bindToDaqInterface()

bool fsw::net::bindToDaqInterface	(	int	sock,
		const std::string &	address,
		const char *	who )

bind() an already-created socket to address on an ephemeral port.

A no-op returning true for "0.0.0.0" or "", so callers need no special case for the dev path. Logs and returns false on failure.

resolveDaqBindAddress()

DaqBindResult fsw::net::resolveDaqBindAddress	(	const ::fsw::config::Config &	cfg,
		const char *	who )

Decide which local address board traffic should leave from, and log the decision.

1. [network].bind_ip set to something other than 0.0.0.0 — use it verbatim. If it cannot be bound, return ok=false. An explicit pin that silently degrades to 0.0.0.0 is this bug wearing a config key.
2. Otherwise auto-detect: the local IPv4 interface whose subnet contains the configured board addresses. Exactly one match is the normal case, on the rig and under the sim (whose boards are 127.0.0.x, matched by loopback's /8).
3. More than one match — return ok=false, naming the candidates. Ambiguity is the defect; picking one is how we got here.
4. No match — 0.0.0.0 with a warning. This is a dev laptop or CI, where the board subnet does not exist and hard-failing would break ./dev.sh.

Parameters

who	Service name for log lines, e.g. "Sequencer".
