Originally, the value of field_selector for IPV4_FRAG header hdr1 is
the same as the previous header hdr2. For IPv4 packets, field_selector
for hdr2 can be any value between 0 and 4, depending on the selected
field. Actually, this value for IPV4_FRAG should be constant 0,
which denotes the field packet ID.
This patch adds an assignment to hdr1->field_selector to make sure that
it is always 0.
