Public bug reported:
I'm using the following hardware with the p54pci driver:
07:00.0 Network controller: Intersil Corporation ISL3890 [Prism GT/Prism
Duette]/ISL3886 [Prism Javelin/Prism Xbow] (rev 01)
The driver works fine in Managed mode, however, I am not able to assign
the NIC a static IP address when it is in ad-hoc mode:
ja...@fledermaus:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
pan0 no wireless extensions.
wmaster0 no wireless extensions.
wlan0 IEEE 802.11bg ESSID:"Fledermaus"
Mode:Ad-Hoc Frequency:2.412 GHz Cell: Not-Associated
Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
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
ja...@fledermaus:~$ sudo ifconfig wlan0 10.0.0.1
SIOCSIFFLAGS: Operation not supported
This seems to directly trigger this message in syslog:
Jun 19 11:43:54 fledermaus kernel: [ 835.508113] p54pci 0000:07:00.0:
firmware: requesting isl3886
And in dmesg:
[ 835.508113] p54pci 0000:07:00.0: firmware: requesting isl3886
