mac80211: remove the dependency on crypto_blkcipher
The only thing that using crypto_blkcipher with ecb does over just using arc4 directly is wrapping the encrypt/decrypt function into a for loop, looping over each individual character. To be able to do this, it pulls in around 40 kb worth of unnecessary kernel modules (at least on a MIPS embedded device). Using arc4 directly not only eliminates those dependencies, it also makes the code smaller. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
