The AIRO driver applies a ctr(aes) on a buffer of considerable size (2400 bytes), and instead of invoking the crypto API to handle this in its entirety, it open codes the counter manipulation and invokes the AES block cipher directly. Let's fix this, by switching to the sync skcipher API instead. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

Note that the answer to this question doesn't directly affect the

kernel: saying N will just cause the configurator to skip all the

questions about these cards. If you say Y, you will be asked for

This is the standard Linux driver to support Cisco/Aironet ISA and
|
|
PCI 802.11 wireless cards.
|
|
It supports the new 802.11b cards from Cisco (Cisco 34X, Cisco 35X
|
|
- with or without encryption) as well as card before the Cisco
|
|
acquisition (Aironet 4500, Aironet 4800, Aironet 4800B).
|
|
|
|
This driver support both the standard Linux Wireless Extensions
|
|
and Cisco proprietary API, so both the Linux Wireless Tools and the
|
|
Cisco Linux utilities can be used to configure the card.
|
|
|
|
The driver can be compiled as a module and will be named "airo".

This is the standard Linux driver to support Cisco/Aironet PCMCIA
|
|
802.11 wireless cards. This driver is the same as the Aironet
|
|
driver part of the Linux Pcmcia package.
|
|
It supports the new 802.11b cards from Cisco (Cisco 34X, Cisco 35X
|
|
- with or without encryption) as well as card before the Cisco
|
|
acquisition (Aironet 4500, Aironet 4800, Aironet 4800B). It also
|
|
supports OEM of Cisco such as the DELL TrueMobile 4800 and Xircom
|
|
802.11b cards.
|
|
|
|
This driver support both the standard Linux Wireless Extensions
|

and Cisco proprietary API, so both the Linux Wireless Tools and the
