commit 8f036fd34011bbf138815b21e2ef4c9760a5e0e6 Author: watanabe isao <[email protected]> Date: Tue Jun 30 14:36:40 2015 +0900 Mitigate restriction for fixed ips per dhcp port When number of fixed ips per dhcp port exceeds max_fixed_ips_per_port, a dhcp resync will be triggered. The bug report stated how simply this issue can be triggered. Moreover, "max_fixed_ips_per_port" value should be used for non-DHCP port only and DHCP port is not affected by this parameter.
