If the driver receives a TX CQE with status as 0x1 or 0x9 or 0xb,
the completion indexes should not be used. The driver must stop
consuming CQEs from this TXQ/CQ. The TXQ from this point on-wards
to be in a bad state. Driver should destroy and recreate the TXQ.
0x1: LANCER_TX_COMP_LSO_ERR
0x9 LANCER_TX_COMP_SGE_ERR
0xb: LANCER_TX_COMP_PARITY_ERR
Reset the adapter if driver sees this error in TX completion. Also
adding sge error counter in ethtool stats.

The commit 622190669403 ("be2net: Request RSS capability of Rx interface
depending on number of Rx rings") modified be_update_queues() so the
IFACE (HW representation of the netdevice) is destroyed and then
re-created. This causes a regression because potential promiscuous mode
is not restored properly during be_open() because the driver thinks
that the HW has promiscuous mode already enabled.
Note that Lancer is not affected by this bug because RX-filter flags are
disabled during be_close() for this chipset.

to READ_ONCE()/WRITE_ONCE()
Please do not apply this to mainline directly, instead please re-run the
coccinelle script shown below and apply its output.
For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't harmful, and changing them results in
churn.
However, for some features, the read/write distinction is critical to
correct operation. To distinguish these cases, separate read/write
accessors must be used. This patch migrates (most) remaining
ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following
coccinelle script:
----
// Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and
// WRITE_ONCE()
// $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch

On certain platforms BE3 chips may indicate spurious UEs (unrecoverable
error). Because of the UE detection logic was disabled in the driver
for BE3 chips. Because of this, even in cases of a real UE,
a failover will not occur. This patch re-enables UE detection on BE3
and if a UE is detected, reads the POST register. If the POST register,
reports either a FAT_LOG_STATE or a ARMFW_UE, then it means that a valid
UE occurred in the chip.

We disable VxLAN offload when more than 1 UDP port is added to the driver,
since Skyhawk doesn't support offload with multiple ports. The existing
driver design expects the user to delete all port configurations and create
a configuration with a single UDP port for VxLAN offload to be re-enabled.
Remove this restriction by tracking the ports added and re-enabling offload
when ports get deleted and only 1 port is left.

Recent commit 34393529163a ("be2net: fix MAC addr setting on privileged
BE3 VFs") allows privileged BE3 VFs to set its MAC address during
initialization. Although the initial MAC for such VFs is already
programmed by parent PF the subsequent setting performed by VF is OK,
but in certain cases (after fresh boot) this command in VF can fail.
The MAC should be initialized only when:
1) no MAC is programmed (always except BE3 VFs during first init)
2) programmed MAC is different from requested (e.g. MAC is set when
interface is down). In this case the initial MAC programmed by PF
needs to be deleted.
The adapter->dev_mac contains MAC address currently programmed in HW so
it should be zeroed when the MAC is deleted from HW and should not be
filled when MAC is set when interface is down in be_mac_addr_set() as
no programming is performed in this case.
Example of failure without the fix (immediately after fresh boot):
# ip link set eth0 up <- eth0 is BE3 PF
be2net 0000:01:00.0 eth0: Link is Up
# echo 1 > /sys/class/net/eth0/device/sriov_numvfs <- Create 1 VF
...
be2net 0000:01:04.0: Emulex OneConnect(be3): VF port 0
# ip link set eth8 up <- eth8 is created privileged VF
be2net 0000:01:04.0: opcode 59-1 failed:status 1-76
RTNETLINK answers: Input/output error
# echo 0 > /sys/class/net/eth0/device/sriov_numvfs <- Delete VF
iommu: Removing device 0000:01:04.0 from group 33
...
# echo 1 > /sys/class/net/eth0/device/sriov_numvfs <- Create it again
iommu: Removing device 0000:01:04.0 from group 33
...
# ip link set eth8 up

During interface opening MAC address stored in netdev->dev_addr is
programmed in the HW with exception of BE3 VFs where the initial
MAC is programmed by parent PF. This is OK when MAC address is not
changed when an interfaces is down. In this case the requested MAC is
stored to netdev->dev_addr and later is stored into HW during opening.
But this is not done for all BE3 VFs so the NIC HW does not know
anything about this change and all traffic is filtered.
This is the case of bonding if fail_over_mac == 0 where the MACs of
the slaves are changed while they are down.
The be2net behavior is too restrictive because if a BE3 VF has
the FILTMGMT privilege then it is able to modify its MAC without
any restriction.
To solve the described problem the driver should take care about these
privileged BE3 VFs so the MAC is programmed during opening. And by
contrast unpriviled BE3 VFs should not be allowed to change its MAC
in any case.

