29.Dt DTSEC 4
30.Os
31.Sh NAME
32.Nm dtsec
33.Nd "Freescale Datapath Acceleration Architecture-based Three-Speed Ethernet Controller device driver"
34.Sh SYNOPSIS
35To compile this driver into the kernel, place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "include ""dpaa/config.dpaa""
39.Cd "device dpaa"
40.Cd "device miibus"
41.Ed
42.Sh DESCRIPTION
43The
44.Nm
45driver provides support for the DPAA-based gigabit Ethernet controller
46integrated in some of the Freescale system-on-chip devices.
47.Pp
48The
49.Nm
50driver supports the following media types:
51.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
52.It autoselect
53Enable autoselection of the media type and options
54.It 10baseT/UTP
55Set 10Mbps operation
56.It 100baseTX
57Set 100Mbps operation
58.It 1000baseT
59Set 1000baseT operation
60.El
61.Pp
62The
63.Nm
64driver supports the following media options:
65.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
66.It full-duplex
67Set full duplex operation
68.El
69.Pp
70The
71.Nm
72driver supports two operating modes:
73.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
74.It Regular
75Normal mode, utilizing the full datapath acceleration, Buffer Manager, and Queue
76Manager.
77.It Independent
78Runs disconnected from the Buffer Manager and Queue Manager.
79.El
80.Sh HARDWARE
81Gigabit Ethernet controllers built into the following Freescale
82system-on-chip devices are known to work with the
83.Nm
84driver:
85.Pp
86.Bl -bullet -compact
87.It
88P2041, P3041
89.It
90P5010, P5020

97.Xr ng_ether 4 ,
98.Xr ifconfig 8
99.Sh BUGS
100The
101.Nm
102driver assumes that there is only one Frame Manager, and that dtsec0 controls
103the MDIO interface.  Though this is the case for the supported devices, other
104SoCs with the DPAA controller may not work correctly.  Particularly, the P5040
105and P4080 SoCs have two frame managers, which breaks this assumption.
106.Sh HISTORY
107The
108.Nm
109device driver first appeared in
110.Fx 11.0 .
