25cc7b9a11 doc: remove Intel PMD examples in flow bifurcation guide
Now this feature is no longer supported by kernel side, (i40e kernel
driver doesn't support it from v2.3.2 and ixgbe kernel driver isn't
guaranteed to support this feature as well in the future), so remove the
Intel PMD examples to avoid confusion.

8459f5ab32 net/ring: fix device pointer on allocation
When a net_ring device is allocated, its device pointer is not set
before calling rte_eth_dev_probing_finish, which is incorrect.

The following:
  commit 96cb19521147 ("net/ring: use EAL APIs in PMD specific API")
  commit a6992e961050 ("net/ring: set ethernet device field")

already fixed the same issue in 17.08, which was fine at the time.
Adding the hook rte_eth_dev_probing_finish() however created this bug,
as the eth_dev exposed when this hook is executed is expected to be
complete.

Remove the prior attempts to fix the issue in rte_pmd_ring_probe() and
write the pointer properly in do_eth_dev_ring_create().

In ixgbe_dev_link_update_share(), if the media type is fiber and the
link is down, a flag (IXGBE_FLAG_NEED_LINK_CONFIG) is set. A callback
to ixgbe_dev_setup_link_thread_handler() is scheduled which should
try to set up the link and clear the flag afterwards. This flag works
as a guard variable between threads.

To avoid potential race condition between threads, set the
IXGBE_FLAG_NEED_LINK_CONFIG flag only when there is no link thread
running.

When running testpmd with 10G interfaces on 10BaseT interface

This was identified to be caused by the setting of link as down

Also, the line rate was not being updated in device link params,

6b30428820 doc: refine ethernet and VLAN flow rule items
Specified pattern may be translated in different manner.
For example the pattern "eth / ipv4" can be translated to match
untagged packets only, since the pattern doesn't specify a VLAN item.
It can also be translated to match both tagged and untagged packets,
for the same reason.
This patch updates the rte_flow documentation to clearly specify the
required pattern to use.
For example:
To match tagged ipv4 packets, the pattern "eth / vlan / ipv4 / end"
should be used.
To match untagged ipv4 packets, the pattern "eth / ipv4 / end"
should be used.
To match all IPV4 packets, both tagged and untagged, need to apply
two rules with the patterns above.
To match both tagged and untagged packets of any type, the pattern
"eth / end" should be used.

5330b04297 net/iavf: fix link speed
If the PF driver does not support the new speed reporting capabilities
then use link_event instead of link_event_adv to get the speed.

6ebabb76a5 net/bnxt: fix possible stack smashing
We see a stack smashing as a result of defensive code missing. Once the
nb_pkts is less than RTE_BNXT_DESCS_PER_LOOP, it will be modified to
zero after doing a floor align, and we can not exit the following
receiving packets loop. And the buffers will be overwrite, then the
stack frame was ruined.

Fix the problem by adding defensive code, once the nb_pkts is zero, just
directly return with no packets.

c6611b77d0 net/netvsc: do not configure RSS if disabled
This fixes the problem where driver would not start if only
have a single Rx queue and multiple Txq. In that case, RSS
should stay disabled.

019a28912b net/netvsc: do RSS across Rx queue only
If number of tx queues is greater than the number of rx queues;
the driver ends up allocating more channels than rx queues.
The problem is that the RSS indirection table is programmed such
that some packets will end up on a channel that would never be
polled. The fix is to limit the RSS indirection table by number
of rx queues not channels.

81938ebb54 net/netvsc: manage VF port under read/write lock
With multiple channels, the primary channel may receive notification
that VF has been added or removed while secondary channel is in
process of doing receive or transmit.  Resolve this race by converting
existing vf_lock to a reader/writer lock.

Users of lock (tx/rx/stats) acquire for read, and actions like
add/remove acquire it for write.

Since VF notifications are handled as VMBUS notifications on the
primary channel (and not as hotplug). The channel should be checked
before deciding to use VF for Rx or Tx.
