336 | * | |
337 | * Solaris IFF_UP flag reflects only the primary interface as the | |

339 | * ~IFF_UP does not per se imply all the logical interfaces are also | |
5c78b3d0 | 340 | * down - which we only know of as addresses. Instead we must determine |
d62a17ae | 341 | * whether the interface really is up or not according to how many |
5c78b3d0 | 342 | * addresses are still attached. (Solaris always sends RTM_DELADDR if |
343 | * an interface, logical or not, goes ~IFF_UP). | |
344 | * | |
345 | * Ie, we mangle IFF_UP to *additionally* reflect whether or not there | |
346 | * are addresses left in struct connected, not just the actual underlying | |
347 | * IFF_UP flag. | |
348 | * | |
349 | * We must hence remember the real state of IFF_UP, which we do in | |
350 | * struct zebra_if.primary_state. | |
351 | * | |
352 | * Setting IFF_UP within zebra to administratively shutdown the | |
