This appears to fix error, the warning is still present:
progs/test_tc_tunnel.c: In function '__encap_ipv4':
progs/test_tc_tunnel.c:228:31: warning: taking address of packed member of
'struct v4hdr' may result in an unaligned pointer value
[-Waddress-of-packed-member]
228 | set_ipv4_csum((void *)&h_outer.ip);
