Hi Sujai,
I reverified the issue, and with the patch, I am now getting the correct
error about insufficient space, when attempting to add to many rules.
The error you’re encountering might be caused by a different issue.
Could you please test it again or send me offline the set of rules you
are adding? It seems to be working fine on my side.
Regards,
Martyna

Hi,
I tried to add tc rules to the HW beyond the maximum limit and still noticing
the below error message instead of error message mentioned in the patch.
[root@dell-cnv-sut ~]# tc filter add dev ens5f0np0 ingress protocol ip prio 0
flower skip_sw dst_mac 00:f0:01:00:00:0E action mirred egress redirect dev
ens5f0npf0vf0
Error: ice: Unable to add filter due to error.
We have an error talking to the kernel
[root@dell-cnv-sut ~]# tc filter show dev ens5f0np0 root | grep -c in_hw
16306
Please check it.
Thanks,
Sujai B

When adding a rule to switch through tc, if the operation fails due to
not enough free recipes (-ENOSPC), provide a clearer error message:
"Unable to add filter: insufficient space available."
This improves user feedback by distinguishing space limitations from
other generic failures.
