When filtering on the member interfaces of the bridge tell if_bridge to send locally destined packets as coming from the member itself. This should fix some reported issues on Ticket #729.

Be more correct and do the same checks for RXCSUM capabilities as is done for TXCSUM one.

Ticket #88. Correctly use the parameter returned from link_interface_to_bridge to actually set the flags on the interface being configured the same as the bridge. While here simplify gre/gif handling too.

Check if this variable is empty before using, since if it's null/empty, it will come back true when we don't want that.

Do not use a monitor address from a load balancer pool as the monitor IP for a connection. This can lead to incorrect configurations. Some 1.2
configurations use load balancer pools as a subtitute for a gateway since that option was not available then.

Invert the is_array() check as this incorrectly unsets the gateway array leaving the system unreachable

Follow the restored username as the logged in user when upgrading a config. Otherwise you can get access errors if you need to do an interface reassignment.

Create a valid apinger configuration file for targets that are down during creation.

Use cp -p to preserve permissions (exec)

Save the old shutdown binary in an attempt to smooth a firmware upgrade that crosses to/from 32/64-bit.
