# Configure wireless network device options. See iwconfig(8) for more info.
# Mageia prefixes the following variables with WIRELESS_ prefix.
# Valid variables:
# MODE: Ad-Hoc, Managed, etc.
# ESSID: Name of the wireless network
# NWID: Name of this machine on the network. Hostname is default
# FREQ: Frequency to operate on. See CHANNEL
# CHANNEL: Numbered frequency to operate on. See FREQ
# SENS: Sensitivity threshold for packet rejection.
# RATE: Transfer rate. Usually one of Auto, 11, 5, 2, or 1.
# RTS: Explicit RTS handshake. Usually not specified (auto)
# FRAG: Fragmentation threshold to split packets. Usually not specified.
# IWCONFIG: Extra parameters to pass directly to IWCONFIG
# IWPRIV: Extra parameters to pass directly to IWPRIV
#
# redhat-only variables:
# KEY: Encryption key for WEP.
# KEY[1-4]: Encryption key for WEP in position [1-4]
# SECURITYMODE: Security mode, e.g: 'open' or 'restricted'
# SPYIPS: List of IP addresses to "spy" on for link performance stats.
#
# mandriva-only variables:
# WIRELESS_NICK: nickname for wireless connection
# WIRELESS_ENC_KEY: Encryption key for WEP.
# WIRELESS_ENC_MODE: Security mode, e.g: 'open' or 'restricted'
# WIRELESS_XSUPPLICANT: Enabling xsupplicant support
# WIRELESS_XSUPPLICANT_FILE: Custom location for xsupplicant.conf file
# Only meant to be called from ifup.
# unify variables common to RH and Mageia-style ifcfg
