On the net-next branch include/linux/rtnetlink.h now has TCA_CHAIN, and everything
builds fine.  You may have local changes or be using different includes

$ git grep TCA_CHAIN
include/linux/rtnetlink.h:      TCA_CHAIN,
tc/tc_filter.c:         addattr32(&req.n, sizeof(req), TCA_CHAIN, chain_index);
tc/tc_filter.c: if (tb[TCA_CHAIN]) {
tc/tc_filter.c:         __u32 chain_index = rta_getattr_u32(tb[TCA_CHAIN]);
tc/tc_filter.c:         addattr32(&req.n, sizeof(req), TCA_CHAIN, chain_index);
tc/tc_filter.c:         addattr32(&req.n, sizeof(req), TCA_CHAIN, chain_index);
