net: ravb: Enable SW IRQ Coalescing for GbEth
Software IRQ Coalescing is required to improve network stack performance
in the RZ/G2L SoC family and the RZ/G3S SoC, i.e. the SoCs which use the
GbEth IP.
This patch gives the following improvements during testing with iperf3:
* RZ/G2L:
* TCP RX: same bandwidth with -6% CPU load (76% -> 71%)
* UDP RX: same bandwidth with -10% CPU load (99% -> 89%)
* RZ/G2UL:
* UDP RX: +4200% bandwidth (1.23Mbps -> 53Mbps)
* RZ/G3S:
* UDP RX: +425% bandwidth (1.23Mbps -> 6.46Mbps)
The improvement of UDP RX bandwidth for the single core SoCs (RZ/G2UL &
RZ/G3S) is particularly critical.
