clause 48 D2.2

[samir@xxxxxxxxxxxxx (samir thosani)]

Hi!

	In Fig. 48-8, PCS synchronization state diagram, there is an o/p
variable "enable_cdet". Isn't is supposed to be enable_cdet<0:3>, same as
lane_sync_status<0:3> ?
	
	Also, what's the actual "physical" purpose of this variable? By 
definition, it enables/disables COMMA detection. But, like lane_sync_status
determines the definition for sync_status, I can't see the same with 
"enable_cdet", and also with "enbale_deskew" other than enable/disable
definition.

	Also, D2.0 was using "cgbad" and "cggood" variables for Synchronization.
Although D2.2 Synchronization is not using them, they are still defined 
under "48.2.5.1.3 Variables". What's there new role for D2.2 ?
