>Description:

ThinkPad T23 have internal wireless lan using Intersil Prism2.5 chip.
The dmesg says:
	wi0 at pci2 dev 2 function 0: Intersil Prism2.5 Wireless Lan
	wi0: interrupting at irq 11
	wi0: 802.11 address 00:20:e0:89:18:a4
	wi0: using RF:PRISM2.5 MAC:ISL3874A(PCI), Firmware: 1.3 variant 3

The wi without WEP and wi with 40bit-WEP worked fine. But when I
I tried to use wi with 104-bit WEP in the 104bit-WEP environment,
I found that it could not join to the wireless network. 

>How-To-Repeat:
    On the PC that have the Intersil Prism2.5 Wireless Lan, enable
    104-bit WEP and ping to another machine.

>Fix:
    The following patch is workaround. I don't test to use wi
    with 40bit-WEP.
