wifi0 exist but wlan0 no

[Roberto Guida]

Hello everyone!

Why iwconfig tells me

wifi0     IEEE 802.11b  ESSID:"test"
           Mode:Master  Access Point: Not-Associated   Bit Rate:11 Mb/s
           Sensitivity=1/3
           Retry min limit:8   RTS thr:off   Fragment thr:off
           Encryption key:off
           Power Management:off

eth0      IEEE 802.11b  ESSID:"test"
           Mode:Master  Access Point: Not-Associated   Bit Rate:11 Mb/s
           Sensitivity=1/3
           Retry min limit:8   RTS thr:off   Fragment thr:off
           Encryption key:off
           Power Management:off
           Link Quality:0  Signal level:0  Noise level:0
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:0  Invalid misc:0   Missed beacon:0

but no wlan0 interfaces exist? i remember that the hostap driver creates 
both wifi0 and wlan0, and then one have to configure wlan0 and forget 
about wifi0.. but now i don't have wlan0.. i've blacklisted orinoco_pci, 
so now the only module that is loaded at boot is hostap (and 
hostap_pci).. do i miss something? here is the output of dmesg:

[root at PCGUEST9G9 ~]# dmesg | grep hostap
hostap_pci: 0.4.4-kernel (Jouni Malinen <jkmaline at cc.hut.fi>)
hostap_pci: Registered netdevice wifi0

[root at PCGUEST9G9 ~]# dmesg | grep wifi0
hostap_pci: Registered netdevice wifi0
wifi0: Original COR value: 0x20
wifi0: NIC: id=0x8022 v1.0.0
wifi0: PRI: id=0x15 v1.1.1
wifi0: STA: id=0x1f v1.7.4
wifi0: Intersil Prism2.5 PCI: mem=0xe0500000, irq=11
wifi0: registered netdevice wlan0

what this last line means? and what is instead that eth0 that iwconfig 
shows?

thanx a lot
