| 42 | * Structure that must be initialized for a diskless nfs client. |
| 43 | * This structure is used by nfs_mountroot() to set up the root and swap |
| 44 | * vnodes plus do a partial ifconfig(8) and route(8) so that the critical |
| 45 | * net interface can communicate with the server. |
| 46 | * Whether or not the swap area is nfs mounted is determined |
| 47 | * by the value in swdevt[0]. (equal to NODEV --> swap over nfs) |
| 48 | * Currently only works for AF_INET protocols. |
| 49 | * NB: All fields are stored in net byte order to avoid hassles with |
| 50 | * client/server byte ordering differences. |
