SRIO Gen2: Auto Upgrade from v3.2 to v3.3 in 2015.1

Description

When I auto upgrade a system based on a srio_gen2 core released in Vivado 2014.3 to the 2015.1 Vivado release, I see the below information in the auto upgrade log.
 
Upgrade Log for IP '<design_name>_srio_gen2_<instance_name>' 
 
       1. Summary ---------- 
           SUCCESS in the upgrade of design_1_srio_gen2_0_0 from xilinx.com:ip:srio_gen2:3.2 to xilinx.com:ip:srio_gen2:3.3 
      
       2. Interface Information ------------------------ 
              Detected external interface differences while upgrading IP 'design_1_srio_gen2_0_0'.  
              -upgrade has removed interface 'RDIREQ'
              -upgrade has removed interface 'RDTREQ'

Solution

The above message can be safely ignored.


The above mentioned interfaces were hidden, but present in the 2014.3 released cores XML.

They have now been removed from the srio_gen2_v3_3 core XML released in 2015.1.
 
These interfaces were never active and were not exposed to the user.

The functionality on these interfaces were always tied to 0.
 
The removal of these interfaces was done to remove warnings which caused confusion about non-driven signals in the core.
