cda2cab077 bnxt_en: Move devlink_register before registering netdev
Latest kernels get the phys_port_name via devlink, if
ndo_get_phys_port_name is not defined. To provide the phys_port_name
correctly, register devlink before registering netdev.

Also call devlink_port_type_eth_set() after registering netdev as
devlink port updates the netdev structure and notifies user.

83d8f5e92d bnxt_en: Improve link up detection.
In bnxt_update_phy_setting(), ethtool_get_link_ksettings() and
bnxt_disable_an_for_lpbk(), we inconsistently use netif_carrier_ok()
to determine link.  Instead, we should use bp->link_info.link_up
which has the true link state.  The netif_carrier state may be off
during self-test and while the device is being reset and may not always
reflect the true link state.

By always using bp->link_info.link_up, the code is now more
consistent and more correct.  Some unnecessary link toggles are
now prevented with this patch.

'alloc_etherdev_mqs()' expects first 'tx', then 'rx'. The semantic here
looks reversed.

Reorder the arguments passed to 'alloc_etherdev_mqs()' in order to keep
the correct semantic.

In fact, this is a no-op because both XGENE_NUM_[RT]X_RING are 8.

b23bfa5633 bpf, xdp: Remove no longer required rcu_read_{un}lock()
Now that we depend on rcu_call() and synchronize_rcu() to also wait
for preempt_disabled region to complete the rcu read critical section
in __dev_map_flush() is no longer required. Except in a few special
cases in drivers that need it for other reasons.

These originally ensured the map reference was safe while a map was
also being free'd. And additionally that bpf program updates via
ndo_bpf did not happen while flush updates were in flight. But flush
by new rules can only be called from preempt-disabled NAPI context.
The synchronize_rcu from the map free path and the rcu_call from the
delete path will ensure the reference there is safe. So lets remove
the rcu_read_lock and rcu_read_unlock pair to avoid any confusion
around how this is being protected.

If the rcu_read_lock was required it would mean errors in the above
logic and the original patch would also be wrong.

Now that we have done above we put the rcu_read_lock in the driver
code where it is needed in a driver dependent way. I think this
helps readability of the code so we know where and why we are
taking read locks. Most drivers will not need rcu_read_locks here
and further XDP drivers already have rcu_read_locks in their code
paths for reading xdp programs on RX side so this makes it symmetric
where we don't have half of rcu critical sections define in driver
and the other half in devmap.

9719c6b98d bpf, xdp: virtio_net use access ptr macro for xdp enable check
virtio_net currently relies on rcu critical section to access the xdp
program in its xdp_xmit handler. However, the pointer to the xdp program
is only used to do a NULL pointer comparison to determine if xdp is
enabled or not.

Use rcu_access_pointer() instead of rcu_dereference() to reflect this.
Then later when we drop rcu_read critical section virtio_net will not
need in special handling.

- kernel is built with CONFIG_NET_SWITCHDEV support

Otherwise adding qtnfmac wireless interfaces into the same bridge
should not be allowed since packets flooded by kernel may break

6b6c150b84 rtw88: use shorter delay time to poll PS state
When TX packet arrives, driver should leave deep PS state to make
sure the DMA is working. After requested to leave deep PS state,
driver needs to poll the PS state to check if the mode has been
changed successfully. The driver used to check the state of the
hardware every 20 msecs, which means upon the first failure of
state check, the CPU is delayed 20 msecs for next check. This is
harmful for some time-sensitive applications such as media players.

So, use shorter delay time each check from 20 msecs to 100 usecs.
The state should be changed in several tries. But we still need
to reserve ~15 msecs in total in case of the state just took too
long to be changed successfully. If the states of driver and the
hardware is not synchronized, the power state could be locked
forever, which mean we could never enter/leave the PS state.

Sometimes the TX queue may be empty and we could possible

then there is nothing to do, just leave the ISR.

And the TX queue should not be empty here, so print an error

8c8e60fb86 brcmfmac: sdio: Fix OOB interrupt initialization on brcm43362
Commit 262f2b53f6 ("brcmfmac: call brcmf_attach() just before calling
brcmf_bus_started()") changed the initialization order of the brcmfmac
SDIO driver. Unfortunately since brcmf_sdiod_intr_register() is now
called before the sdiodev->bus_if initialization, it reads the wrong
chip ID and fails to initialize the GPIO on brcm43362. Thus the chip
cannot send interrupts and fails to probe:

[   12.517023] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
[   12.531214] ieee80211 phy0: brcmf_bus_started: failed: -110
[   12.536976] ieee80211 phy0: brcmf_attach: dongle is not responding: err=-110
[   12.566467] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed

Initialize the bus interface earlier to ensure that
brcmf_sdiod_intr_register() properly sets up the OOB interrupt.

