[PATCH v1 1/1] net: fix inner L2 length for GRE and NVGRE

[Rakesh Kudurumalla]

Inner l2 length needs to be updated to include GRE and NVGRE
headers. Not updating this would cause failures for applications
which would be expecting l2_len field to be valid for
inner checksum offload cases.

Fixes: 76730c7b9b5a ("app/testpmd: use packet type parsing API")
