2016-01-27net: emaclite: Use indirect reg access in sendMichal Simek
The original logic in the driver was exchanging buffers which are used for sending packet and tx_ping and tx_pong buffers were exchanged all the time to ensure that IP has enough time to send the packet out. Based on this "feature" send function was using nextbuffertouse variable to save which buffer should be used. Before this algorithm was called driver checked that there is free buffer available. This checking remains in the driver but driver tries to use tx_ping first if available. If not, tx_pong buffer is used instead. To reach this code the original condition is met that at least one of the buffer should be available. Testing doesn't show any performance drop when this patch is applied.

During the initialization of PHY the gigabit bit capable is set if the controller is a GEM. However, for sama5d2 and sama5d4, the GEM is configured to support only 10/100.
