Currently, if there are vlans on top of bond, alb_send_learning_packets()
will never send LPs from the bond itself (i.e. untagged), which might leave
untagged clients unupdated.
Also, the 'circular vlan' logic (i.e. update only MAX_LP_BURST vlans at a
time, and save the last vlan for the next update) is really suboptimal - in
case of lots of vlans it will take a lot of time to update every vlan. It
is also never called in any hot path and sends only a few small packets -
thus the optimization by itself is useless.
So remove the whole current_alb_vlan/MAX_LP_BURST logic from
alb_send_learning_packets(). Instead, we'll first send a packet untagged
and then traverse the upper dev list, sending a tagged packet for each vlan
found. Also, remove the MAX_LP_BURST define - we already don't need it.

Currently, bond_has_this_ip() is aware only of vlan upper devices, and thus

Currently, bond_arp_send_all() is aware only of vlans, which breaks
configurations like bond <- bridge (or any other 'upper' device) with IP
(which is quite a common scenario for virt setups).
To fix this we convert the bond_arp_send_all() to first verify if the rt
device is the bond itself, and if not - to go through its list of upper
vlans and their respectiv upper devices (if the vlan's upper device matches
- tag the packet), if still not found - go through all of our upper list
devices to see if any of them match the route device for the target. If the
match is a vlan device - we also save its vlan_id and tag it in
bond_arp_send().
Also, clean the function a bit to be more readable.

Jeff Kirsher says:
====================
This series contains updates to ixgbe.
Jacob provides a fix for 82599 devices where it can potentially keep link
lights up when the adapter has gone down.
Mark provides a fix to resolve the possible use of uninitialized memory
by checking the return value on EEPROM reads.
Don provides 2 patches, one to fix a issue where we were traversing the
Tx ring with the value of IXGBE_NUM_RX_QUEUES which currently happens
to have the correct value but this is misleading. A change later, could
easily make this no longer correct so when traversing the Tx ring, use
netdev->num_tx_queues. His second patch does some minor clean ups of log
messages.
Emil provides the remaining ixgbe patches. First he fixes the link test
where forcing the laser before the link check can lead to inconsistent
results because it does not guarantee that the link will be negotiated
correctly. Then he initializes the message buffer array to 0 in order
to avoid using random numbers from the memory as a MAC address for the
VF. Emil also fixes the read loop for the I2C data to account for the
offset for SFP+ modules. Lastly, Emil provides several patches to add
support for QSFP modules where 1Gbps support is added as well as support
for older QSFP active direct attach cables which pre-date SFF-8436 v3.6.

This adds support for the EF10 network controller architecture and the
SFC9100 family, starting with SFC9120 'Farmingdale', and bumps the
driver version to 4.0.
New features in the SFC9100 family include:
- Flexible allocation of internal resources to PCIe physical and virtual
functions under firmware control
- RX event merging to reduce DMA writes at high packet rates
- Integrated RX timestamping
- PIO buffers for lower TX latency
- Firmware-driven data path that supports additional offload features
and filter types
- Delivery of packets between functions and to multiple recipients,
allowing firmware to implement a vswitch
- Multiple RX flow hash (RSS) contexts with their own hash keys and
indirection tables
- 40G MAC (single port only)
...not all of which are enabled in this initial driver or the initial

ixgbe: ethtool ixgbe_diag_test cleanup
Specifically forcing the laser before the link check can lead to
inconsistent results because it does not guarantee that the link will be
negotiated correctly. Such is the case when dual speed SFP+ module is
connected to a gigabit link partner.

We were transversing the tx_ring with IXGBE_NUM_RX_QUEUES. Now this define
happens to have the correct value but this is misleading and a change later
could easily make this no longer true. I updated it to netdev->num_tx_queues
like we use in ixgbe_get_strings().

This patch fixes the possible use of uninitialized memory by checking the
return value on eeprom reads. These issues were identified by static
analysis. In many cases error messages will be produced so that corrupted
eeprom issues will be more visible.

This patch fixes an issue with the 82599 adapter where it can potentially keep
link lights up when the adapter has gone down. The patch adds a function which
ensures link is disabled, and calls this function when the adapter transitions
to a down state.

====================
1. Further cleanup and refactoring in preparation for EF10.
2. Remove ethtool stats that are always zero on Falcon boards.
3. Add an ethtool stat for merged TX completions.
4. Prepare to support merged RX completions.
5. Prepare to support more hwmon sensors.
6. Add support for new events that are generated by EF10 firmware.
7. Update MC reboot detection for EF10.

This function checks the upper bound but it doesn't check for negative
numbers:
if (txq > QLCNIC_MAX_TX_RINGS) {
I've solved this by making "txq" a u32 type. I chose that because
->tx_count in the ethtool_channels struct is a __u32.
This bug was added in aa4a1f7df7 ('qlcnic: Enable Tx queue changes using
ethtool for 82xx Series adapter.').

As we move to 1:1 model and melt xen_netbk and xenvif together, it would
be better to use single prefix for all functions in xen-netback.

This patch implements 1:1 model netback. NAPI and kthread are utilized
to do the weight-lifting job:
- NAPI is used for guest side TX (host side RX)
- kthread is used for guest side RX (host side TX)
Xenvif and xen_netbk are made into one structure to reduce code size.
This model provides better scheduling fairness among vifs. It is also
prerequisite for implementing multiqueue for Xen netback.

The data flow from DomU to DomU on the same host in current copying
scheme with tracking facility:
copy
DomU --------> Dom0 DomU
| ^
|____________________________|
copy
The page in Dom0 is a page with valid MFN. So we can always copy from
page Dom0, thus removing the need for a tracking facility.
copy copy
DomU --------> Dom0 -------> DomU
Simple iperf test shows no performance regression (obviously we copy
twice either way):
W/ tracking: ~5.3Gb/s
W/o tracking: ~5.4Gb/s

When trying to debug an interrupt delivery problem I noticed that not
all of the wakeup conditions on the worker thread were included in the
debug message. This patch rectifies that.

AR9462 requires this HW fix for ASPM to work properly.
Also, since WARegVal is used only for the AR8003 family,
use AR_SREV_9300_20_OR_LATER.
