Clause 49 /A/ /K/ /R/ on XGMII question
Page 345 line 30-31 says "The codes for /A/ /K/ and /R/ are used on the
XAUI interface to signal idle. They are not present on the XGMII when
no errorrs have occurred, but certain bit errors cause the XGXS to send
them on the XGMII."
What types of errors would this be? and why would we want allow them to
continue through the 10GBase-R, into the optional WIS and onto the link?
Should these be replaced by /E/?
