The original table treated BK/RTL/LN SDK defaults as identical, but they differ significantly: - BK72XX: MEM_SIZE=32KB, TCP_SND_BUF=10×MSS — wildly oversized - RTL87XX: MEM_SIZE=5KB, TCP_SND_BUF=5×MSS — already conservative - LN882H: MEM_LIBC_MALLOC=1, TCP_SND_BUF=7×MSS — uses system heap Setting MEM_SIZE=16KB on RTL87XX was an 11KB *increase* from its 5KB SDK default, causing BD_RAM overflow on the mqtt test. Fix: only set MEM_SIZE on BK72XX (where the 32KB→12KB reduction is needed). RTL87XX keeps its SDK 5KB default, LN882H doesn't use it. The comparison table is updated with accurate per-SDK columns.
