Is it possible that modern wireless card only supports WPA and not WEP or this is a bug in the driver?

Exactly, I got errors while trying to use WEP with FreeBSD-based 
wireless access point. And I looked in four eyes at all options and 
capabilities.
And I first thought that WEP support is a problem. Basically AP with WEP 
encryption doesn't work with this card.
Now I wonder if this software-based WEP support can be responsible for 
this failure.

Ok I will correct myself: this is very confusing to people who look and 
notice. Though there are not too many obviously.
But caps are mentioned in the handbook. And it particularly says there:

   ifconfig /ath0/ list caps
   <skip>
   This output displays the card capabilities <skip>
   Various supported ciphers are also mentioned: WEP, TKIP, WPA2, etc.,
   these informations are important to know what security protocols
   could be set on the Access Point.


So from this one can conclude that WEP isn't supported. I guess it's 
good to mention
here that WEP is always supported no matter what WEP flag says.
