Small merge conflict in net/mac80211/scan.c, I preserved
the kcalloc() conversion. -DaveM
Johannes Berg says:
====================
This round's updates:
* finally some of the promised HE code, but it turns
out to be small - but everything kept changing, so
one part I did in the driver was >30 patches for
what was ultimately <200 lines of code ... similar
here for this code.
* improved scan privacy support - can now specify scan
flags for randomizing the sequence number as well as
reducing the probe request element content
* rfkill cleanups
* a timekeeping cleanup from Arnd
* various other cleanups

The very first version of RTL8169 from 2002 (and only this one) has
support for a TBI 1000BaseX fiber interface. The TBI support in the
driver makes switching to phylib tricky, so best would be to get
rid of it. I found no report from anybody using a device with RTL8169
and fiber interface, also the vendor driver doesn't support this mode
(any longer).
So remove TBI support and bail out with a message if a card with
activated TBI is detected. If there really should be any user of it
out there, we could add a stripped-down version of the driver
supporting chip version 01 and TBI only (and maybe move it to
staging).

In preparation of adding phylib support to the r8169 driver we need
PHY drivers for all chip-internal PHY types. Fortunately almost all
of them are either supported by the Realtek PHY driver already or work
with the genphy driver.
Still missing is support for the PHY of RTL8169s, it requires a quirk
to properly support 100Mbit-fixed mode. The quirk was copied from
r8169 driver which copied it from the vendor driver.
Based on the PHYID the internal PHY seems to be a RTL8211.

I see no need to define a private debug output symbol, let's use the
standard debug output functions instead. In this context also remove
the deprecated PFX define.
The one assertion is wrong IMO anyway, this code path is used also
by chip version 01.

PPv2's Header Parser use some large TCAM and SRAM entries, that are
duplicated in software so that we can write them to hardware only when
we are done modifying them.
Currently, PPv2 uses a union containing arrays of u32 and u8 to represent
these entries, to facilitate byte per byte access. This representation is
broken when we want to support big endian, and this makes the code
confusing to read.
This patch drops the union, and simply stores the TCAM and SRAM entries
as u32 arrays, each entry corresponding to a 32-bit register.

Driver performs the internal reload when it receives tx-timeout event from
the OS. Internal reload might fail in some scenarios e.g., fatal HW issues.
In such cases OS still see the link, which would result in undesirable
functionalities such as re-generation of tx-timeouts.
The patch addresses this issue by indicating the link-down to OS when
tx-timeout is detected, and keeping the link in down state till the
internal reload is successful.
Please consider applying it to 'net' branch.

Static checkers complain that id_tbl->table points to longs and 4 bytes
is smaller than sizeof(long). But the since other side is dividing by
32 instead of sizeof(long), that means the current code works fine.

Before 8d85a7a4f2c9 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0"),
pci_sriov_set_totalvfs(pdev, 0) meant "we can enable TotalVFs virtual
functions". After 8d85a7a4f2c9, it means "we can't enable *any* VFs".
That broke this scenario where nfp intends to remove any limit on the
number of VFs that can be enabled:
nfp_pci_probe
nfp_pcie_sriov_read_nfd_limit
nfp_rtsym_read_le("nfd_vf_cfg_max_vfs", &err)
pci_sriov_set_totalvfs(pf->pdev, 0) # if FW didn't expose a limit
...
# userspace writes N to sysfs "sriov_numvfs":
sriov_numvfs_store
pci_sriov_get_totalvfs # now returns 0
return -ERANGE
Prior to 8d85a7a4f2c9, pci_sriov_get_totalvfs() returned TotalVFs, but it
now returns 0.
Remove the pci_sriov_set_totalvfs(pdev, 0) calls so we don't limit the
number of VFs that can be enabled.

The TotalVFs register in the SR-IOV capability is the hardware limit on the
number of VFs. A PF driver can limit the number of VFs further with
pci_sriov_set_totalvfs(). When the PF driver is removed, reset any VF
limit that was imposed by the driver because that limit may not apply to
other drivers.
Before 8d85a7a4f2c9 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0"),
pci_sriov_set_totalvfs(pdev, 0) meant "we can enable TotalVFs virtual
functions", and the nfp driver used that to remove the VF limit when the
driver unloads.
8d85a7a4f2c9 broke that because instead of removing the VF limit,
pci_sriov_set_totalvfs(pdev, 0) actually sets the limit to zero, and that
limit persists even if another driver is loaded.
We could fix that by making the nfp driver reset the limit when it unloads,
but it seems more robust to do it in the PCI core instead of relying on the
driver.
The regression scenario is:
nfp_pci_probe (driver 1)
...
nfp_pci_remove
pci_sriov_set_totalvfs(pf->pdev, 0) # limits VFs to 0
...
nfp_pci_probe (driver 2)
nfp_rtsym_read_le("nfd_vf_cfg_max_vfs")
# no VF limit from firmware
Now driver 2 is broken because the VF limit is still 0 from driver 1.

- From Tariq Toukan:
- Convert large order kzalloc allocations to kvzalloc.
- Added performance diagnostic statistics to several places in data path.
From Saeed and Eran,
- Update NIC HW stats on demand only, this is to eliminate the background
thread needed to update some HW statistics in the driver cache in
order to report error and drop counters from HW in ndo_get_stats.

Add constants and callback functions for the dwmac on px30 Soc.
The base structure is the same, but registers and the bits in
them are moved slightly, and add the clk_mac_speed for selecting
mac speed.

In case of WEP encryption, driver has to configure shared key for
associated station(s). Note that sta pointer is NULL in case of non
pairwise key, causing NULL pointer dereference with existing code
(sta_priv->is_data_encrypted). Fix this by using associated sta list
instead. This enables WEP support as client, WEP AP is non-functional.

The trace points to a corrupt skb inside kfree_skb(), seemingly because
one of the shared skb queues is getting corrupted. Most of the skb queues
ath10k uses are local to a single call stack, but three are shared among
multiple codepaths:
- rx_msdus_q,
- rx_in_ord_compl_q, and
- tx_fetch_ind_q
Of the three, the first two are manipulated using the unlocked skb_queue
functions without any additional lock protecting them. Use the locked
variants of skb_queue_* functions to protect these manipulations.
