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_DEBUG_FS
16 bool "Enable monitoring via sysFS "
18 depends on STMMAC_ETH && DEBUG_FS
20 The stmmac entry in /sys reports DMA TX/RX rings
21 or (if supported) the HW cap register.
24 bool "STMMAC DMA arbitration scheme"
27 Selecting this option, rx has priority over Tx (only for Giga
29 By default, the DMA arbitration scheme is based on Round-robin
30 (rx:tx priority is 1:1).
32 config STMMAC_DUAL_MAC
33 bool "STMMAC: dual mac support (EXPERIMENTAL)"
35 depends on EXPERIMENTAL && STMMAC_ETH && !STMMAC_TIMER
37 Some ST SoCs (for example the stx7141 and stx7200c2) have two
38 Ethernet Controllers. This option turns on the second Ethernet
39 device on this kind of platforms.
42 bool "STMMAC Timer optimisation"
44 depends on RTC_HCTOSYS_DEVICE
46 Use an external timer for mitigating the number of network
47 interrupts. Currently, for SH architectures, it is possible
48 to use the TMU channel 2 and the SH-RTC device.
51 prompt "Select Timer device"
52 depends on STMMAC_TIMER
54 config STMMAC_TMU_TIMER
59 config STMMAC_RTC_TIMER
60 bool "Real time clock"
67 prompt "Select the DMA TX/RX descriptor operating modes"
70 This driver supports DMA descriptor to operate both in dual buffer
71 (RING) and linked-list(CHAINED) mode. In RING mode each descriptor
72 points to two data buffer pointers whereas in CHAINED mode they
73 points to only one data buffer pointer.
76 bool "Enable Descriptor Ring Mode"
79 bool "Enable Descriptor Chained Mode"
