[dpdk-dev] [PATCH] net/i40e: fix FDIR input set conflict

[Beilei Xing <beilei.xing@intel.com>]

The first FDIR rule for some PCTYPE will configure input set and
create flow, the following flows must use the same input set,
otherwise will cause input set conflict and fail to create flow.
But if creating the first rule after flow flush, input set should
be re-configured.

Fixes: 42044b69c67d ("net/i40e: support input set selection for FDIR")
