---help---
If you have a network (Ethernet) device belonging to this class, say Y.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about Synopsys devices. If you say Y, you will be asked
for your specific device in the following questions.
if NET_VENDOR_SYNOPSYS
config SYNOPSYS_DWC_ETH_QOS
tristate "Sypnopsys DWC Ethernet QOS v4.10a support"

select MII
depends on OF && HAS_DMA
---help---
This driver supports the DWC Ethernet QoS from Synopsys
