What they do release is an API library 49 * called the HCF (Hardware Control Functions) which is supposed to 50 * do the device-specific operations of a device driver for you. The 51 * publically available version of the HCF library (the 'HCF Light') is 52 * a) extremely gross, b) lacks certain features, particularly support 53 * for 802.11 frames, and c) is contaminated by the GNU Public License. 54 * 55 * This driver does not use the HCF or HCF Light at all. Instead, it 56 * programs the Hermes controller directly, using information gleaned 57 * from the HCF Light code and corresponding documentation. 58 * 59 * This driver supports the ISA, PCMCIA and PCI versions of the Lucent 60 * WaveLan cards (based on the Hermes chipset), as well as the newer 61 * Prism 2 chipsets with firmware from Intersil and Symbol. 62 */ 63 64 #include <sys/cdefs.h> 65 __FBSDID("$FreeBSD$");
