Subject: [PATCH] app/testpmd: fix mpls encap ipv4 version and ihl
According to ietf rfc791 (see [1])
"The Version field indicates the format of the
internet header."
"Internet Header Length (ihl) is the length of the
internet header in 32 bit words, and thus points
to the beginning of the data. Note that
the minimum value for a correct header is 5."
Having version and ihl set to 0 would result in a
corrupted/incorrect encapsulating packet for MPLS,
this commit sets these fields to 4 and 5 respectively
as the default value.
[1] https://tools.ietf.org/html/rfc791
Fixes: 3e77031be855 ("app/testpmd: add MPLSoGRE encapsulation")
Fixes: a1191d39cb57 ("app/testpmd: add MPLSoUDP encapsulation")
