480 | * | |
481 | * Solaris IFF_UP flag reflects only the primary interface as the | |
d62a17ae | 482 | * routing socket only sends IFINFO for the primary interface. Hence |
483 | * ~IFF_UP does not per se imply all the logical interfaces are also | |
5c78b3d0 | 484 | * down - which we only know of as addresses. Instead we must determine |
d62a17ae | 485 | * whether the interface really is up or not according to how many |
5c78b3d0 | 486 | * addresses are still attached. (Solaris always sends RTM_DELADDR if |
487 | * an interface, logical or not, goes ~IFF_UP). | |
488 | * | |
489 | * Ie, we mangle IFF_UP to *additionally* reflect whether or not there | |
490 | * are addresses left in struct connected, not just the actual underlying | |
491 | * IFF_UP flag. | |
492 | * | |
493 | * We must hence remember the real state of IFF_UP, which we do in | |
494 | * struct zebra_if.primary_state. | |
495 | * | |
496 | * Setting IFF_UP within zebra to administratively shutdown the | |
497 | * interface will affect only the primary interface/address on Solaris. | |
