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_ZMII
bool
depends on IBM_EMAC && (NP405H || NP405L || 44x)
default y
config IBM_EMAC_RGMII
bool
depends on IBM_EMAC && 440GX
default y
config IBM_EMAC_TAH
bool
depends on IBM_EMAC && 440GX
default y
