Cannot set advskew back to 0
100%
Description
When leaving persistent CARP maintenance mode, the advskew is left at 254 on the running system, so it retains backup status when it shouldn't. advskew should be set back to its config-defined value after leaving persistent maintenance mode.

This seems to me to be a FreeBSD bug, setting advskew to 0 never works.. Setting it to 1 is possible though. Perhaps pfSense carp interfaces should use a minimum advskew value of 1 ?

That is correct, we're running the commands correctly to set it back to 0. The source of the issue is FreeBSD 10.1 won't set it back to 0, though any other value works.
I committed a work around to resolve this issue for the time being.

will leave this here to hopefully remove the workaround at some point once that upstream bug is fixed.

There still seems to be an issue here. On a current snapshot when I try to leave maintenance mode the skew is stuck at 254 on the LAN side, but it may be related to having IP Alias VIPs using the CARP VIP as their parent.
We probably should automatically set the skew to 1 when the user has it set to 0. 0 is supposed to be for emergency use, we should probably prevent that from being selected directly in the GUI. carp(4) and ifconfig(8) list 0 as being special and default, and 1 is the lowest user-configurable value.
