0 = disable aging
1 = enable aging
Forward Oversize Frames
0 = Discard oversize frames
Power-up default =0
1 = Forward oversize

Decrements buffer counter. When the software writes "1" to this
bit, the Frame Engine decreases buffer counter by one.
Buffer counter enable
0 = Disable (no head of line
control
1 = enable
Status counter enable
0 = collect status in counter
disable
1 = collect status in
counter enable
0 = Use external PCS
Default=0
1 = Use internal PCS in
the chip
TX LED will be off when the link is
down and this bit is 0
0 = Gate 0ff TX_En when Link
down
Default =0
1 = Not Gate off TX_En
when Link down
IP Multicast privileges enable: IP
multicast traffic has a privilege over
regular multicast traffic.
0= disable
Default=0
1= enable
Boot Strap Determine by the bootstrap value.
