- Add`set_send_buffer_size`and`set_recv_buffer_size` methods for dynamic buffer resizing when`alloc`feature is enabled - Fix window calculation in`last_scaled_window` to prevent negative values and return zero when invalid - Clamp`remote_last_seq`in`dispatch` to prevent underflow and ensure valid sequence numbers - Add`resize`method to`RingBuffer` for owned storage, preserving data order and resetting read pointer - Add comprehensive unit tests for new buffer resizing functionality and window handling edge cases Signed-off-by: longjin <longjin@DragonOS.org>
