Hi List,
investigating a problem with an snmp software for linux, i was wondering why the kernel allocates a new ifindex Number, even if the old one is still available. For example, if i unload a network driver module, and reload it, it has a different ifindex.
Looking at the function dev_new_index (line 2620 in net/core/dev.c) there is a line 'static int ifindex'. Is there any special reason why this variable is static, and the list is not traversed from the beginning, so that the first free ifindex will be used?
Best regards,
Sven. [unhandled content-type:application/pgp-signature] | |
