44 driver supports PCI/PCIe/CardBus wireless adapters based on the Ralink RT2500,
45 RT2501, RT2600, RT2700, RT2800, RT3090 and RT3900E chipsets.
47 The RT2500 chipset is the first generation of 802.11b/g adapters from Ralink.
48 It consists of two integrated chips, an RT2560 MAC/BBP and an RT2525 radio
51 The RT2501 chipset is the second generation of 802.11a/b/g adapters from
53 It consists of two integrated chips, an RT2561 MAC/BBP and an RT2527 radio
55 This chipset provides support for the IEEE 802.11e standard with multiple
56 hardware transmission queues and allows scatter/gather for efficient DMA
59 The RT2600 chipset consists of two integrated chips, an RT2661 MAC/BBP and an
60 RT2529 radio transceiver.
61 This chipset uses the MIMO (multiple-input multiple-output) technology with
62 multiple radio transceivers to extend the operating range of the adapter and
63 to achieve higher throughput.
64 However, the RT2600 chipset does not support any of the 802.11n features.
66 The RT2700 chipset is a low-cost version of the RT2800 chipset.
67 It supports a single transmit path and two receiver paths (1T2R).
68 It consists of two integrated chips, an RT2760 or RT2790 (PCIe) MAC/BBP and
69 an RT2720 (2.4GHz) or RT2750 (2.4GHz/5GHz) radio transceiver.
71 The RT2800 chipset is the first generation of 802.11n adapters from Ralink.
72 It consists of two integrated chips, an RT2860 or RT2890 (PCIe) MAC/BBP and
73 an RT2820 (2.4GHz) or RT2850 (2.4GHz/5GHz) radio transceiver.
74 The RT2800 chipset supports two transmit paths and up to three receiver
76 It can achieve speeds up to 144Mbps (20MHz bandwidth) and 300Mbps (40MHz
79 The RT3090 chipset is the first generation of single-chip 802.11n adapters
95 virtual interface may be configured at a time.
98 virtual interfaces may be configured together with a
103 interfaces may be operated together with a
105 interface to construct a wireless repeater device.
107 The RT3900E chipset is a single-chip 802.11n adapters from Ralink.
108 The MAC/Baseband Processor can be an RT5390 or RT5392.
109 The RT5390 chip operates in the 2GHz spectrum and supports 1 transmit path
110 and 1 receiver path (1T1R).
111 The RT5392 chip operates in the 2GHz spectrum and supports up to 2 transmit
112 paths and 2 receiver paths (2T2R).
114 The transmit speed is user-selectable or can be adapted automatically by the
115 driver depending on the number of hardware transmission retries.

281 driver was written by
282 .An Damien Bergamini Aq damien@openbsd.org .
286 driver does not make use of the hardware cryptographic engine.
290 driver does not support any of the 802.11n capabilities offered by
291 the RT2700 and RT2800 chipsets.
292 Additional work is required in before those features can be supported.
294 Host AP mode doesn't support power saving.
295 Clients attempting to use power saving mode may experience significant
296 packet loss (disabling power saving on the client will fix this).
300 adapters seem to strictly require a system supporting PCI 2.2 or greater and
301 will likely not work in systems based on older revisions of the PCI
