[dpdk-dev] [PATCH] net/enic: fix the filter type used for flow API

[Hyong Youb Kim <hyonkim@cisco.com>]

The filter type (struct filter_v2.type) should always be set to
FILTER_DPDK_1, when advanced filtering is enabled in
firmware. Otherwise, for some old firmware versions, the driver sets
it to FILTER_USNIC_IP, and attempts to install filters fail. This
behavior matches that of the now-removed flow director implementation
(enic_clsf.c).

Fixes: 26faa126d87e ("net/enic: flow API for NICs with advanced filters disabled")
