33 .Nd "Freescale Three-Speed Ethernet Controller device driver"
35 To compile this driver into the kernel, place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
44 driver provides support for the gigabit Ethernet controller integrated in
45 some of the Freescale system-on-chip devices.
49 driver supports the following media types:
51 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
53 Enable autoselection of the media type and options
59 Set 1000baseT operation
64 driver supports the following media options:
66 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
68 Set full duplex operation
73 driver supports polled operation when the system is configured with
74 DEVICE_POLLING kernel option, see
80 driver supports reception and transmission of extended frames
85 can be controlled by means of the
93 driver supports interrupts coalescing (IC) so that raising a transmit/receive
94 frame interrupt is delayed, if possible, until a threshold-defined period of
95 time has elapsed, or a threshold-defined frame counter has been reached
96 (whichever occurs first). The following sysctls regulate this behaviour:
97 .Bl -tag -width indent
98 .It Va dev.tsec.X.int_coal.rx_time
99 .It Va dev.tsec.X.int_coal.rx_count
100 .It Va dev.tsec.X.int_coal.tx_time
101 .It Va dev.tsec.X.int_coal.tx_count
103 Value of 0 for either time or count disables IC on the given path. Time value
104 1-65535 corresponds to a real time period and is expressed in units equivalent
105 to 64 ticks of the TSEC clock. Count 1-255 represents the number of frames
106 (note that value of 1 is equivalent to IC disabled). User provided values
107 larger than supported will be trimmed to the maximum supported. More details
108 are available in the reference manual of the device.
111 Gigabit Ethernet controllers built into the following Freescale
112 system-on-chip devices are known to work with the
120 MPC8533, MPC8541, MPC8555
123 The enhanced version of the controller (eTSEC), integrated in the following
124 devices, is also supported by this driver:
142 device driver first appeared in
148 device driver was written by
149 .An Piotr Kruszynski.
150 It has been extended with polling and interrupt coalescing support by
151 .An Rafal Jaworowski.
152 It has been further enhanced with multicast, h/w checksum calculation and vlan
