+ The stmmac entry in /sys reports DMA TX/RX rings
+ or (if supported) the HW cap register.

+ default n
+ ---help---
+ Selecting this option, rx has priority over Tx (only for Giga

+ By default, the DMA arbitration scheme is based on Round-robin

+ Some ST SoCs (for example the stx7141 and stx7200c2) have two
+ Ethernet Controllers. This option turns on the second Ethernet
+ device on this kind of platforms.

+ Use an external timer for mitigating the number of network

+ to use the TMU channel 2 and the SH-RTC device.
