extern int ic_proto_enabled;	/* Protocols enabled (see IC_xxx) */
extern int ic_set_manually;	/* IPconfig parameters set manually */

extern __be32 ic_myaddr;		/* My IP address */
extern __be32 ic_gateway;		/* Gateway IP address */

extern __be32 ic_servaddr;		/* Boot server IP address */

extern __be32 root_server_addr;	/* Address of NFS server */
extern u8 root_server_path[];	/* Path to mount as root */

#define IC_USE_DHCP    0x100	/* If on, use DHCP instead of BOOTP */

Annotation

• Immediate include surface: `linux/types.h`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
