f7e95215ac net/mlx5: extend switch domain searching range
With bonding configurations the switch domain may be shared
between multiple PCI devices, we should search the switch
sibling devices within the entire set of present ethernet
devices backed by the mlx5 PMD.

f07341e7ae net/mlx5: update source and destination vport translations
There new kernel/rdma_core [1] supports matching on metadata
register instead of vport field to provide operations over
VF LAG bonding configurations. This patch provides correct
translations for flow matchers and destination port actions
if united E-Switch (for VF LAG) is configured and/or new vport
matching mode is engaged.

2e569a3703 net/mlx5: add VF LAG mode bonding device recognition
The Mellanox NICs starting from ConnectX-5 support LAG over
NIC ports internally, implemented by the NIC firmware and hardware.
The multiport NIC presents multiple physical PCI functions (PF),
with SR-IOV multiple virtual PCI functions (VFs) might be presented.
With switchdev mode the VF representors are engaged and PFs and their
VFs are connected by internal E-Switch feature. Each PF and related VFs
have dedicated E-Switch and belong to dedicated switch domain.

If NIC ports are combined to support NIC the kernel drivers introduce
the single unified Infiniband multiport devices, and all only one
unified E-Switch with single switch domain combines master PF
all all VFs. No extra DPDK bonding device is needed.

b67b4ecbde net/mlx5: skip table zero to improve insertion rate
E-switch tables one and above provide higher insertion rate
than table zero, as well as enhanced functionality.

This patch adds a mechanism to utilize these advantages, by creating
a default rule on port start, which directs all packets from e-switch
table zero to table one.
Other flow rules, requested for group n, will be created in
e-switch table n+1.
Jump action to e-switch group n will be created to group n+1.

Utility function mlx5_flow_group_to_table() is added to translate the
rte_flow group value to HW table value, and is called by PMD flow
engine on flow rule validation and creation.

c9333f457e net/mlx5: fix netlink RDMA socket callback routine
The mlx5 PMD uses Netlink socket to communicate with Infiniband
devices kernel drivers to perform some control and setup operations.
The kernel drivers send the information back to the user mode
with Netlink messages which are processed in libnl callback routine.
This routine perform reply message (or set of messages) processing
and returned the processing result in ibindex field of provided
context structure (of mlx5_nl_ifindex_data type). The zero ibindex
value meant an error of reply message processing. It was found in
some configurations the zero is valid value for ibindex and error
was wrongly raised. To avoid this the new flags field is provided
in context structure, attribute processing flags are introduced
and these flags are used to decide whether no error occurred and
valid queried values are returned.

For the rte_flow_action_raw_encap, the header definition for
encapsulation must be available, otherwise it will lead to crash on some
OFED versions and logically it should be rejected.

4dec9c79c2 net/mlx5: fix completion request for multi-segment
The copying of sent mbufs pointers might be deferred to the end of
tx_burst() routine to be copied in one call of rte_memcpy.
For the multi segment packets this optimization is not applicable,
because number of packets does not match with number of mbufs and
we do not have linear array of pointers in pkts parameter.

The completion request generating routine wrongly took into account
the inconsistent (for multi-segment packets) deferred pointer copying.

0e3d0525b2 net/mlx5: fix memory event callback list
The shared Infiniband device context should be included
into memory event callback list only once on context creation,
and removed from the list only once on context destroying.
Multiple insertions of the same object caused the infinite
loop on the list processing.

c3318f529c net/mlx5: fix RSS expand for IP-in-IP
The RSS expand function for IP-in-IP tunnel type is missed,
which leads to create following flow failed:

   flow create 0 ingress pattern eth / ipv4 proto is 4 /
        ipv4 / udp / end actions rss queues 0 1 end level 2
	types ip ipv4-other udp ipv4 ipv4-frag end /
	mark id 221 / count / end

In order to make RSS expand function working correctly,
now the way to check whether a IP tunnel existing is to
check whether there is the second IPv4/IPv6 item and whether the
first IPv4/IPv6 item's next protocl is IPPROTO_IPIP/IPPROTO_IPV6.
For example:
  ... pattern eth / ipv4 proto is 4 / ipv4 / ....

1f1eb0949c net/mlx5: fix UDP checksum zeroing
Function flow_dv_zero_encap_udp_csum() uses a while loop to iterate
over vlan items in flow rule.
Pointer next_hdr is incremented to the next item before it is used,
so the first item is skipped.

This patch moves the incrementing of next_hdr to the correct place.

6fd05da9ef net/mlx5: fix link speed info when link is down
When the link is down, the link speed returned by ethtool is
UINT32_MAX and the link status is 0.

In this case, the DPDK ethdev link speed should be set to
ETH_SPEED_NUM_NONE.
Otherwise since link speed is non-zero but link status is zero, this
is an inconsistent situation and -EAGAIN is returned, which is not right.

If the minimal inline data are required the data inline feature
must be engaged. There were the incorrect settings enabling the
entire small packet inline (in size up to 82B) which may result
in sending rate declining if there is no enough cores. The same
problem was raised if inline was enabled to support VLAN tag
insertion by software.
