be2net: refactor be_set_rx_mode() and be_vid_config() for readability
This patch re-factors the filter setting (uc-list, mc-list, promisc, vlan) code in be_set_rx_mode() and be_vid_config() to make it more readable and reduce code duplication. This patch adds a separate field to track the state/mode of filtering, along with moving all the filtering related fields to one place in be be_adapter structure.
