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/DPAA""
39.Cd "options QORIQ_DPAA"
40.Cd "device dpaa"
41.Cd "device dtsec"
42.Cd "device miibus"
43.Ed
44.Sh DESCRIPTION
45The
46.Nm
47driver provides support for the DPAA-based gigabit Ethernet controller
48integrated in some of the Freescale system-on-chip devices.
49.Pp
50The
51.Nm
52driver supports the following media types:
53.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
54.It autoselect
55Enable autoselection of the media type and options
56.It 10baseT/UTP
57Set 10Mbps operation
58.It 100baseTX
59Set 100Mbps operation
60.It 1000baseT
61Set 1000baseT operation
62.El
63.Pp
64The
65.Nm
66driver supports the following media options:
67.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
68.It full-duplex
69Set full duplex operation
70.El
71.Pp
72The
73.Nm
74driver supports two operating modes:
75.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
76.It Regular
77Normal mode, utilizing the full datapath acceleration, Buffer Manager, and Queue
78Manager.
79.It Independent
80Runs disconnected from the Buffer Manager and Queue Manager.
81.El
82.Sh HARDWARE
83Gigabit Ethernet controllers built into the following Freescale
84system-on-chip devices are known to work with the
85.Nm
86driver:

88.Bl -bullet -compact

90P2041, P3041
91.It
92P5010, P5020

101.Sh BUGS
102The
103.Nm
104driver assumes that there is only one Frame Manager, and that dtsec0 controls
105the MDIO interface.  Though this is the case for the supported devices, other
106SoCs with the DPAA controller may not work correctly.  Particularly, the P5040
107and P4080 SoCs have two frame managers, which breaks this assumption.
108.Sh HISTORY
109The
110.Nm
111device driver first appeared in
112.Fx 11.0 .
