Hi Linus and Alan,
This is a totally trivial update of the Wireless Extensions
definition. It just adds a few more #define, so no troubles or pain
expected.
The patch attached applies cleanly to *both* 2.4.0-test12 and
2.2.18 (tested), and I would suggest including it in both kernel
series...
Changes :
o Power Management update (max, min & capa)
-> Needed by the Symbol/Intel/3Com 802.11b driver
o Support for read only "encoding" keys
o Support for TxPower parameter
-> Both needed by the Cisco/Aironet 802.11b driver
By the way, don't look in the kernel for the driver mentionned
above, the majority of the Wireless LAN drivers are not in the kernel
(but in the Pcmcia package or elsewhere), and some in the kernel are
not up to date with the version in the Pcmcia package.
Thanks...
Jean
