The first patch fixes erspan metadata extraction issue from packet
header due to commit d350a823020e ("net: erspan: create erspan metadata
uapi header"). The commit moves the erspan 'version' in
'struct erspan_metadata' in front of 'struct erspan_md2' for later
extensibility, but breaks the existing metadata extraction code due
to extra 4-byte size 'version'. The second patch fixes the case where
tunnel device receives an erspan packet with different tunnel metadata
(ex: version, index, hwid, direction), existing code overwrites the
tunnel device's erspan configuration. The third patch fixes the bpf
tests due to the above patches.
