From 9ee677c2276bfcbcf68042ec2718a504af0c5fd7 Mon Sep 17 00:00:00 2001 From: David Kilroy Date: Tue, 23 Dec 2008 14:03:38 +0000 Subject: wireless: Add channel/frequency conversions to ieee80211.h Added mappings for FHSS, DSSS and OFDM channels - with macros to point HR DSSS and ERP to the DSSS mappings. Currently just static inline functions. Use the new functions in the older fullmac drivers. This eliminates a number of const static buffers and removes a couple of range checks that are now redundant.
