From: Joe Carnuccio <joe.carnuccio@xxxxxxxxxx>
This patch does following to improve RDP processing
- Rename field port_id to d_id in ELS and PUREX iocb structs
to match FW spec.
- Remove redundant comments from ELS and PUREX iocb structs.
- Refactor fields in ELS iocb struct for error subcode
common access.
- Properly use error subcode fields in rdp processing routine.
- Add print logs for alloc failure in purex rdp processing routine.
