300 | * | |
301 | * Solaris IFF_UP flag reflects only the primary interface as the | |
302 | * routing socket only sends IFINFO for the primary interface. Hence | |
303 | * ~IFF_UP does not per se imply all the logical interfaces are also | |
304 | * down - which we only know of as addresses. Instead we must determine | |
305 | * whether the interface really is up or not according to how many | |
306 | * addresses are still attached. (Solaris always sends RTM_DELADDR if | |
307 | * an interface, logical or not, goes ~IFF_UP). | |
308 | * | |
309 | * Ie, we mangle IFF_UP to *additionally* reflect whether or not there | |
310 | * are addresses left in struct connected, not just the actual underlying | |
311 | * IFF_UP flag. | |
312 | * | |
313 | * We must hence remember the real state of IFF_UP, which we do in | |
314 | * struct zebra_if.primary_state. | |
315 | * | |
316 | * Setting IFF_UP within zebra to administratively shutdown the | |
317 | * interface will affect only the primary interface/address on Solaris. | |
