Denys Vlasenko	002d6ee46d	ifplugd: split -a into -a and -A, latter disables upping in iface creation -a meant both "don't up iface before each link detection" and "don't up iface when it newly appears". But they are not the same. I have a dock station where eth1 appears when I attach the notebook to it (looks like it's hanging off a USB bus). IOW: appearance of this interface is functionally equivalent to attaching ethernet cable. ifplugd meant to be able to automatically handle this case. Currently, with -a, it couldn't: newly appearing iface stayed down, user had to manually up it. function old new delta packed_usage 34253 34296 +43 .rodata 104876 104877 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 44/0) Total: 44 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2022-04-30 14:33:14 +02:00
