Description (partial)

Hardware programming is not happening due to space crunch. Looks like we are leaking Station descriptors (SD)

We tried to reproduce the same issue by creating a stack of 3 switches and connected 3 PC's on these switches. Once done, we auto generated the mac-addresses from the IXIA so that the mac-address table of the stack gets full so that we can check if we are going to lose the mac-address of the connected device or not. Unfortunately, the issue was not reproducible in lab.
