33 .Nd "Marvell Gigabit Ethernet 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 gigabit Ethernet controller integrated in Marvell
45 system-on-chip devices.
49 driver supports the following media types:
50 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
52 Enable autoselection of the media type and options
58 Set 1000baseT operation
63 driver supports the following media options:
64 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
66 Set full duplex operation
71 driver supports polled operation when the system is configured with
72 DEVICE_POLLING kernel option, see
78 driver supports reception and transmission of extended frames
83 can be controlled by means of the
91 driver supports interrupts coalescing (IC) so that raising a transmit/receive
92 frame interrupt is delayed, if possible, until a threshold-defined period of
94 The following sysctls regulate this behaviour (separately for each path):
95 .Bl -tag -width indent
96 .It Va dev.mge.X.int_coal.rx_time
97 .It Va dev.mge.X.int_coal.tx_time
99 Value of 0 disables IC on the given path, value greater than zero corresponds
100 to a real time period and is expressed in units equivalent to 64 ticks of the
102 Maximum allowed value depends on MGE hardware revision.
103 User provided values larger than supported will be trimmed to the maximum
105 More details are available in the reference manual of the device.
108 Gigabit Ethernet controllers built into the following Marvell systems-on-chip
109 are known to work with the
119 Kirkwood 88F6281 (MGE V2)
121 Discovery MV78100 (MGE V2)
124 There are also Marvell system controllers for PowerPC processors, which
125 include a variation of this gigabit Ethernet module integrated on chip, and
126 they should also work with the
128 driver, but this wasn't tested:
134 MV64460, MV64461, MV64462
148 device driver first appeared in
154 device driver was written by
155 .An Grzegorz Bernacki.
156 It has been extended with advanced features (polling, interrupt coalescing,
157 multicast, h/w checksum calculation etc.) by
