d76f8513fa rsi: reset hibernate_resume flag to work hibernate resume in coex mode.
In coex mode, observed hibernate resume is not working properly, as the
hibernate_resume flag is not getting reset in rsi_coex_recv_pkt(),
when common card ready indication received from firmware. Hence resetting
hibernate_resume flag in this function.

54b5172087 rsi: Add null check for virtual interfaces in wowlan config
When the "poweroff" command is executed after wowlan enabled, we have
observed a system crash. In the system "poweroff" sequence, network-manager
is sent to inactive state by cleaning up the network interfaces, using
rsi_mac80211_remove_interface() and when driver tries to access those
network interfaces in rsi_wowlan_config() which was invoked by SDIO
shutdown, results in a crash. Added a NULL check before accessing the
network interfaces in rsi_wowlan_config().

1204aa17f3 brcmfmac: set WIPHY_FLAG_HAVE_AP_SME flag
brcmfmac is a FullMAC driver and it implements/uses cfg80211 interface
for stations management. At the same time it doesn't receive or pass up
management frames.

This flag indicates that authenticator doesn't have to subscribe to or
handle management frames. Some authenticators (e.g. hostapd) were
working with brcmfmac thanks to some extra assumptions. This commit
clears up the situation.

9bf5085aaa net: stmmac: dwmac-sun8i: Add support for GMAC on Allwinner R40 SoC
The Allwinner R40 SoC has the EMAC controller supported by dwmac-sun8i.
It is named "GMAC", while EMAC refers to the 10/100 Mbps Ethernet
controller supported by sun4i-emac. The controller is the same, but
the R40 has the glue layer controls in the clock control unit (CCU),
with a reduced RX delay chain, and no TX delay chain.

This patch adds support for it using the framework laid out by previous
patches to map the differences.

49a06cae6e net: stmmac: dwmac-sun8i: Allow getting syscon regmap from external device
On the Allwinner R40 SoC, the "GMAC clock" register is in the CCU
address space. Using a standard syscon to access it provides no
coordination with the CCU driver for register access. Neither does
it prevent this and other drivers from accessing other, maybe critical,
clock control registers. On other SoCs, the register is in the "system
control" address space, which might also contain controls for mapping
SRAM to devices or the CPU. This hardware has the same issues.

Instead, for these types of setups, we let the device containing the
control register create a regmap tied to it. We can then get the device
from the existing syscon phandle, and retrieve the regmap with
dev_get_regmap().

25ae15fb0e net: stmmac: dwmac-sun8i: Use regmap_field for syscon register access
On the Allwinner R40, the "GMAC clock" register is located in the CCU
block, at a different register address than the other SoCs that have
it in the "system control" block.

This patch converts the use of regmap to regmap_field for mapping and
accessing the syscon register, so we can have the register address in
the variants data, and not in the actual register manipulation code.

This patch only converts regmap_read() and regmap_write() calls to
regmap_field_read() and regmap_field_write() calls. There are some
places where it might make sense to switch to regmap_field_update_bits(),
but this is not done here to keep the patch simple.

b196d88aba tun: fix use after free for ptr_ring
We used to initialize ptr_ring during TUNSETIFF, this is because its
size depends on the tx_queue_len of netdevice. And we try to clean it
up when socket were detached from netdevice. A race were spotted when
trying to do uninit during a read which will lead a use after free for
pointer ring. Solving this by always initialize a zero size ptr_ring
in open() and do resizing during TUNSETIFF, and then we can safely do
cleanup during close(). With this, there's no need for the workaround
that was introduced by commit 4df0bfc799 ("tun: fix a memory leak

This series contains updates to virtchnl, i40e and i40evf.

Bruce cleans up whitespace and unnecessary parentheses in virtchnl.

Jake does a number of stat cleanups in the i40e driver, including
cleanup of code indentation, whitespace issues, remove duplicate stats,
fix grammar in code comment and general spring cleaning of the
statistics code.

Patryk fixes an issue where we recalculate vectors left and vectors
wanted but do not take into account the reduced number of queue pairs
per VSI.

Harshitha adds tx_busy stat to ethtool stats to track the number of
times we return NETDEV_TX_BUSY to the stack during transmit.

Paweł fixes a potential system crash when unloading the VF driver after
a hardware reset.

c79756cb5f i40e: free the skb after clearing the bitlock
In commit bbc4e7d273 ("i40e: fix race condition with PTP_TX_IN_PROGRESS
bits") we modified the code which handles Tx timestamps so that we would
clear the progress bit as soon as possible.

A later commit 0bc0706b46 ("i40e: check for Tx timestamp timeouts during
watchdog") introduced similar code for detecting and handling cleanup of
a blocked Tx timestamp. This code did not use the same pattern for cleaning
up the skb.

Update this code to wait to free the skb until after the bit lock is
free, by first setting the ptp_tx_skb to NULL and clearing the lock.

aa4a065403 i40evf: remove MAX_QUEUES and just use I40EVF_MAX_REQ_QUEUES
We don't really need to have separate definitions for MAX_QUEUES and
I40EVF_MAX_REQ_QUEUES, since we'll always be limited by how many queues
we request anyways. If we haven't enabled requesting the maximum number
of queues, there's no reason to have our call to alloc_etherdev_mq
actually pass the higher value, since we'd never enable those queues
anyways.

3f76d01f3e i40e: add tx_busy to ethtool stats
This patch adds the tx_busy stat to the ethtool stats. The tx_busy
stat tracks the number of times we return NETDEV_TX_BUSY to the stack
during transmit.

ca12c9d421 i40e: Fix recalculation of MSI-X vectors for VMDq
This patch adds a recalculation of number of MSI-X
vectors for VMDq in the case where we have less
vectors available than we would want to reserve for
VMDq.

It fixes the issue where we recalculate vectors left
and vectors wanted but we didn't take into account
the reduced number of queue pairs per VSI.

To keep the patches easy to review, cleanup some of the indentation used

7e20188176 i40e: remove duplicate pfc stats
The pfc related priority stats are already handled separately as these
stats are actually arrays of length I40E_MAX_USER_PRIORITY. Thus,
including them within i40e_gstrings_stats will just duplicate data.

Worse, the sizeof will be incorrect, as it will be the total size of the
stat arrays, which in this case is 8 * sizeof(u64), so we will only copy
the stat contents as if they were a u32.

Since we already correctly handle these stats else where, remove them
from the i40e_gstrings_stats.
