There exists a set of Bluetooth USB devices that show up on the USB
bus as 0a12:0001 and identify themselves as devices from CSR. However
they are not. When sending Read Local Version command they now have
a split personality and say they are from Broadcom.
< HCI Command: Read Local Version Information (0x04|0x0001) plen 0
> HCI Event: Command Complete (0x0e) plen 12
Read Local Version Information (0x04|0x0001) ncmd 1
status 0x00
HCI Version: 2.0 (0x3) HCI Revision: 0x3000
LMP Version: 2.0 (0x3) LMP Subversion: 0x420b
Manufacturer: Broadcom Corporation (15)
The assumption is that they are neither CSR nor Broadcom based devices
and that they are designed and manufactured by someone else.
For the most parts they follow the Bluetooth HCI specification and
can be used as standard Bluetooth devices. However they have the
minor problem that the Delete Stored Link Key command is not working
as it should.
During the Bluetooth controller setup, this command is needed if
stored link keys are supported. For these devices it has to be
assumed that this is broken and so just set a quirk to clearly
indicate the behavior. After that the setup can just proceed.
Now the trick part is to detect these faulty devices since we do
not want to punish all CSR and all Broadcom devices. The original
devices do actually work according to the specification.
What is known so far is that these broken devices set the USB bcdDevice
revision information to 1.0 or less.
T: Bus=02 Lev=01 Prnt=01 Port=08 Cnt=03 Dev#= 9 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs= 1
P: Vendor=0a12 ProdID=0001 Rev= 1.00
S: Manufacturer=Bluetooth v2.0
S: Product=Bluetooth V2.0 Dongle
T: Bus=05 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs= 1
P: Vendor=0a12 ProdID=0001 Rev= 0.07
In case of CSR devices, the bcdDevice revision contains the firmware
build ID and that is normally a higher value. If the bcdDevice revision
is 1.0 or less, then an extra setup stage is checking if Read Local
Version returns CSR manufacturer information. If not then it will be
assumed that this is a broken device and the Delete Stored Link Key
command will be marked as broken.

Some controller pretend they support the Delete Stored Link Key command,
but in reality they really don't support it.
< HCI Command: Delete Stored Link Key (0x03|0x0012) plen 7
bdaddr 00:00:00:00:00:00 all 1
> HCI Event: Command Complete (0x0e) plen 4
Delete Stored Link Key (0x03|0x0012) ncmd 1
status 0x11 deleted 0
Error: Unsupported Feature or Parameter Value
Not correctly supporting this command causes the controller setup to
fail and will make a device not work. However sending the command for
controller that handle stored link keys is important. This quirk
allows a driver to disable the command if it knows that this command
handling is broken.

Fix the VF reset flow so that it works on real hardware. After

- Change the i40e_reset_vf function to a void type, and fix
up the callers to reflect this.
- Move the MSI-X disable code to i40e_free_vf_res since it must
be done every time the VF is freed, regardless of whether or
not it is reset.
- Ensure that the PCIe bus is quiet before polling the reset bit.
- Don't clear the VFGEN_RSTAT1 register at the beginning as it is
cleared by the reset.
- Poll longer for the reset to be done.
- Disable the queues using an existing function rather than
rolling our own.
- Free and reallocate the VSI after reset to avoid rx hang.

SE discovery errors are currently overwriting the dev_up() return error.
This is wrong for many reasons:
- We don't want to report an error if we actually brought the device up
but it failed to discover SEs. By doing so we pretend we don't have an
NFC functional device even we do. The only thing we could not do was
checking for SEs availability. This is the false negative case.
- In some cases the actual device power up failed but the SE discovery
succeeded. Userspace then believes the device is up while it's not.
This is the false positive case.

bonding: final set of netlink patches
v2:
- per Jiri's comment, fix ad_select checking against parm table by
spliting bond_parse_parm() into several funcs. Go ahead and apply
same technique to all parameters using parm table.
- fix netlink msg size to including missing nest attr
- drop the last patch for active_slaves. This patch needs to be
reworked per Jiri's comments and shouldn't hold up finalizing
the conversion of the existing parameter to netlink attributes.
Ding, assuming this patch set goes in, you should have all you
need to start converting module parameter setting/checking over to
funcs in *_options.c.
I'll send iproute2 patch for bonding netlink support once this patch
set is accepted.
v1:
The following series implements the last set of bonding netlink attributes
for 802.3ad mode:
lacp_rate
ad_select
ad_info, nest of:
ad_aggregator
ad_num_ports
ad_actor_key
ad_partner_key
ad_partner_mac
The last patch adds an additional netlink attribute, active_slaves, which
is a nested list of ifindices for current active slaves. We're using this
list to enable/disable hashing of ports in a hardware LAG implementation.
In the same way bonding driver includes/excludes ports for 802.3ad egress
hashing, hardware ports are included/excluded from egress hashing by
hardware based on port active status. Yes, data path offloaded to
hardware, control path remains in kernel via bonding driver.

On ASF enabled devices where the mgmt firmware runs on the application
