While calling the response msg callback, the callback could trigger
irq handler which could take too long to cause the rcu stall issue.
and rcu_lock is not needed in this case, because there is nothing
to be protected while callback is running.

for outer rule. In this fix, we check respective rule_flags for
setting the src_port to 0, only for outer rule.

- __udp4_lib_lookup matches parameter "daddr" with local socket address.
Hence, need to pass local address as the destination.
- UDP checksum should be skipped for zero checksum value.
- UDP socket can be used for control packets that need to be passed to userspace.
Hence, SFE can't drop those packets and has to resubmit them into Linux stack.

This is required to re-inject the packets to the stack,
if L2 acceleration is not enabled for the flows. By doing
this check, first pass of the flow with the L2 interface will be
skipped and the flow will come to SFE with the L3 interface in the
second pass.
