====================
wireless-drivers-next patches for v5.10
First set of patches for v5.10. Most noteworthy here is ath11k getting
initial support for QCA6390 and IPQ6018 devices. But most of the
patches are cleanup: W=1 warning fixes, fallthrough keywords, DMA API
changes and tasklet API changes.
Major changes:
ath10k
* support SDIO firmware codedumps
* support station specific TID configurations
ath11k
* add support for IPQ6018
* add support for QCA6390 PCI devices
ath9k
* add support for NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to improve PTK0
rekeying
wcn36xx
* add support for TX ack

ath.git patches for v5.10. Major changes:

* support SDIO firmware codedumps
* support station specific TID configurations
ath11k
* add support for IPQ6018
Drop some bogus Kconfig selects that are not entirely accurate, and
unnecessary to begin with, since the same Kconfig options also select
LIB80211 features that already imply the selected functionality (AES
for CCMP, ARC4 and ECB for TKIP)

In the functions mvpp2_isr_handle_xlg() and
mvpp2_isr_handle_gmac_internal(), the bool variable link is assigned a
true value in the case that a given bit of val is set. However, if the
bit is unset, no value is assigned to link and it is then passed to
mvpp2_isr_handle_link() without being initialised. Fix by assigning to
link the value of the bit test.

We allow drivers to call napi_hash_del() before calling
netif_napi_del() to batch RCU grace periods. This makes
the API asymmetric and leaks internal implementation details.
Soon we will want the grace period to protect more than just
the NAPI hash table.
Restructure the API and have drivers call a new function -
__netif_napi_del() if they want to take care of RCU waits.
Note that only core was checking the return status from
napi_hash_del() so the new helper does not report if the
NAPI was actually deleted.
Some notes on driver oddness:
- veth observed the grace period before calling netif_napi_del()
but that should not matter
- myri10ge observed normal RCU flavor
- bnx2x and enic did not actually observe the grace period
(unless they did so implicitly)
- virtio_net and enic only unhashed Rx NAPIs
The last two points seem to indicate that the calls to
napi_hash_del() were a left over rather than an optimization.
Regardless, it's easy enough to correct them.
This patch may introduce extra synchronize_net() calls for
interfaces which set NAPI_STATE_NO_BUSY_POLL and depend on
free_netdev() to call netif_napi_del(). This seems inevitable
since we want to use RCU for netpoll dev->napi_list traversal,
and almost no drivers set IFF_DISABLE_NETPOLL.

There are a couple bugs here:
1) If opt[1] is zero then this results in a forever loop. If the value
is less than 2 then it is invalid.
2) It assumes that "len" is more than sizeof(valid_accm) or 6 which can
result in memory corruption.
In the case of LCP_OPTION_ACCM, then we should check "opt[1]" instead
of "len" because, if "opt[1]" is less than sizeof(valid_accm) then
"nak_len" gets out of sync and it can lead to memory corruption in the
next iterations through the loop. In case of LCP_OPTION_MAGIC, the
only valid value for opt[1] is 6, but the code is trying to log invalid
data so we should only discard the data when "len" is less than 6
because that leads to a read overflow.

Since the micrel phy driver calls phy_init_hw() as a workaround,
the commit 9886a4dbd2 ("net: phy: call phy_disable_interrupts()
in phy_init_hw()") disables the interrupt unexpectedly. So,
call phy_disable_interrupts() in phy_attach_direct() instead.
Otherwise, the phy cannot link up after the ethernet cable was
disconnected.
Note that other drivers (like at803x.c) also calls phy_init_hw().
So, perhaps, the driver caused a similar issue too.

Even tho mlx4_core registers the devlink ports, it's mlx4_en
and mlx4_ib which set their type. In situations where one of
the two is not built yet the machine has ports of given type
we see the devlink warning from devlink_port_type_warn() trigger.
Having ports of a type not supported by the kernel may seem
surprising, but it does occur in practice - when the unsupported
port is not plugged in to a switch anyway users are more than happy
not to see it (and potentially allocate any resources to it).
Set the type in mlx4_core if type-specific driver is not built.

The for loop in i40e_set_vsi_promisc() reports errors via dev_err() but
does not propagate the error up the call chain. Instead it continues the
loop and potentially overwrites the reported error value.
This results in the error being recorded in the log buffer, but the
caller might never know anything went the wrong way.
To avoid this situation i40e_set_vsi_promisc() needs to temporarily store
the error after reporting it. This is still not optimal as multiple
different errors may occur, so store the first error and hope that's
the main issue.
