| 6 | * Allow an NFS filesystem to be mounted as root. The way this works is: | |
| 7 | * (1) Use the IP autoconfig mechanism to set local IP addresses and routes. | |
| 8 | * (2) Handle RPC negotiation with the system which replied to RARP or | |
| 9 | * was reported as a boot server by BOOTP or manually. | |
| 10 | * (3) The actual mounting is done later, when init() is running. | |

| 13 | * Changes: | |
| 14 | * | |
| 15 | * Alan Cox : Removed get_address name clash with FPU. | |
| 16 | * Alan Cox : Reformatted a bit. | |
| 17 | * Gero Kuhlmann : Code cleanup | |
| 18 | * Michael Rausch : Fixed recognition of an incoming RARP answer. | |
| 19 | * Martin Mares : (2.0) Auto-configuration via BOOTP supported. | |
| 20 | * Martin Mares : Manual selection of interface & BOOTP/RARP. | |
| 21 | * Martin Mares : Using network routes instead of host routes, | |
| 22 | * allowing the default configuration to be used | |
| 23 | * for normal operation of the host. | |
| 24 | * Martin Mares : Randomized timer with exponential backoff | |
| 25 | * installed to minimize network congestion. | |
| 26 | * Martin Mares : Code cleanup. | |
| 27 | * Martin Mares : (2.1) BOOTP and RARP made configuration options. | |
| 28 | * Martin Mares : Server hostname generation fixed. | |
| 29 | * Gerd Knorr : Fixed wired inode handling | |
| 30 | * Martin Mares : (2.2) "0.0.0.0" addresses from command line ignored. | |
| 31 | * Martin Mares : RARP replies not tested for server address. | |
| 32 | * Gero Kuhlmann : (2.3) Some bug fixes and code cleanup again (please | |
| 33 | * send me your new patches _before_ bothering | |
| 34 | * Linus so that I don' always have to cleanup | |
| 35 | * _afterwards_ - thanks) | |
| 36 | * Gero Kuhlmann : Last changes of Martin Mares undone. | |
| 37 | * Gero Kuhlmann : RARP replies are tested for specified server | |
| 38 | * again. However, it's now possible to have | |
| 39 | * different RARP and NFS servers. | |
| 40 | * Gero Kuhlmann : "0.0.0.0" addresses from command line are | |
| 41 | * now mapped to INADDR_NONE. | |
| 42 | * Gero Kuhlmann : Fixed a bug which prevented BOOTP path name | |
| 43 | * from being used (thanks to Leo Spiekman) | |
| 44 | * Andy Walker : Allow to specify the NFS server in nfs_root | |
| 45 | * without giving a path name | |
