2 tristate "STMicroelectronics 10/100/1000 Ethernet driver"
8 This is the driver for the Ethernet IPs are built around a
9 Synopsys IP Core and only tested on the STMicroelectronics
14 config STMMAC_DEBUG_FS
15 bool "Enable monitoring via sysFS "
17 depends on STMMAC_ETH && DEBUG_FS
19 The stmmac entry in /sys reports DMA TX/RX rings
20 or (if supported) the HW cap register.
23 bool "STMMAC DMA arbitration scheme"
26 Selecting this option, rx has priority over Tx (only for Giga
28 By default, the DMA arbitration scheme is based on Round-robin
29 (rx:tx priority is 1:1).
31 config STMMAC_DUAL_MAC
32 bool "STMMAC: dual mac support (EXPERIMENTAL)"
34 depends on EXPERIMENTAL && STMMAC_ETH && !STMMAC_TIMER
36 Some ST SoCs (for example the stx7141 and stx7200c2) have two
37 Ethernet Controllers. This option turns on the second Ethernet
38 device on this kind of platforms.
41 bool "STMMAC Timer optimisation"
43 depends on RTC_HCTOSYS_DEVICE
45 Use an external timer for mitigating the number of network
46 interrupts. Currently, for SH architectures, it is possible
47 to use the TMU channel 2 and the SH-RTC device.
50 prompt "Select Timer device"
51 depends on STMMAC_TIMER
53 config STMMAC_TMU_TIMER
58 config STMMAC_RTC_TIMER
59 bool "Real time clock"
