Compile with -Werror and -Wcast-align:
lib/netdev-offload-dpdk.c:578:30: error: cast increases required alignment
of target type [-Werror=cast-align]
578 | ipv6_format_addr((struct in6_addr *) &set_ipv6->ipv6_addr, s);
| ^
Fix it.
Fixes: b6207b1d2711 ("netdev-offload-dpdk: Support offload of set IPv6
actions.")
