app/testpmd: fix error definition type
Checks
Commit Message
In "msg_type |= 0xc800", wider "51200" has high-order bits (0xc800)
that don't affect the narrower left-hand side.
This patch fixs coverity issue by changing the definition type of
"msg_type" from uint8_t to uint16_t.
Coverity issue: 373651
Fixes: 748530f0354e ("app/testpmd: support L2TPv2 and PPP protocol pattern")
