Subject: types: Change ofp_port_t from uint16_t to uint32_t.
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=117d72495467efaa3eb7e7e4f7d110cd1223b967;p=cascardo%2Fovs.git

types: Change ofp_port_t from uint16_t to uint32_t.

This fixes several tests that failed on big-endian systems because "union
flow_in_port" overlays an ofp_port_t and odp_port_t and in some cases it
is not easy to determine which one is in use.

This commit also fixes up a few places where this broke other code.
