuc@freescale.com>
+Razvan Stefanescu <razvan.stefanescu@freescale.com>
+
+And reviewed by:
+Stuart Yoder <stuart.yoder@freescale.com>
+
+Porting to linux-v4.1 requires changes related to iflink usage and
+ndo_bridge_getlink() parameters list.

+
+dpaa2-evb: Port to linux-v4.1
+
+Update iflink usage.
+Update evb_getlink() parameter list to match ndo_bridge_getlink().
+
+Signed-off-by: Razvan Stefanescu <razvan.stefanescu@freescale.com>
+
+dpaa2-evb: Add VLAN_8021Q dependency
+
+EVB traffic steering methods related to VLAN require VLAN support in kernel.
+
+Signed-off-by: Razvan Stefanescu <razvan.stefanescu@freescale.com>
+
+dpaa2-evb: Update dpdmux binary interface to 5.0
+
+This corresponds to MC release 0.8.0.
+
+Signed-off-by: Razvan Stefanescu <razvan.stefanescu@freescale.com>
+
+dpaa2-evb: Add support to set max frame length.
+
+All the packets bigger than max_frame_length will be dropped.
+
+Signed-off-by: Mihaela Panescu <mihaela.panescu@freescale.com>
+
+dpaa2-evb: resolve compile issues on uprev to 4.5
+
+-irq_number field no longer exists in fsl-mc interrupt
+ struct
+-netdev_master_upper_dev_link() has 2 new parameters, which
+ are set to NULL for now
