Log Message:
-----------
flow: Support extra padding length.
Although not required, padding can be optionally added until
the packet length is MTU bytes. A packet with extra padding
currently fails sanity checks.
Vulnerability: CVE-2020-35498
Fixes: fa8d9001a624 ("miniflow_extract: Properly handle small IP packets.")
