dkms source for the Broadcom STA Wireless driver
Broadcom STA is a binary-only device driver to support the following IEEE 802.11a/b/g/n wireless network cards: BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43142-, BCM43224-, BCM43225-, BCM43227-, BCM43228-, BCM4331-, BCM4360-, and BCM4352-based hardware. . This package provides the source code for the wl kernel modules and makes use of the DKMS build utility to install them for the running kernel. The alternative package broadcom-sta-source can be used instead in case of build problems. . The wireless-tools package is also required in order to make use of these modules. Kernel source or headers are required to compile these modules.
