/*! \file "cmd_buf.c"
\brief This file contain the management function of internal Command Buffer
for CMD_INFO_T.
We'll convert the OID into Command Packet and then send to FW. Thus we need
to copy the OID information to Command Buffer for following reasons.
1. The data structure of OID information may not equal to the data structure of
Command, we cannot use the OID buffer directly.
2. If the Command was not generated by driver we also need a place to store the
information.
3. Because the CMD is NOT FIFO when doing memory allocation (CMD will be generated
from OID or interrupt handler), thus we'll use the Block style of Memory Allocation
here.
