Description of problem:

When the patch for multiple WEP keys in ifup-wireless was added,
support for specifying "open" vs "restricted" WEP was broken (which
has worked for many years).

WEP can work in two modes, 'open' or 'restricted'. Despite the name,
'open' is more secure. Many APs only allow 'open'. Most Linux wireless
drivers default to 'restricted'. :(

For many years you could specify what type of WEP you wanted by having
your ifcfg-ethX or keys-ethX have the line:

KEY="open your-key-goes-here"
or
KEY="restricted your-key-goes-here"

When support for multiple WEP keys was added (bug: 127340, bug:
127957) the logic was changed in ifup-wireless and broke the
open/restricted handling for "KEY" (but ironically, not for KEY1,KEY2,
KEY3,KEY4).

The fix is very simple, please add for FC3/RHEL4:
