Bit 10: Bridge Filter Table Reset (BFTR). When the user configures this bit to BFTR = 1, the Bridge Filter
automatically steps through each of the 4096 Bridge Filter Table addresses, aging all Table entries so that the table
is reset (one-time event each time the user writes BFTR = 1).
Bit 9: Automatic Bridge Filter Enable (BFE)
Bits 8-0: Bridge Filter Aging Period (BFAP[1-9]). These bits provide the binary coded value for the Aging Period.
The valid equivalent decimal values for this variable are 1 to 300. Values larger than 300 will not increase the aging
period above 300 seconds. The default is set to 300 sec.
