[dpdk-dev] [PATCH v3] net/ice: fix item number when pattern has ETH

[Wei Zhao <wei.zhao1@intel.com>]

When pattern has ETH, maybe it will contain
MAC and ethertype two kinds of lookup parameters,
so add more item number for memory malloc in order
to reserve one more memory slot for ETH which may
consume 2 lookup items.

Fixes: 24dc00c30907 ("net/ice: enable switch filter")
