# Blackfin device configuration
6
bool "Blackfin devices"
7
depends on BF516 || BF518 || BF526 || BF527 || BF536 || BF537
9
If you have a network (Ethernet) card belonging to this class, say Y.
10
Make sure you know the name of your card. Read the Ethernet-HOWTO,
11
available from <http://www.tldp.org/docs.html#howto>.
15
Note that the answer to this question doesn't directly affect the
16
kernel: saying N will just cause the configurator to skip all
17
the remaining Blackfin card questions. If you say Y, you will be
18
asked for your specific card in the following questions.
23
tristate "Blackfin on-chip MAC support"
24
depends on (BF516 || BF518 || BF526 || BF527 || BF536 || BF537)
29
select BFIN_MAC_USE_L1 if DMA_UNCACHED_NONE
31
This is the driver for Blackfin on-chip mac device. Say Y if you want
32
it compiled into the kernel. This driver is also available as a
33
module ( = code which can be inserted in and removed from the running
34
kernel whenever you want). The module will be called bfin_mac.
36
config BFIN_MAC_USE_L1
37
bool "Use L1 memory for rx/tx packets"
38
depends on BFIN_MAC && (BF527 || BF537)
41
To get maximum network performance, you should use L1 memory as rx/tx
42
buffers. Say N here if you want to reserve L1 memory for other uses.
44
config BFIN_TX_DESC_NUM
45
int "Number of transmit buffer packets"
47
range 6 10 if BFIN_MAC_USE_L1
51
Set the number of buffer packets used in driver.
53
config BFIN_RX_DESC_NUM
54
int "Number of receive buffer packets"
56
range 20 100 if BFIN_MAC_USE_L1
60
Set the number of buffer packets used in driver.
62
config BFIN_MAC_USE_HWSTAMP
63
bool "Use IEEE 1588 hwstamp"
64
depends on BFIN_MAC && BF518
67
To support the IEEE 1588 Precision Time Protocol (PTP), select y here
