c961566c82 ixgbe: fix releasing queues twice when detaching VF
Releasing the rx and tx queues is already done in ixgbe_dev_close()
so it does not need to be done in eth_ixgbevf_dev_uninit().

a379430126 ixgbe: fix VF Rx/Tx function assignment
For the secondary process of DPDK to initialize ixgbevf, it will always
use the simple RX function or LRO RX function, and this behavior is not
the same RX/TX function selection logic as it is for the primary process.
Use the ixgbe_set_tx_function and ixgbe_set_rx_function to select the
RX/TX function when secondary process calls the init function for eth dev.

6be3dfec31 ixgbe: support link speed auto-negotiation on X550em_x
Normally the auto-negotiation is supported by FW. SW need not care about
that. But on x550em_x, FW doesn't support auto-neg. As the x550em_x ports
are 10G, if we connect the port will a peer which is 1G, the link will
always be down.
We need support auto-neg by SW to avoid this link down issue. As we already
have the code to handle the link speed setting, what we need is a trigger.
When the advertised link speed changes, a PHY interruption will be
triggered. So, we should handle this interrupt and call ixgbe_handle_lasi
to set the link speed correctly.

Please be aware it's working when auto-neg is on. If the auto-neg of the
peer port is turned off and its speed is indicated manually, we should also
set the speed of our own port manually.

72dec9e37a ixgbe: support multicast promiscuous mode on VF
Add multicast promiscuous mode support on ixgbe VF driver.

Please note if we want to use this promiscuous mode, we need both PF
and VF driver to support it. The reason is this VF feature is
configged on PF.
If use kernel PF driver + dpdk VF driver, make sure kernel PF driver
support VF multicast promiscuous mode. If use dpdk PF + dpdk VF,
better make sure PF driver is the same version as VF.

e4f4722c14 ixgbe/base: abstract out link read/write
It's more valuable to abstract the link read/write interface. As such,
change the following method names, and add them to a new link info
structure:
  read_i2c_combined               => read_link
  read_i2c_combined_unlocked      => read_link_unlocked
  write_i2c_combined              => write_link
  write_i2c_combined_unlocked     => write_link_unlocked

This will allow X550EM_a to override these methods for MDIO access
while X550EM_x provides methods to use I2C combined access.
Initially the structure is just method pointers and a bus
address.

Two functions involved in combined I2C accesses were moved from
ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry
out the combined I2C accesses were left in ixgbe_phy.c because
they share some functions with other I2C methods.

0cf7c6a6f3 ixgbe/base: set MDIO speed after MAC reset
The MDIO clock speed must be reconfigured after the MAC reset.
The MDIO clock speed becomes invalid, therefore the driver reads
invalid PHY register values. The driver now set the MDIO clock
speed prior to initializing PHY ops and again after the MAC reset.

As now the MDIO speed gets set in more than one place, make a
function for it so it will always be done correctly.

e2f368a4bf ixgbe/base: fix setting flow director flag twice
Do not set FDIRCTRL.DROP_NO_MATCH in ixgbe_init_fdir_perfect_82599(),
this bit is already set in ixgbe_set_fdir_drop_queue_82599() which
makes more sense for drivers that call that function.

This resolves an issue where packets were being dropped when switching
to perfect filters mode.

Setting this bit makes no sense in perfect filters mode for the
driver as we do not want to route all packets that don't match an FDIR
rule to a single queue and instead fall back to RSS.
Drivers that need this bit set can call ixgbe_set_fdir_drop_queue_82599()
and the ones that don't, can preserve the old behavior.

4a41c17dba igb: set default thresholds based on MAC type
This brings the DPDK igb driver inline with the behavior used by
the current Linux driver. The IGB hardware has several different
MAC types and the threshold values that work vary based on the hardware.

Since DPDK 1.8 it has been up to devices to provide the correct default
configuration parameter. But the igb driver gives values that are broken
on some devices, and always causes a warning message at startup.

Please test this on real hardware, I don't have the luxury of a

An introduction of E-tag:
It's defined in IEEE802.1br. Please reference this website,
http://www.ieee802.org/1/pages/802.1br.html.

A brief description.
E-tag means external tag, and it's a kind of l2 tunnel. It means a
tag will be inserted in the l2 header. Like below,
   |31            24|23           16|15         8|7           0|
  0|                   Destination MAC address                 |
  4|     Dest MAC address(cont.)    |     Src MAC address      |
  8|                  Source MAC address(cont.)                |
 12| E-tag Etherenet type (0x893f)  |      E-tag header        |
 16|                    E-tag header(cont.)                    |
 20|   VLAN Ethertype(optional)     |   VLAN header(optional)  |
 24|         Original type          |         ......           |
...|                              ......                       |
The E-tag format is like below,
   |0                    15|16   18|19 |20                   31|
   |   Ethertype - 0x893f  | E-PCP |DEI|   Ingress E-CID_base  |

   |32  33|34 35|36      47|48         55    |56             63|
   |  RSV | GRP |E-CID_base|Ingress_E-CID_ext|    E-CID_ext    |

The Ingess_E-CID_ext and E-CID_ext are always zero for endpoints
and are effectively reserved.

The more details of E-tag is in IEEE 802.1BR. 802.1BR is used to
replace 802.1Qbh. 802.1BR is a standard for Bridge Port Extension.
It specifies the operation of Bridge Port Extenders, including
management, protocols, and algorithms. Bridge Port Extenders
operate in support of the MAC Service by Extended Bridges.
The E-tag is added to l2 header to identify the VM channel and
the virtual port.

c7a4ff8072 i40e: fix overflow
The array 'ptype_table' was defined in depth of 'UINT8_MAX' which
is 255, while the querying index could be from 0 to 255. The issue
can be fixed with expanding the array to one more element.

19b16e2f64 ethdev: add vlan type when setting ether type
In order to set ether type of VLAN for single VLAN, inner
and outer VLAN, the VLAN type as an input parameter is added
to 'rte_eth_dev_set_vlan_ether_type()'.
In addition, corresponding changes in e1000, ixgbe and i40e
are also added.

It is an ABI break but ethdev library is already bumped for 16.04.

ac5e1d838d virtio: skip error when probing kernel managed device
virtio PMD could use IO port to configure the virtio device without
using UIO/VFIO driver in legacy mode.

There are two issues with previous implementation:
1) virtio PMD will take over the virtio device(s) blindly even if not
intended for DPDK.
2) driver conflict between virtio PMD and virtio-net kernel driver.

This patch checks if there is kernel driver other than UIO/VFIO managing
the virtio device before using port IO.

If legacy_virtio_resource_init fails and kernel driver other than
VFIO/UIO is managing the device, return 1 to tell the upper layer we
don't take over this device.
For all other IO port mapping errors, return -1.

Note than if VFIO/UIO fails, now we don't fall back to port IO.

d6b324c00f mbuf: get DMA address
Macros RTE_MBUF_DATA_DMA_ADDR and RTE_MBUF_DATA_DMA_ADDR_DEFAULT
are defined in each PMD driver file. Convert macros to inline
functions and move them to common lib/librte_mbuf/rte_mbuf.h file.
PMD drivers include rte_mbuf.h file directly/indirectly hence no
additioanl header file inclusion is necessary.