The adapter->pmac_id[0] item is used for primary MAC address but
this is not true for adapter->uc_list[0] as is assumed in
be_set_uc_list(). There are N UC addresses copied first from net_device
to adapter->uc_list[1..N] and then N UC addresses from
adapter->uc_list[0..N-1] are sent to HW. So the last UC address is never
stored into HW and address 00:00:00:00;00:00 (from uc_list[0]) is used
instead.

Commit 988d44b "be2net: Avoid redundant addition of mac address in HW"
introduced be_dev_mac_add & be_uc_mac_add helpers that incorrectly

be_eth_addr. Consequently NIC is not filled with valid data so unicast

When VXLAN offloading is enabled, be_features_check() tries to check if
an encapsulated packet is indeed a VXLAN packet. The check is not strict
enough, and considers any UDP-encapsulated ethernet frame with a 8-byte
tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE
have a 8-byte header, so they get through this check.
Force the UDP destination port to be the one that has been offloaded to
hardware.
Without this, GENEVE-encapsulated packets can end up having an incorrect
checksum when both a GENEVE and a VXLAN (offloaded) tunnel are
configured.
This is similar to commit a547224dceed ("mlx4e: Do not attempt to
offload VXLAN ports that are unrecognized").

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.
That driver has a change_mtu method explicitly for sending
a message to the hardware. If that fails it returns an
error.
Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.
However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Somehow, I missed a healthy number of ethernet drivers in the last pass.
Most of these drivers either were in need of an updated max_mtu to make
jumbo frames possible to enable again. In a few cases, also setting a
different min_mtu to match previous lower bounds. There are also a few
drivers that had no upper bounds checking, so they're getting a brand new

drivers/net/ethernet/emulex/benet/be_main.c:47:25: warning:
symbol 'be_err_recovery_workq' was not declared. Should it be static?
drivers/net/ethernet/emulex/benet/be_main.c:63:25: warning:
symbol 'be_wq' was not declared. Should it be static?

Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
the ability for user-space application to specify it for the VF, as an
option to support 802.1ad.
We adjusted IP Link tool to support this option.
For future use cases, the new UAPI supports multiple vlans. For now we
limit the list size to a single vlan in kernel.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.
Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol.
Suitable ip link tool command examples:
Set vf vlan protocol 802.1ad:
ip link set eth0 vf 1 vlan 100 proto 802.1ad
Set vf to VST (802.1Q) mode:
ip link set eth0 vf 1 vlan 100 proto 802.1Q
Or by omitting the new parameter
ip link set eth0 vf 1 vlan 100

We get 4 warnings when building kernel with W=1:
drivers/net/ethernet/emulex/benet/be_main.c:4368:6: warning: no previous prototype for 'be_calculate_pf_pool_rss_tables' [-Wmissing-prototypes]
drivers/net/ethernet/emulex/benet/be_cmds.c:4385:5: warning: no previous prototype for 'be_get_nic_pf_num_list' [-Wmissing-prototypes]
drivers/net/ethernet/emulex/benet/be_cmds.c:4537:6: warning: no previous prototype for 'be_reset_nic_desc' [-Wmissing-prototypes]
drivers/net/ethernet/emulex/benet/be_cmds.c:4910:5: warning: no previous prototype for '__be_cmd_set_logical_link_config' [-Wmissing-prototypes]
In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.

If the device mac address is updated using ndo_set_mac_address(),
while the same mac address is already programmed, the driver does not
detect this condition if its netdev->dev_addr has been changed. The
driver tries to add the same mac address resulting in mac address
collision error. This has been observed in bonding mode-5 configuration.
To fix this, store the mac address configured in HW in the adapter
structure. Use this to compare against the new address being updated
to avoid collision.

If a mac address is added to the uc_list and later the same mac address
is added via ndo_set_mac_address() or vice versa, the driver does not
detect this condition and tries to add it again. This results in a mac
address collision error when the FW rejects it.
Fix this by checking if the given mac address is present in uc_list while
setting the device mac address and vice versa. Similarly skip deletion if
the address is still in use in the other form.

SLI cmd.
Driver issues OPCODE_COMMON_GET_EXT_FAT_CAPABILITIES cmd during init which
when issued by VFs results in the logging of a cmd failure message since
they don't have the required privilege for this cmd. Fix by checking
privilege before issuing the cmd.
Also fixed typo in CAPABILITIES.
