Zak Kemble says:

====================
net: bcmgenet: add support for GRO software interrupt coalescing

Enable support for software IRQ coalescing and GRO aggregation
and apply conservative defaults which can help improve system
and network performance by reducing the number of hardware
interrupts and improving GRO aggregation ratio.
