+//! DHCP proxy (RFC 4578 "PXE Boot Server Discovery").
+//!
+//! Listens on UDP/67 (broadcast) and UDP/4011 (PXE boot server). Never
+//! assigns IPs — only returns boot parameters (siaddr, option 66 TFTP server,
+//! option 67 boot filename, and the mandatory option 60 "PXEClient" echo).
+//!
+//! Key decisions (see architecture memory for rationale):
+//! - Single code path handles both 67 and 4011; distinguished by port.
+//! - We set `SO_REUSEADDR` + `SO_BROADCAST` and enable `IP_PKTINFO` so we can
+//!   (a) learn the destination interface for multi-homed pods and (b) reply
+//!   back through the correct interface. This lets us run behind host-network
+//!   in OpenShift without needing `SO_BINDTODEVICE` (which requires NET_RAW).
+//! - Classification is: option 77 user-class `iPXE` → serve HTTP script URL;
+//!   option 60 starts `HTTPClient` → serve HTTP URL directly (UEFI HTTP boot);
+//!   otherwise → TFTP + arch-specific iPXE binary.
+//! - We MUST echo `option 60 = "PXEClient"` (or `"HTTPClient"`) in replies or
+//!   clients silently drop them.
