config NET_BFIN
	bool "Blackfin devices"
	depends on BF516 || BF518 || BF526 || BF527 || BF536 || BF537
	---help---
	  If you have a network (Ethernet) card belonging to this class, say Y.
	  Make sure you know the name of your card. Read the Ethernet-HOWTO,
	  available from <http://www.tldp.org/docs.html#howto>.

	  If unsure, 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 remaining Blackfin card questions. If you say Y, you will be
	  asked for your specific card in the following questions.

if NET_BFIN

config BFIN_MAC
	tristate "Blackfin on-chip MAC support"
	depends on (BF516 || BF518 || BF526 || BF527 || BF536 || BF537)
	select CRC32
	select NET_CORE
	select MII
	select PHYLIB
	select BFIN_MAC_USE_L1 if DMA_UNCACHED_NONE
	---help---
	  This is the driver for Blackfin on-chip mac device. Say Y if you want
	  it compiled into the kernel. This driver is also available as a
	  module ( = code which can be inserted in and removed from the running
	  kernel whenever you want). The module will be called bfin_mac.

config BFIN_MAC_USE_L1
	bool "Use L1 memory for rx/tx packets"
	depends on BFIN_MAC && (BF527 || BF537)
	default y
	---help---
	  To get maximum network performance, you should use L1 memory as rx/tx
	  buffers. Say N here if you want to reserve L1 memory for other uses.

config BFIN_TX_DESC_NUM
	int "Number of transmit buffer packets"
	depends on BFIN_MAC
	range 6 10 if BFIN_MAC_USE_L1
	range 10 100
	default "10"
	---help---
	  Set the number of buffer packets used in driver.

config BFIN_RX_DESC_NUM
	int "Number of receive buffer packets"
	depends on BFIN_MAC
	range 20 100 if BFIN_MAC_USE_L1
	range 20 800
	default "20"
	---help---
	  Set the number of buffer packets used in driver.

config BFIN_MAC_USE_HWSTAMP
	bool "Use IEEE 1588 hwstamp"
	depends on BFIN_MAC && BF518 && PTP_1588_CLOCK && !(BFIN_MAC=y && PTP_1588_CLOCK=m)
	default y
	---help---
	  To support the IEEE 1588 Precision Time Protocol (PTP), select y here
