	  Number of TX frames which can be buffered in the driver.

	  Number of TX DMA descriptors. Each descriptor stores the memory address of a
	  data fragment and its size.

	int "Number of RX DMA descriptors"
	default 12
	help
	  Number of RX DMA descriptors. Each descriptor stores the memory address of a
	  data fragment and its size. The data fragments are pre-allocated from the rx
	  network buffers (CONFIG_NET_BUF_RX_COUNT). When a frame is received, it is
	  forwarded to the network stack without copying the data. The buffers
	  in the descriptors are replaced by new pre-allocated buffers.

	bool "Hardware filter VLAN frames"

	depends on NET_VLAN
	help
	  Hardware filter VLAN frames in hardware. Only ethernet frames with
	  a tag configured using vlan_setup() call will be received.
	  The filtering can only be done on one vlan tag. If vlan_setup() is
	  called multiple times, the filtering will be done on the latest
	  tag.

config PTP_CLOCK_XMC4XXX
	bool "XMC4XXX PTP clock driver support"
	default y
	depends on PTP_CLOCK
	help
	  Enable XMC4XXX PTP Clock support.
