Subject: datapath: Avoid possibility of negative 'n_ports' in struct odp_portvec.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1da3c6a0500a6dae270c918d5c85c60682ba6036;p=openvswitch

datapath: Avoid possibility of negative 'n_ports' in struct odp_portvec.

'n_ports' should never be negative so it's better to use an unsigned type.
