  If filter_type not supported, eth_igb_filter_ctrl() will return
incorrect value.

OK, but I think this bug affects all stable release about 6 years before today.

I don't think so, since it is PMD internal ops, the real API 'rte_flow_ops_get'
always use RTE_ETH_FILTER_GENERIC. ;-)

eth_igb_filter_ctrl() called by rte_eth_dev_filter_ctrl(), if application
developer know how to use the parameter filter_type correctly, it's OK. 
otherwise he will get rte_eth_dev_filter_ctrl() return value is success
but actually is failed.

After check with Haiyue, we think the patch is still needed for LTS <= 19.11, so

Acked-by: Qi Zhang <qi.z.zhang@intel.com>

Applied to dpdk-next-net-intel.

Thanks

What is the status of this patch?
It seems it did not applied, and the status in the patchwork is "Superseded".

The patch is dropped during rebase, as the function eth_igb_filter_ctrl is removed at below code refectory 
http://patchwork.dpdk.org/project/dpdk/patch/20210321090002.595744-2-thomas@monjalon.net/

this is a mistake as we still need this to be captured in LTS
unfortunately, its too late to capture it as the refectory code is already applied to main tree.

@Luca Boccassi
Could you capture this patch as an LTS only one?

Thanks
Qi

Please rebase it on 20.11 and test it, and if it works send it to
