2015-02-25dpaa_eth: adjust advanced drivers to older kernelMadalin Bucur
Support for multiple drivers per kernel module comes in kernel 3.14 so we are forced to generate several modules for the advanced drivers. This patch can be dropped when the code is rebased on a kernel newer than 3.14. The problem is with the MODULE_DEVICE_TABLE macro that only from 3.14 generates different named structured based on the name parameter. The change that introduces that also needs a synchronized change in scripts/mod/file2alias.c. Signed-off-by: Madalin Bucur <madalin.bucur@freescale.com>

2014-03-24dpaa_eth: add print for proxy probeMarian Rotariu
There is no indication that the proxy interface successfully initialized the attached MAC device. In this way, the user does not know if the device tree is misconfigured or the MAC device successfully probed. Other ways to check the MAC initialization exists, like MAC mem mapped registers, but a simple message in the bootlog seems way more user-friendly.

2013-11-14dpaa_eth: macless control over mac deviceMarian Rotariu
This patch adds a new feature to macless DPAA Ethernet Driver. The macless interface is now able to control a mac device through proxy DPAA Ethernet Driver. To do that, it maintains a reference to a proxy interface. The proxy interface offers a simple API to macless interface for start/stop and for adding and removing mac unicast and multicast addresses. Additionally, this patch will generalize some of mac API handlers. In previous implementation, the mac handler and net_device structure belong to the same network interface. With this patch, mac handler and net_device structure could belong to different network interfaces. This is needed for the new macless multicast capability, when the proxy interface that contains the mac device reference should configure multicast addresses on behalf of a macless interface. This feature is optional and can be activated by setting "proxy" attribute in the device tree node of the macless interfaces. Look in feature design document for more details.
