This patch implemented the ops of adding and removing mac
address in i40evf driver. Functions are assigned like:
.mac_addr_add = i40evf_add_mac_addr,
.mac_addr_remove = i40evf_del_mac_addr,
To support multiple mac addresses setting, this patch also
extended the mac addresses adding and deletion when device
start and stop. Each VF can have a maximum of 64 mac
addresses.

VEB switching feature for i40e is used to enable the switching between the
VSIs connect to the virtual bridge. The old implementation is setting the
virtual bridge mode as VEPA which is port aggregation. Enable the switching
ability by setting the loop back mode for the specific VSIs which connect
to PF or VFs.
VEB/VSI/VEPA are concepts not specific to the i40e HW, the concepts are
from 802.1qbg spec
IEEE EVB tutorial:
http://www.ieee802.org/802_tutorials/2009-11/evb-tutorial-draft-20091116_v09.pdf
VEB: a virtual switch can forward the packet based on the specific match
field.
VSI: a virtual interface connect between the VEB/VEPA and virtual machine.
VEPA: a virtual Ethernet port aggregator will upstream the packets from
VSI to the LAN port.

Previously, DCB(Data Center Bridging) is only enabled on PF,
queue mapping and BW configuration is only done on PF.
This patch enables DCB for VMDQ VSIs(Virtual Station Interfaces)
by following steps:
1. Take BW and ETS(Enhanced Transmission Selection)
configuration on VEB(Virtual Ethernet Bridge).
2. Take BW and ETS configuration on VMDQ VSIs.
3. Update TC(Traffic Class) and queues mapping on VMDQ VSIs.
To enable DCB on VMDQ, the number of TCs should not be larger than
the number of queues in VMDQ pools, and the number of queues per
VMDQ pool is specified by CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VM
in config/common_* file.

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.

It's more valuable to abstract the link read/write interface. As such,

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

out the combined I2C accesses were left in ixgbe_phy.c because

1. edesc->size is not initialized properly in mpipe_do_xmit() and could
cause buffer leak or corruption when HW buffer return is used.
2. Check the 'idesc.be' error bit in mpipe_recv_flush() to make sure

On X550, as required by datasheet, E-tag packets are not expected
when double VLAN are used. So modify the register PFVTCTL after
enabling double VLAN to select pool by MAC but not MAC or E-tag.
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.

There are two issues with previous implementation:

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.

Modern (v1.0) virtio pci device defines several pci capabilities.
Each cap has a configure structure corresponding to it, and the
cap.bar and cap.offset fields tell us where to find it.
Firstly, we map the pci resources by rte_eal_pci_map_device().
We then could easily locate a cfg structure by:
cfg_addr = dev->mem_resources[cap.bar].addr + cap.offset;
Therefore, the entrance of enabling modern (v1.0) pci device support
is to iterate the pci capability lists, and to locate some configs
we care; and they are:
- common cfg
For generic virtio and virtqueue configuration, such as setting/getting
features, enabling a specific queue, and so on.
- nofity cfg
Combining with `queue_notify_off' from common cfg, we could use it to
notify a specific virt queue.
- device cfg
Where virtio_net_config structure is located.
- isr cfg
Where to read isr (interrupt status).
If any of above cap is not found, we fallback to the legacy virtio
handling.
If succeed, hw->vtpci_ops is assigned to modern_ops, where all
operations are implemented by reading/writing a (or few) specific
configuration space from above 4 cfg structures. And that's basically
how this patch works.
Besides those changes, virtio 1.0 introduces a new status field:
FEATURES_OK, which is set after features negotiation is done.
Last, set the VIRTIO_F_VERSION_1 feature flag.

Introduce struct virtio_pci_ops, to let legacy virtio (v0.95) and

With that, this patch reimplements all exported pci functions, in
a way like:
vtpci_foo_bar(struct virtio_hw *hw)
{
hw->vtpci_ops->foo_bar(hw);
}
So that we need pay attention to those pci related functions only
while adding virtio 1.0 support.
This patch introduced a new vtpci function, vtpci_init(), to do

offset arg of vtpci_read/write_dev_config is derived from offsetof(),
which is of size_t type, instead of uint64_t. So, define it as size_t
type.

The x550 MDIO clock speed must be configured prior to first MDIO read or
write. The default MDIO clock speed is not valid, therefore the driver
is configuring a valid speed prior to reading the copper PHY device id.

This patch removes KR PHY reset from ixgbe_init_phy_ops_X550em. Since
this function is meant to initialize function pointers for detected PHY
type. Internal PHY reset was moved to ixgbe_setup_internal_phy_t_x550em
which will now detect which mode does internal PHY work in, and setup it
as required.

KR auto-neg mode is what we will be using going forward. The SW
interface for this mode is different than what was used for iXFI.
While debugging, it was determined that the ucode diagnostic was
no longer needed. This code has been removed to simplify the init
flow.
A subtle semaphore error in the CS4227 reset flow was fixed.

Avoid a needless PHY access on copper phys to save the 10ms wait
time for each PHY access. A helper function is introduced to
actually do the register access and process the contents.

Waiting for FDIRCMD completion is an expensive thing to do in the
transmit hot path. This wait was added to catch problems with perfect
filter rules, and, at least in the Linux driver, there is no error
check anyway, so there is no point to adding the delay. So do not wait
for completion. Change the return of the function to void, since it has
no meaningful return value.

This patch adds the flow control ethertype to the defines for the
ETQF filter list. This only adds the define. Each driver
can add this ethertype to the filter. This is needed to prevent
denial of service by malicious VFs sending out flow control
packets.

Currently credit_refill and credit_max could be zero for a TC and that
is causing Tx hang for CEE mode configuration, so to fix that have at
min credit assigned to a TC and that is as what IEEE mode already does.

Coverity issue reported like
CID 119268 (#1 of 1): Unintended sign extension
(SIGN_EXTENSION)sign_extension: Suspicious implicit sign extension:
vsi_id with type unsigned short (16 bits, unsigned) is promoted in
vsi_id << 23 to type int (32 bits, signed), then sign-extended to type
unsigned long (64 bits, unsigned). If vsi_id << 23 is greater than
0x7FFFFFFF, the upper bits of the result will all be 1.
