This subsystem is designed for the 2.6 kernel series. It should only
be used with 2.6.8 or higher.
OPTIONAL: WPA Support
If you wish to enable WPA support, you also need to enable the following Crypto
library modules (in addition to those required for WEP above):
Michael MIC (CONFIG_CRYPTO_MICHAEL_MIC)
AES (CONFIG_CRYPTO_AES_586)
ieee80211 uses the WEP encryption and decryption algorithms provided
by the Linux kernel. As such, in order to use WEP you must enable the
Crypto library support (CONFIG_CRYPTO) and the following algorithms:
ARC4 cipher algorithm (CONFIG_CRYPTO_ARC4)
You also need to enable the following from Library routines:
CRC32 (CONFIG_CRC32)
Check for these with:
% for i in CRYPTO_ARC4 CRC32; do \
grep CONFIG_INSTALL \
/lib/modules/2.6.10/build/include/linux/autoconf.h; done
INSTALLING THE BITS
The installation requires the compiled kernel sources or headers
against the matching kernel. These are typically found in:
/lib/modules/\`uname -r\`/build
If that directory does not exist, or is empty, you likely need to
install the kernel source packages for your distribution. Once you have
the kernel sources, you can make and install the ieee80211 subsystem
via:
% tar zxvf ieee80211-${VERSION}
% cd ieee80211-${VERSION}
% make
In order to build drivers dependent on this subsystem, those drivers may
need to find the ieee80211 header files. You can specify a location for
those include files to be installed via the IEEE80211_INC parameter to
make:
% make IEEE80211_INC=/usr/include
which will install the ieee80211.h headers into /usr/include/net
If you do not specify a location, the Makefile will default to
installing into:
/lib/modules/\`uname -r\`/include
