Package: ifenslave-2.6
Version: 1.1.0-20
Severity: normal
Dear Maintainer,
The primary master is not apply on the system because "sysfs primary" must be
call after "sysfs_add slaves".
As a workaround i have moved the call to the "setup_master" function after
"enslave_slaves" function.
I don't know if it is a good method but it seems to work correctly
Regards.
