FALSE-POSITIVE error from Coverity test tool. Please do NOT remove following comment.
False-positive: SDP uses scratch buffer to hold the attribute value.
The actual size of tSDP_DISC_ATVAL does not matter.
If the array size in tSDP_DISC_ATVAL is increase, we would increase the system RAM usage unnecessarily
