Description

yamux already has a 30s keepalive enabled, for smux it was disabled but can be enabled back removing "config.KeepAliveDisabled = true". it will be useful for cdns which close idle connections (after 10s or 100s). i donated 10$ through crypto.

Research direction

Start by locating the smux configuration containing config.KeepAliveDisabled = true and compare it with yamux's existing 30s keepalive. Determine how the requested keepalive parameters should be exposed for both transports, then verify that idle connections remain alive for CDN-compatible intervals.
