Subject: ofproto: Maximum value of "int" is INT_MAX, not UINT32_MAX.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=392804e7ee2753cea831503fbdbafc2d7780862a;p=openvswitch

ofproto: Maximum value of "int" is INT_MAX, not UINT32_MAX.

This bug seems to be dormant at the moment, since the -1 gets passed
through unchanged to do_send_packet_in() and then to make_packet_in()
and then gets converted to SIZE_MAX as part of the MIN invocation in that
function.  It is still better to fix it.
