Author: imp Date: Sun May 3 04:01:43 2009 New Revision: 191762 URL: http://svn.freebsd.org/changeset/base/191762 Log: Bring in Andrew Thompson's port of Sepherosa Ziehau's bwi driver for Broadcom BCM43xx chipsets. This driver uses the v3 firmware that needs to be fetched separately. A port will be committed to create the bwi firmware module. The driver matches the following chips: Broadcom BCM4301, BCM4307, BCM4306, BCM4309, BCM4311, BCM4312, BCM4318, BCM4319 The driver works for 802.11b and 802.11g. Limitations: This doesn't support the 802.11a or 802.11n portion of radios. Some BCM4306 and BCM4309 cards don't work with Channel 1, 2 or 3. Documenation for this firmware is reverse engineered from http://bcm.sipsolutions.net/ V4 of the firmware is needed for 11a or 11n support http://bcm-v4.sipsolutions.net/ Firmware needs to be fetched from a third party, port to be committed # I've tested this with a BCM4319 mini-pci and a BCM4318 CardBus card, and # not connected it to the build until the firmware port is committed.
