config FSL_ENETC
tristate "ENETC PF driver"
depends on PCI && PCI_MSI && (ARCH_LAYERSCAPE || COMPILE_TEST)
help
This driver supports NXP ENETC gigabit ethernet controller PCIe
physical function (PF) devices, managing ENETC Ports at a privileged
level.
If compiled as module (M), the module name is fsl-enetc.
config FSL_ENETC_VF
tristate "ENETC VF driver"
depends on PCI && PCI_MSI && (ARCH_LAYERSCAPE || COMPILE_TEST)
help
This driver supports NXP ENETC gigabit ethernet controller PCIe
virtual function (VF) devices enabled by the ENETC PF driver.
If compiled as module (M), the module name is fsl-enetc-vf.
config FSL_ENETC_PTP_CLOCK
tristate "ENETC PTP clock driver"
depends on PTP_1588_CLOCK_QORIQ && (FSL_ENETC || FSL_ENETC_VF)
default y
help
This driver adds support for using the ENETC 1588 timer
as a PTP clock. This clock is only useful if your PTP
programs are getting hardware time stamps on the PTP Ethernet
packets using the SO_TIMESTAMPING API.
If compiled as module (M), the module name is fsl-enetc-ptp.
config FSL_ENETC_HW_TIMESTAMPING
bool "ENETC hardware timestamping support"
depends on FSL_ENETC || FSL_ENETC_VF
help
Enable hardware timestamping support on the Ethernet packets
using the SO_TIMESTAMPING API. Because the RX BD ring dynamic
allocation has not been supported and it is too expensive to use
extended RX BDs if timestamping is not used, this option enables
extended RX BDs in order to support hardware timestamping.
