config IBM_NEW_EMAC
tristate "IBM EMAC Ethernet support"
depends on PPC_DCR
select CRC32
help
This driver supports the IBM EMAC family of Ethernet controllers
typically found on 4xx embedded PowerPC chips, but also on the
Axon southbridge for Cell.
config IBM_NEW_EMAC_RXB
int "Number of receive buffers"
depends on IBM_NEW_EMAC
default "128"
config IBM_NEW_EMAC_TXB
int "Number of transmit buffers"
depends on IBM_NEW_EMAC

select VLAN_8021Q
help
When selected the VLAN QOS support will be enabled.
config IBM_NEW_EMAC_RX_SKB_HEADROOM
int "Additional RX skb headroom (bytes)"
depends on IBM_NEW_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_NEW_EMAC_MASK_CEXT
bool "Mask Carrier Extension signals"
depends on IBM_NEW_EMAC && APM82181
default n
help
During normal idle TX, continously send dummy packets to mask
the Carrier Extension signals. This creates a separate BD
specifically for this purpose.
If unsure, set to N.
