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 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
select PTP_1588_CLOCK
default y
---help---
To support the IEEE 1588 Precision Time Protocol (PTP), select y here
