SMC: Add support for SMCD(v2)
Add SMCD(v2) clc proposal/accept/confirm and decline support. Proposal and decline parsing routines are used by SMC-R and SMC-D(v2).
Enhance the existing SMC-R protocol dissector in such a generic way that it supports both SMC-R and SMC-D(v2) protocols. These two protocols are similar to each other. SMC-D has a version 1 and version 2.
Details of the protocol SMCD(v2) can be seen here: https://www.ibm.com/support/pages/node/6326337
SMCD(v2) Protocol became part of the linux kernel: https://lwn.net/Articles/832855/
