When building qemu with GCC 11, compiling eth.c file produce following warning: warning: array subscript 'struct ip6_ext_hdr_routing[0]' is partly outside array bounds of 'struct ip6_ext_hdr[1]' [-Warray-bounds] This caused by retyping from ip6_ext_hdr to ip6_ext_hdr_routing that has more attributes. As this usage is expected, suppress the warning temporarily through the function using this retyping.
