Then you can use it for the mad size too. That was debated before and I was hoping to leave that for another day. It does make some sense to roll it in here. > > Not in your patch, but why does read_port_table_lengths use a kmalloc > for what should be a stack allocation? Yuk. I don't know. I almost submitted a separate patch for that. I will clean it up when I combine the functions. I also don't like the way the arrays in read_port_table_lengths are handled. This requires a start_port call when comparing bits. It is easier to just make the array 1 based with index 0 valid only for switches. This is part of the reason there is a separate function and array.
