> The kernel provides __dev_uc_sync and __dev_mc_sync in order for drivers
> which need individual notification of add and delete for each filter.
> These functions allow us to vastly simplify our .set_rx_mode handler. We
> need to implement two functions for sync and unsync which add and remove
> filters respectively.
> 
> This change avoids a very complex and inefficient algorithm which resulted in
> an abnormal latency for the .set_rx_mode ndo operation. The resulting code
> after this change is more readable, more efficient, and less code.
> 
> Due to the callback signature used by these functions we also must update
> several other functions to take a const u8 * pointer.