70e5b8f445 mwifiex: drop most magic numbers from mwifiex_process_tdls_action_frame()
Before commit 1e58252e33 ("mwifiex: Fix heap overflow in
mmwifiex_process_tdls_action_frame()"),
mwifiex_process_tdls_action_frame() already had too many magic numbers.
But this commit just added a ton more, in the name of checking for
buffer overflows. That seems like a really bad idea.

Let's make these magic numbers a little less magic, by
(a) factoring out 'pos[1]' as 'ie_len'
(b) using 'sizeof' on the appropriate source or destination fields where
    possible, instead of bare numbers
(c) dropping redundant checks, per below.

Regarding redundant checks: the beginning of the loop has this:

                if (pos + 2 + pos[1] > end)
                        break;

but then individual 'case's include stuff like this:

 			if (pos > end - 3)
 				return;
 			if (pos[1] != 1)
				return;

Note that the second 'return' (validating the length, pos[1]) combined
with the above condition (ensuring 'pos + 2 + length' doesn't exceed
'end'), makes the first 'return' (whose 'if' can be reworded as 'pos >
end - pos[1] - 2') redundant. Rather than unwind the magic numbers
there, just drop those conditions.

7195c8747e ath11k: fix up some error paths
There are two error paths where "ret" wasn't set.  Also one error path
we set the error code to -EINVAL but we should just preserve the error
code from ath11k_hal_srng_get_entrysize().  That function only returns
-EINVAL so this doesn't change anything.

I removed the "ret = 0;" initializers so that hopefully GCC will be able
to detect these sorts of bugs in the future.

====================
100GbE Intel Wired LAN Driver Updates 2020-01-25

This series contains updates to the ice driver to add support for RSS.

Henry and Tony enable the driver to write the filtering hardware tables
to allow for changing of RSS rules, also introduced and initialized the
structures for storing the configuration.  Then followed it up by
creating an extraction sequence based on the packet header protocols to
be programmed.  Next was storing the TCAM entry with the profile data
and VSI group in the respective software structures.

Md Fahad sets up the configuration to support RSS tables for the virtual
function (VF) driver (iavf).  Add support for flow types TCP4, TCP6,
UDP4, UDP6, SCTP4 and SCTP6 for RSS via ethtool.

a1769bb68a Revert "ath10k: fix DMA related firmware crashes on multiple devices"
This reverts commit 76d164f582.
PCIe hung issue was observed on multiple platforms. The issue was reproduced
when DUT was configured as AP and associated with 50+ STAs.

For QCA9984/QCA9888, the DMA_BURST_SIZE register controls the AXI burst size
of the RD/WR access to the HOST MEM.
0 - No split , RAW read/write transfer size from MAC is put out on bus
    as burst length
1 - Split at 256 byte boundary
2,3 - Reserved

With PCIe protocol analyzer, we can see DMA Read crossing 4KB boundary when
issue happened. It broke PCIe spec and caused PCIe stuck. So revert
the default value from 0 to 1.

Tested:  IPQ8064 + QCA9984 with firmware 10.4-3.10-00047
         QCS404 + QCA9984 with firmware 10.4-3.9.0.2--00044

The simulate fail of sdio is not a real sdio transter fail, it only
set an error status in mmc_should_fail_request after the transfer end,
actually the transfer is success, then sdio_io_rw_ext_helper will
return error status and stop transfer the left data. For example,
the really RX len is 286 bytes, then it will split to 2 blocks in
sdio_io_rw_ext_helper, one is 256 bytes, left is 30 bytes, if the
first 256 bytes get an error status by mmc_should_fail_request,then
the left 30 bytes will not read in this RX operation. Then when the
next RX arrive, the left 30 bytes will be considered as the header
of the read, the top 8 bytes will be considered as ath10k_htc_hdr,
but actually the 8 bytes is not the ath10k_htc_hdr, so the act_len
from this ath10k_htc_hdr is not correct, if it is a big value, such
as 57013, it will trigger skb_panic.

Drop the skb with invalid length will be reasonable.

This patch only effect sdio chips.
