e397286b8e r8169: remove TBI 1000BaseX support
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).

d241d4aac9 net: phy: realtek: add support for RTL8211
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.

49d1751256 r8169: use standard debug output functions
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.

bd43d1ba12 net: mvpp2: prs: Drop unions representing TCAM and SRAM entries
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.

484c016d93 bnx2x: Fix receiving tx-timeout in error or recovery state.
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.

5037c62806 cnic: tidy up a size calculation
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.

Anyway, it's more conventional to use the BITS_TO_LONGS() macro when
we're allocating a bitmap.

83235822b8 nfp: stop limiting VFs to 0
Before 8d85a7a4f2 ("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 8d85a7a4f2, 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 8d85a7a4f2, 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.

Fixes: 8d85a7a4f2 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0")

mlx5e netdevice driver updates:

- Boris Pismenny added the support for UDP GSO in the first two patches.
  Impressive performance numbers are included in the commit message,
  @Line rate with ~half of the cpu utilization compared to non offload
  or no GSO at all.

- 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.

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.

84a0d4669c ath9k: use irqsave() in USB's complete callback
The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

9a98302de1 rtlwifi: rtl8821ae: fix firmware is not ready to run
Without this patch, firmware will not run properly on rtl8821ae, and it
causes bad user experience. For example, bad connection performance with
low rate, higher power consumption, and so on.

rtl8821ae uses two kinds of firmwares for normal and WoWlan cases, and
each firmware has firmware data buffer and size individually. Original
code always overwrite size of normal firmware rtlpriv->rtlhal.fwsize, and
this mismatch causes firmware checksum error, then firmware can't start.

In this situation, driver gives message "Firmware is not ready to run!".

Having a background thread running in the driver all the time is bad for

interval can be done in user space..
