origin code:
if(wrqu->encoding.length!=0){

for(i=0 ; i<4 ; i++){
hwkey[i] |= key[4*i+0]&mask;
if(i==1&&(4*i+1)==wrqu->encoding.length) mask=0x00;
if(i==3&&(4*i+1)==wrqu->encoding.length) mask=0x00;
hwkey[i] |= (key[4*i+1]&mask)<<8;
hwkey[i] |= (key[4*i+2]&mask)<<16;
hwkey[i] |= (key[4*i+3]&mask)<<24;
}
....
I think "i == 1 && (4*i+1)" statement is same as 5, so it seems to be
"if (wrqu->encoding.length == 5)". Once mask value is set to zero, it
doesn't need to set anymore. (I don't know what the "5" means :-) )
It is just my opinion.
