rt2x00: Optimize IV/EIV handling
IV and EIV belong to eachother and don't require 2 seperate fields. Instead they can logically be merged into a single array with size 2. With this approach we can simplify the code in rt2x00crypto.c by using a single memcpy() when copying the iv/eiv data. Additionally we can move some code out of if-statements because the if-statement would always be true. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
