mwifiex: correct channel stat buffer overflows
mwifiex records information about various channels as it receives scan
information. It does this by appending to a buffer that was sized
to the max number of supported channels on any band, but there are
numerous problems:
(a) scans can return info from more than one band (e.g., both 2.4 and 5
GHz), so the determined "max" is not large enough
(b) some firmware appears to return multiple results for a given
channel, so the max *really* isn't large enough
(c) there is no bounds checking when stashing these stats, so problems
(a) and (b) can easily lead to buffer overflows
Let's patch this by setting a slightly-more-correct max (that accounts
for a combination of both 2.4G and 5G bands) and adding a bounds check
when writing to our statistics buffer.
Due to problem (b), we still might not properly report all known survey
information (e.g., with "iw <dev> survey dump"), since duplicate results
(or otherwise "larger than expected" results) will cause some
truncation. But that's a problem for a future bugfix.
(And because of this known deficiency, only log the excess at the WARN
level, since that isn't visible by default in this driver and would
otherwise be a bit too noisy.)

nfp: set config bit (ifup/ifdown) on netdev open/close
When a netdev (PF netdev or representor) is opened or closed, set the
physical port config bit appropriately - which powers UP/DOWN the PHY
module for the physical interface.
The PHY is powered first in the HW/FW configuration step when opening
the netdev and again last in the HW/FW configuration step when closing
the netdev.
This is only applicable when there is a physical port associated with
the netdev and if the NSP support this. Otherwise we silently ignore

On resume, the ibmvnic driver will fail to resume normal operation.
The main crq gets closed on suspend by the vnic server and doesn't get

the main crq comes in after the driver has been suspended.
This patch resolves the issue by removing the calls to kick the receive

handler. This will ensure that we see the transport event necessary to

the PF driver issues a VFR_ALLOC FW cmd that returns "cfa_code"
and "cfa_action" values. The FW sets up the filter tables in such
a way that VF traffic by default (in absence of other rules)
gets punted to the parent PF. The cfa_code value in the RX-compl
informs the driver of the source VF. For traffic being transmitted
from the VF-rep, the TX BD is tagged with a cfa_action value that
informs the HW to punt it to the corresponding VF.

Merge branch 'udp-tunnel-offloads-toggle'
Sabrina Dubroca says:
====================
Allow to switch off UDP-based tunnel offloads per netdevice
This patchset adds a new netdevice feature to toggle RX offloads of
UDP-based tunnel via ethtool. This is useful if the offload is causing
issues, for example if the hardware is buggy.
The feature is added to all devices providing the ->ndo_udp_tunnel_add
op, and enabled by default to preserve current behavior.
When the administrator disables this feature on a device, all
currently offloaded ports are cleared from the device. When the
feature is turned on, the stack notifies the device about all current
ports.
v2:
- rename feature bit to NETIF_F_RX_UDP_TUNNEL_PORT
- rename ethtool feature to rx-udp_tunnel-port-offload
====================

net: call udp_tunnel_get_rx_info when NETIF_F_RX_UDP_TUNNEL_PORT is toggled
NETIF_F_RX_UDP_TUNNEL_PORT is special, in that we need to do more than
just flip the bit in dev->features. When disabling we must also clear
currently offloaded ports from the device, and when enabling we must
tell the device to offload the ports it can.
Because vxlan stores its sockets in a hashtable and they are inserted at
the head of per-bucket lists, switching the feature off and then on can
result in a different set of ports being offloaded (depending on the
HW's limits).

geneve: add rtnl changelink support
This patch adds changelink rtnl operation support for geneve devices
and the code changes involve:
- added geneve_quiesce() which quiesces the geneve device data path
for both TX and RX. This lets us perform the changelink operation
atomically w.r.t data path. Also added geneve_unquiesce() to
reverse the operation of geneve_quiesce().
- refactor geneve_newlink into geneve_nl2info to be used by both
geneve_newlink and geneve_changelink
- geneve_nl2info takes a changelink boolean argument to isolate
changelink checks.
- Allow changing only a few attributes (ttl, tos, and remote tunnel
endpoint IP address (within the same address family)):
- return -EOPNOTSUPP for attributes that cannot be changed for
now. Incremental patches can make the non-supported one
available in the future if needed.
