This patch removes IrPORT and the old dongle drivers (all off them
have replacement drivers).

To compile it as a module, choose M here: the module will be called
ks959-sir.
comment "Old SIR device drivers"
config IRPORT_SIR
tristate "IrPORT (IrDA serial driver)"
depends on IRDA && BROKEN_ON_SMP
---help---
Say Y here if you want to build support for the IrPORT IrDA device
driver. To compile it as a module, choose M here: the module will be
called irport. IrPORT can be used instead of IrTTY and sometimes
this can be better. One example is if your IrDA port does not
have echo-canceling, which will work OK with IrPORT since this
driver is working in half-duplex mode only. You don't need to use
irattach with IrPORT, but you just insert it the same way as FIR
drivers (insmod irport io=0x3e8 irq=11). Notice that IrPORT is a
SIR device driver which means that speed is limited to 115200 bps.
If unsure, say Y.
comment "Old Serial dongle support"
config DONGLE_OLD
bool "Old Serial dongle support"
depends on IRPORT_SIR && BROKEN_ON_SMP
help
Say Y here if you have an infrared device that connects to your
computer's serial port. These devices are called dongles. Then say Y
or M to the driver for your particular dongle below.
Note that the answer to this question won't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about serial dongles.
config ESI_DONGLE_OLD
tristate "ESI JetEye PC dongle"
depends on DONGLE_OLD && IRDA
help
Say Y here if you want to build support for the Extended Systems
JetEye PC dongle. To compile it as a module, choose M here. The ESI
dongle attaches to the normal 9-pin serial port connector, and can
currently only be used by IrTTY. To activate support for ESI
dongles you will have to start irattach like this:
"irattach -d esi".
config ACTISYS_DONGLE_OLD
tristate "ACTiSYS IR-220L and IR220L+ dongle"
depends on DONGLE_OLD && IRDA
help
Say Y here if you want to build support for the ACTiSYS IR-220L and
IR220L+ dongles. To compile it as a module, choose M here. The
ACTiSYS dongles attaches to the normal 9-pin serial port connector,
and can currently only be used by IrTTY. To activate support for
ACTiSYS dongles you will have to start irattach like this:
"irattach -d actisys" or "irattach -d actisys+".
config TEKRAM_DONGLE_OLD
tristate "Tekram IrMate 210B dongle"
depends on DONGLE_OLD && IRDA
help
Say Y here if you want to build support for the Tekram IrMate 210B
dongle. To compile it as a module, choose M here. The Tekram dongle
attaches to the normal 9-pin serial port connector, and can
currently only be used by IrTTY. To activate support for Tekram
dongles you will have to start irattach like this:
"irattach -d tekram".
config GIRBIL_DONGLE_OLD
tristate "Greenwich GIrBIL dongle"
depends on DONGLE_OLD && IRDA
help
Say Y here if you want to build support for the Greenwich GIrBIL
dongle. To compile it as a module, choose M here. The Greenwich
dongle attaches to the normal 9-pin serial port connector, and can
currently only be used by IrTTY. To activate support for Greenwich
dongles you will have to insert "irattach -d girbil" in the
/etc/irda/drivers script.
config LITELINK_DONGLE_OLD
tristate "Parallax LiteLink dongle"
depends on DONGLE_OLD && IRDA
help
Say Y here if you want to build support for the Parallax Litelink
dongle. To compile it as a module, choose M here. The Parallax
dongle attaches to the normal 9-pin serial port connector, and can
currently only be used by IrTTY. To activate support for Parallax
dongles you will have to start irattach like this:
"irattach -d litelink".
config MCP2120_DONGLE_OLD
tristate "Microchip MCP2120"
depends on DONGLE_OLD && IRDA
help
Say Y here if you want to build support for the Microchip MCP2120
dongle. To compile it as a module, choose M here. The MCP2120 dongle
attaches to the normal 9-pin serial port connector, and can
currently only be used by IrTTY. To activate support for MCP2120
dongles you will have to insert "irattach -d mcp2120" in the
/etc/irda/drivers script.
You must build this dongle yourself. For more information see:
<http://www.eyetap.org/~tangf/irda_sir_linux.html>
config OLD_BELKIN_DONGLE_OLD
tristate "Old Belkin dongle"
depends on DONGLE_OLD && IRDA
help
Say Y here if you want to build support for the Adaptec Airport 1000
and 2000 dongles. To compile it as a module, choose M here: the module
will be called old_belkin. Some information is contained in the
comments at the top of <file:drivers/net/irda/old_belkin.c>.
config ACT200L_DONGLE_OLD
tristate "ACTiSYS IR-200L dongle (EXPERIMENTAL)"
depends on DONGLE_OLD && EXPERIMENTAL && IRDA
help
Say Y here if you want to build support for the ACTiSYS IR-200L
dongle. To compile it as a module, choose M here. The ACTiSYS
IR-200L dongle attaches to the normal 9-pin serial port connector,
and can currently only be used by IrTTY. To activate support for
ACTiSYS IR-200L dongles you will have to start irattach like this:
"irattach -d act200l".
config MA600_DONGLE_OLD
tristate "Mobile Action MA600 dongle (EXPERIMENTAL)"
depends on DONGLE_OLD && EXPERIMENTAL && IRDA
---help---
Say Y here if you want to build support for the Mobile Action MA600
dongle. To compile it as a module, choose M here. The MA600 dongle
attaches to the normal 9-pin serial port connector, and can
currently only be tested on IrCOMM. To activate support for MA600
dongles you will have to insert "irattach -d ma600" in the
/etc/irda/drivers script. Note: irutils 0.9.15 requires no
modification. irutils 0.9.9 needs modification. For more
information, download the following tar gzip file.
There is a pre-compiled module on
