net: move ip_packet_offload and ipv6_packet_offload to net_hotdata
These structures are used in GRO and GSO paths. v2: ipv6_packet_offload definition depends on CONFIG_INET Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Reviewed-by: David Ahern <dsahern@kernel.org> Link: https://lore.kernel.org/r/20240306160031.874438-7-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
