IP178C
Preliminary Data Sheet
IPv4/IPv6 DiffServ
IP178C checks the DiffServ field of a IPv4 frame or Traffic class field [7:2] (TC[7:2]) of a IPv6 frame and
uses them to decide the frame’s priority if MII register 31.30.[13] DIFFSERV_EN is enabled. IP178C
uses DiffServ or TC [7:2] as index to select one of 64 bits defined in the MII register 31.22~25
DSCP[63:0]. If the bit is “1”, the received frame is handled as a high priority frame.
