100M port timer
Default =5
Multicast timer
Unicast timer
Unit time = 80 nsec.(for 64Bytes Frame.)
Default =5
Default =5
Note that the Frame Engine determines the tic value dependent upon the frame. If short frame, it takes above
value. For long frame (> 64 frame), it will double the above value as the reference.
