Issue with Update operation in Flowfilter and Flowlist Keytypes.

I have faced issue in few test case scenarios while running VTN Coordinator FT scripts for Flowfilter and FLowlist Keytypes. In stable/Be code.

Below are the scenario which is in FT script.

VBRFLOWFILTER_UPDATE
1) Create VTN , VBR, VBRIFPORTMAP, Flowlist and FLowlistentry, VBRFLOWFILTER
2) Create Vbrflowfilterentry with action type "DROP"
3) Update Vbrflowfilter entry to "REDIRECT" --> Issue in Update( Due to redirect destination vnode error) returns 500 Internal server error

VTERMIFFLOWFILTER_UPDATE
1) Create VTN , VBR, VTERMIFPORTMAP, Flowlist and FLowlistentry, VTERMIFLOWFILTER
2) Create Vtermifflowfilterentry with action type "DROP"
3) Update Vtermifflowfilter entry to "REDIRECT" --> Issue in Update( due to dl_src macc address attribute issue) returns 500 Internal server error

FlowlistEntry_UPDATE
1) Create VTN , VBR, VBRIFPORTMAP, Flowlist and FLowlistentry, VBRFLOWFILTER
2) Create Vbrflowfilterentry with action type "DROP"
3) Update FLOWLISTENTRY for SrcIp and DstIp with prefix length attributes --> Returns with 400 error code (Due to improper filling of source ip and network attributes in the Update method)
