wil6210: reset buff id in status message after completion
Since DR bit and buffer id are written in different dwords of
the status message, the DR bit can already be set to 1 while the
buffer id is not updated yet.
Resetting the buffer id in the status message will allow the driver
to identify such cases and re-read the status message until the buffer
id is written by HW.
In case DR bit is set but buffer id is zero, need to read the status
message again, until a valid id is identified.
In addition to that, move the completed buffer id to the tail of the
free list to prevent its immediate reuse in the upcoming refill.

peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats,

ath10k: fix descriptor size in ce tx completion for WCN3990
When the driver receives the tx completion of the
descriptor over ce, it clears the nbytes configured
for that particular descriptor. WCN3990 uses ce
descriptors with 64-bit address.
Currently during handling the tx completion of the
descriptors, the nbytes are accessed from the descriptors
using ce_desc for 32-bit targets. This will lead to clearing
of memory at incorrect offset if DMA MASK is set to greater
than 32 bits.
Attach different ce tx copy completed handler for targets
using address above 32-bit address.

tls: Return type of non-data records retrieved using MSG_PEEK in recvmsg
The patch enables returning 'type' in msghdr for records that are
retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked
from socket from getting clubbed with any other record of different
type when records are subsequently dequeued from strparser.
For each record, we now retain its type in sk_buff's control buffer
cb[]. Inside control buffer, record's full length and offset are already
stored by strparser in 'struct strp_msg'. We store record type after
'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is
stored just after record dequeue. For tls1.3, the type is stored after
record has been decrypted.
Inside process_rx_list(), before processing a non-data record, we check
that we must be able to return back the record type to the user
application. If not, the decrypted records in tls context's rx_list is
left there without consuming any data.

During region rehash, a new region is created with a more optimized set
of masks (ERPs). When transitioning to the new region, all the rules
from the old region are copied one-by-one to the new region. This
transition can be time consuming and currently done under RTNL lock.
In order to remove RTNL lock dependency during region rehash, introduce
multiple smaller locks guarding dedicated structures or parts of them.

====================
net: dsa: microchip: add MIB counters support
This series of patches is to modify the KSZ9477 DSA driver to read MIB
counters periodically to avoid overflow.
The MIB counters should be read only when there is link. Otherwise it is
a waste of time as hardware never increases the counters.
Functions are added to check the port link status so that MIB counters
read call is used efficiently.
v4
- Use readx_poll_timeout
- Fix using mutex in a timer callback function problem
- use dp->slave directly instead of checking whether it is valid
- Add port_cleanup function in a separate patch
- Add a mutex so that changing device variables is safe
v3
- Use netif_carrier_ok instead of checking the phy device pointer
v2
- Create macro similar to readx_poll_timeout to use with switch
- Create ksz_port_cleanup function so that variables like on_ports and
live_ports can be updated inside it
v1
- Use readx_poll_timeout
- Do not clear MIB counters when port is enabled
- Do not advertise 1000 half-duplex mode when port is enabled
- Do not use freeze function as MIB counters may miss counts

Maxime Chevallier says:
====================
net: phy: marvell10g: Add 2.5GBaseT support
This series adds the missing bits necessary to fully support 2.5GBaseT
in the Marvell Alaska PHYs.
The main points for that support are :
- Making use of the .get_features call, recently introduced by Heiner
and Andrew, that allows having a fully populated list of supported
modes, including 2500BaseT.
- Configuring the MII to 2500BaseX when establishing a link at 2.5G
- Adding a small quirk to take into account the fact that some PHYs in
the family won't report the correct supported abilities
The rest of the series consists of small cosmetic improvements such as
using the correct helper to set a linkmode bit and adding macros for the
PHY ids.
We also add support for the
88E2110 PHY, which doesn't require the
quirk, and support for 2500BaseT in the PPv2 driver, in order to have a
fully working setup on the MacchiatoBin board.

The current code reports a link as up if all devices (except a few
blacklisted ones) report the link as up. This breaks Aquantia AQCS109
for lower speeds because on this PHY the PCS link status reflects a
10G link only. For Marvell there's a similar issue, therefore PHYXS
device isn't checked.
There may be more PHYs where depending on the mode the link status
of only selected devices is relevant.
For now it seems to be sufficient to check the link status of the
PMAPMD device only. Leave the loop in the code to be prepared in
case we have to add functionality to check more than one device,
depending on the mode.
Successfully tested on a board with an AQCS109.
