- tg - Tigon3 gigabit ethernet driver
-
- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- _t_g 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 _e_g(7m) driver.
-
- The _t_g driver currently supports the following SGI Tigon3 devices:
-
- PPPP////NNNN 9999222211110000222288883333 - PCI card with BCM5701 MAC, copper media
- PPPP////NNNN 9999222211110000222288884444 - PCI card with BCM5701 MAC, fiber media
-
- Note that the _t_g 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
- _t_g_c_o_n_f_i_g(1M) for details.

- 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.
