Subject: [PATCH] examples/tep_term: fix L4 length

[ upstream commit 39f84786a23897596c42124c4416fc443bc9b688 ]

l4_len is not fixed, althrough mostly it is a fixed value,
but when guest using iperf to do some tests, the l4_len
will have another 12 bytes optional fields.

Fixes: 2bb43bd4350a ("examples/tep_term: add TSO offload configuration")
