[dpdk-users] problem in setting mask for ntuple filters

[Alex Salig]

I want to set a mask other than UINT32_MAX for IP address field of a
RTE_ETH_FILTER_NTUPLE. But I get "Invalid argument" error.
I checked the code and found out that in the implementation of this filter,
the mask value is checked to be either UINTxx_MAX or 0? Why?
