15.3(3)S

Description (partial)

Symptom:
ISSU will break when we do a upgrade/downgrade from xe310 to xe311/xe312/xe313. Only seen when we do

ISSU sub package upgrade from xe310 to xe311/xe312/xe313...../mcp_dev
ISSU sub package downgrade from  xe311/xe312/xe313..../mcp_dev to xe310 

Anyother ISSU upgrade/downgrade cannot see this issue. ISSU super package upgrade/downgrade should not result in this issue. 

Cause: ONLY SUB PACKAGE upgrade/downgrade.

Conditions:
A definite spa type has different TDL enums across xe310 & xe311/xe312/xe313.../mcp_dev which is causing ISSU breakage.

ISSU upgrade/downgrade from all versions of xe310 to xe312 are discussed of them, we list out which are the ones that are affected because of this bug.
