When creating the dr rule of meter, the matcher which
struct is "struct mlx5dv_dr_matcher" should not be
shared, if shared, mlx5dv_dr_rule_create will return
NULL. We can't install more metering offload actions.
The call tree (rdma-core-47mlnx1 OFED 4.7-3.2.9):
* dr_rule_handle_ste_branch
* dr_rule_create_rule_nic
* dr_rule_create_rule_fdb
* dr_rule_create_rule
* mlx5dv_dr_rule_create
In the dr_rule_handle_ste_branch, if ste is not used,
mlx5dv_dr_rule_create will return rule, if the ste is
used, and the ste is the last in the rule, mlx5dv_dr_rule_create
will return NULL.
dr_rule_handle_ste_branch:
if dr_ste_not_used_ste
dr_rule_handle_empty_entry
else
dr_rule_find_ste_in_miss_list
dr_ste_is_last_in_rule: if so return NULL and set errno = EINVAL;
Fixes: 9ea9b049a960 ("net/mlx5: split meter flow")

Hello Tonghao,
Could you please explain much detail about your issue scenario?
If I understand correctly, you are trying to create two flows with the two same match criteria?
Example from testpmd just like that:
add port meter profile srtcm_rfc2697 0 24 65536 32768 0
create port meter 0 0 24 yes G Y D 0xffff 1 0
flow create 0 ingress pattern eth / end actions jump group 1 / end
flow create 0 priority 3 group 1 ingress pattern eth / end actions meter mtr_id 0 / queue index 0 / end
flow create 0 priority 3 group 1 ingress pattern eth / end actions meter mtr_id 0 / queue index 1 / end
Then the third flow will report "hardware refuses to create flow: Invalid argument".
Please correct me if I'm wrong.
And better to give the issue reproduce method via testpmd cmdline.
Thanks
SuanmingMou

./testpmd -l 0-3 -n 4 -w 0000:82:00.0 -w 0000:82:00.1 -- -i
--portmask=0x3 --rxq=2 --nb-cores=2
add port meter profile srtcm_rfc2697 0 100 1024 1024 0
add port meter profile srtcm_rfc2697 0 101 2048 2048 0
create port meter 0 100 100 yes G Y D 0xffff 1 0
create port meter 0 101 101 yes G Y D 0xffff 1 0
flow create 0 ingress pattern eth / end actions jump group 1 / end
flow create 0 group 1 priority 3 ingress pattern eth / ipv4 dst is
1.1.1.100 / end actions meter mtr_id 100 / queue index 0 / end
The one of commands below will run fail:
flow create 0 group 1 priority 3 ingress pattern eth / ipv4 dst is
1.1.1.200 / end actions meter mtr_id 101 / queue index 1 / end
flow create 0 group 1 priority 3 ingress pattern eth / ipv4 dst is
1.1.1.200 / tcp dst is 80 / end actions meter mtr_id 101 / queue
index 1 / end
flow create 0 group 1 priority 3 ingress pattern eth / ipv4 / tcp dst
is 80 / end actions meter mtr_id 101 / queue index 1 / end
Caught error type 1 (cause unspecified): hardware refuses to create
flow: Invalid argument
And with this patch, it works fine.
