Before getting in the details of the 1000+ lines of text, lets please have some basic protocol set as it is unlikely going to conclude with one patch.

1. Please version your patches as "PATCH v0" -> PATCH v1" etc.
2. add change log of major items changed/removed/added, so reviewer can focus on those at priority while ignoring existing things from vN to vN+1.

3. Split giant 1000+ lines of text to smaller incremental patches.

An example for this would be,
a. overview of fabrics 
b. Theory of operation
c. descriptor structures
d. device/transport Notifications
e. Queue connect/disconnect commands
f. control path commands (get/set features etc)
g. data transfer commands and responses
h. conformance sections
