Add a test that sends 2 MB of data using randomly sized small packets (129-512 bytes) over a SOCK_STREAM connection. Packets above GOOD_COPY_LEN (128) bypass the in-place coalescing in recv_enqueue(), forcing each one into its own skb. Without receive queue collapsing, the per-skb overhead eventually exceeds buf_alloc and the connection is reset. The test verifies that all data arrives and that content integrity is preserved.
