config IBM_EMAC
	tristate "PowerPC 4xx on-chip Ethernet support"
	depends on 4xx && !PPC_MERGE
	help
	  This driver supports the PowerPC 4xx EMAC family of on-chip
          Ethernet controllers.

config IBM_EMAC_RXB
	int "Number of receive buffers"
	depends on IBM_EMAC
	default "128"

config IBM_EMAC_TXB
	int "Number of transmit buffers"
	depends on IBM_EMAC
	default "64"

config IBM_EMAC_POLL_WEIGHT
	int "MAL NAPI polling weight"
	depends on IBM_EMAC
	default "32"

config IBM_EMAC_RX_COPY_THRESHOLD
	int "RX skb copy threshold (bytes)"
	depends on IBM_EMAC
	default "256"

config IBM_EMAC_RX_SKB_HEADROOM
	int "Additional RX skb headroom (bytes)"
	depends on IBM_EMAC
	default "0"
	help
	  Additional receive skb headroom. Note, that driver
	  will always reserve at least 2 bytes to make IP header
	  aligned, so usually there is no need to add any additional
	  headroom.

	  If unsure, set to 0.

config IBM_EMAC_PHY_RX_CLK_FIX
	bool "PHY Rx clock workaround"
	depends on IBM_EMAC && (405EP || 440GX || 440EP || 440GR)
	help
	  Enable this if EMAC attached to a PHY which doesn't generate
	  RX clock if there is no link, if this is the case, you will
	  see "TX disable timeout" or "RX disable timeout" in the system
	  log.

	  If unsure, say N.

config IBM_EMAC_DEBUG
	bool "Debugging"
	depends on IBM_EMAC
	default n

config IBM_EMAC_RGMII
	bool
	depends on IBM_EMAC && 440GX
	default y

config IBM_EMAC_TAH
	bool
	depends on IBM_EMAC && 440GX
	default y
