tg(7M)tg(7M)NAMEtg - Tigon3 gigabit ethernet driver
DESCRIPTIONtg is the driver for the Tigon3 gigabit ethernet interfaces.
The Tigon3 chip family is Broadcom Corporation's next generation of
gigabit ethernet controllers, succeeding the Tigon2 chip, which was
controlled by the eg(7m) driver.
The tg driver currently supports the following SGI Tigon3 devices:
P/N 9210283 - PCI card with BCM5701 MAC, copper media
P/N 9210284 - PCI card with BCM5701 MAC, fiber media
Note that the tg driver uses a configuration scheme that is very
different from previous ethernet drivers. It is no longer necessary to
rebuild the kernel and reboot when making configuration changes. See
tgconfig(1M) for details.

BUGS
Link negotiation and detection of link change events with fiber cards is
not yet very robust. It may be necessary to connect these cards via a
switch.
