Togging ALLMULTI does not require controller reset so have Rx

Browse Source 
filtering handle this. Introduce a new function msk_rxfilter that
handles Rx filter configuration and multicast setup as well as
promiscuous mode. This simplifies code a lot.
Promiscuous mode always have preference to any other Rx
filtering so don't disable the mode when ALLMULTI is set.
