Introduce new driver for NXP Ethernet controller
ENETC it a gigabit Ethernet controller found on the LS1028A board.
It supports basic VLAN offloads - tag extraction, injection and hardware
filtering. Inband MDIO connectivity is used for link status
monitoring through the miibus interface. Fixed-link mode is also
supported, which allows for operation of internal cpu to switch port.
Since no admin interrupts are present in hardware, link status polling
has to be used.
Due to a hardware bug software reset of the NIC results in a external
abort. Because of that most of the hardware initialization is done
during attach. This also means that in the case of an fatal error full
board reset is required.
The enetc_hw.h header was imporoted from Linux. It is dual licensed.

+.Sh NAME
+.Nm enetc
+.Nd "Freescale ENETC PCIe Gigabit Ethernet driver"
+.Sh SYNOPSIS
+To compile this driver into the kernel the following lines must be present
+in the kernel configuration file:
+.sp
+.Cd "options SOC_NXP_LS"
+.Cd "device pci"
+.Cd "device fdt"
+.Cd "device iflib"
+.Cd "device enetc"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for ENETC Gigabit Ethernet NIC found in LS1028A SoC.
+.Xr iflib 9
+is used to communicate with the rest of kernel.
+Both physical ports, as well as virtual interfaces connected to the internal
+switch are supported.
+.Pp
+The following hardware offloads have been implemented in this version
+of the driver:
+.Bd -literal
+- Receive IP checksum validation.
+- VLAN tag insertion and extraction.
+- VLAN tag based packet filtering.
+.Ed
+.Pp
+For more information about configuring this device refer to
+.Xr ifconfig 8 .
+.Sh SEE ALSO
+.Xr vlan 4 ,
+.Xr ifconfig 8 ,
+.Xr iflib 9
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Fx 14.0 .
