Subject: [PATCH] examples/tep_term: fix port id check
Coverity reported lots of out-of-bounds in function
vxlan_link, these issues should happen when index
port_id evaluates to 2, cause size of arrays is
2 in structure.
Fix this issue by modifying judgement condition, make
sure port_id is less than 2.
Coverity issue: 107121, 107122, 107123, 107124, 107125
Fixes: 4abe471ed6fc ("examples/tep_term: implement VXLAN processing")
