What I did
In certain cases, we get neighbor entries with BCAST MAC. This can be safely ignored from programming the hardware

Why I did it
Directed bcast entries are added as part of Interface IP address creation. The neighbor update is redundant.

How I verified it
Configure neighbor entry with BCAST mac.

sudo ip neigh add 10.1.1.255 lladdr ff:ff:ff:ff:ff:ff dev Ethernet124
NOTICE swss#neighsyncd: :- onMsg: Broadcast Mac recieved, ignoring for 10.1.1.255
