Also mpt2sas driver is completely in maintains mode and there won't be any new features. Whereas mpt3sas is at its initial baseline with a healthy road map ahead and also we are planning to use same mpt3sas driver for next upcoming Avago IT HBA's. So merging mpt2sas driver with mpt3sas driver may break mpt2sas driver functionality in future, also it will be over head of the maintainer to always check for the backward compatibility of merged driver with the mpt2sas driver.
