Hi all,

While openflow1.3 and up supports 4 byte long port numbers (see spec and 
OFPP_MAX)
(I'm also referring to messages such as multi part port description, packet out 
etc...), I've found out lately that
OVS and OVSDB support only 2 byte long port  numbers

root@IP20C:/root> ovs-vsctl add-port IP20C-2 alpha -- set interface alpha 
type=internal ofport_request=268443713
ovs-vsctl: constraint violation: 268443713 is not in the valid range 1 to 65279 
(inclusive)

even if I bypass ofport_request and use ofport directly, vswitch still doesn't 
accept 4 bytes for the port number
Is there any intension to change ofport_request type to unsigned integer in the 
future?

Thanks
Eyal
