2 tristate "STMicroelectronics 10/100/1000 Ethernet driver"
9 This is the driver for the Ethernet IPs are built around a
10 Synopsys IP Core and only tested on the STMicroelectronics
15 config STMMAC_PLATFORM
16 tristate "STMMAC platform bus support"
20 This selects the platform specific bus support for
21 the stmmac device driver. This is the driver used
22 on many embedded STM platforms based on ARM and SuperH
24 If you have a controller with this interface, say Y or M here.
29 tristate "STMMAC support on PCI bus (EXPERIMENTAL)"
30 depends on STMMAC_ETH && PCI && EXPERIMENTAL
32 This is to select the Synopsys DWMAC available on PCI devices,
33 if you have a controller with this interface, say Y or M here.
35 This PCI support is tested on XLINX XC2V3000 FF1152AMT0221
36 D1215994A VIRTEX FPGA board.
40 config STMMAC_DEBUG_FS
41 bool "Enable monitoring via sysFS "
43 depends on STMMAC_ETH && DEBUG_FS
45 The stmmac entry in /sys reports DMA TX/RX rings
46 or (if supported) the HW cap register.
49 bool "STMMAC DMA arbitration scheme"
52 Selecting this option, rx has priority over Tx (only for Giga
54 By default, the DMA arbitration scheme is based on Round-robin
55 (rx:tx priority is 1:1).
58 bool "STMMAC Timer optimisation"
60 depends on RTC_HCTOSYS_DEVICE
62 Use an external timer for mitigating the number of network
63 interrupts. Currently, for SH architectures, it is possible
64 to use the TMU channel 2 and the SH-RTC device.
67 prompt "Select Timer device"
68 depends on STMMAC_TIMER
70 config STMMAC_TMU_TIMER
75 config STMMAC_RTC_TIMER
76 bool "Real time clock"
83 prompt "Select the DMA TX/RX descriptor operating modes"
86 This driver supports DMA descriptor to operate both in dual buffer
87 (RING) and linked-list(CHAINED) mode. In RING mode each descriptor
88 points to two data buffer pointers whereas in CHAINED mode they
89 points to only one data buffer pointer.
92 bool "Enable Descriptor Ring Mode"
95 bool "Enable Descriptor Chained Mode"
