When we add some long switch rule, we need check the
number of final recipe number, if it is large than
ICE_MAX_CHAIN_RECIPE, we should refuse this rule.
For example:
"flow create 0 ingress pattern eth / ipv6
src is CDCD:910A:2222:5498:8475:1111:3900:1536
dst is CDCD:910A:2222:5498:8475:1111:3900:2022
tc is 3 / udp dst is 45 / end actions queue index 2 / end"
This rule will consume 6 recipe, if it is not refused, it
will cause the following code over write of lkup_indx and mask.
LIST_FOR_EACH_ENTRY(entry, &rm->rg_list, ice_recp_grp_entry,
l_entry) {
last_chain_entry->fv_idx[i] = entry->chain_idx;
buf[recps].content.lkup_indx[i] = entry->chain_idx;
buf[recps].content.mask[i++] = CPU_TO_LE16(0xFFFF);
..........
}
