Hello, I am trying to modify cw_ in the mac-802_11.h file. Normally, it is cw_=(cw_<<1)+1. However, whenever I do something like cw_=cw_*5, for example, there is a Floating Exception (core dumped) error. Does anyone know why cw_ may be needed to be modified in a bitshifting manner or how to modify it more simply? Thank you in advance for the help. -Arnab
