net/enic: fix inner packet matching

Inner packet matching is currently buggy in many cases.

1. Mishandling null spec ("match any").
The copy_item functions do nothing if spec is null. This is incorrect,
as all patterns should be appended to the L5 pattern buffer even for
null spec (treated as all zeros).

2. Accessing null spec causing segfault.

3. Not setting protocol fields.
The NIC filter API currently has no flags for "match inner IPv4, IPv6,
UDP, TCP, and so on". So, the driver needs to explicitly set EtherType
and IP protocol fields in the L5 pattern buffer to avoid false
positives (e.g. reporting IPv6 as IPv4).

Instead of keep adding "if inner, do something differently" cases to
the existing copy_item functions, introduce separate functions for
inner packet patterns and address the above issues in those

flow create 0 ingress pattern ... actions mark id 0 / queue index 0 / end

The problem has to do with mapping mark IDs (32-bit) to NIC filter

rejected. The firmware reserves filter ID 0 for filters that do not
mark (e.g. steer w/o mark). And, the driver reserves 0xffff for the

It is possible to simply reject mark ID 0 as unsupported. But, 0 is
commonly used (e.g. OVS-DPDK and VPP). So, when adding a filter, set
filter ID = mark ID + 1 to support mark ID 0. The receive handler

The existing code (copy_fltr_v2) has two bugs.

1. It sets the protocol number (132) in the match value, but not the
mask. The mask remains 0, so the match becomes a wildcard match. The
NIC ends up matching all protocol numbers (i.e. thinks non-SCTP

2. It modifies the input argument (rte_eth_fdir_input). The driver
tracks filters using rte_hash_{add,del}_key(input). So, addding
(RTE_ETH_FILTER_ADD) and deleting (RTE_ETH_FILTER_DELETE) must use the
same input argument for the same filter. But, overwriting the protocol
number while adding the filter breaks this assumption, and causes
delete operation to fail.

So, set the mask as well as protocol value. Do not modify the input
argument, and use const in function signatures to make the intention
clear. Also move a couple function declarations to enic_clsf.c from

bus/vdev: fix hotplug twice

In case vdev was already probed, it shouldn't be probed again,
and it should return -EEXIST as error.
There are some checks in vdev_probe() and insert_vdev(),

The check is moved in vdev_probe_all_drivers() which is called
