[PATCH] examples/ipsec-secgw: fix zero address in ethernet header

[Rahul Bhansali]

During port init, src address stored in ethaddr_tbl is typecast
which violates the stric-aliasing rule and not reflecting
the updated source address in processed packets too.

Fixes: 6eb3ba0399 ("examples/ipsec-secgw: support poll mode NEON LPM lookup")
