Currently the ERPs are tracked internally in a hashtable. Benefit from
the newly introduced objagg library and use it to track ERPs. At this
point, there is no nesting of objects done, as the delta_create callback
always returns -EOPNOTSUPP. On the way, add "mask" into ERP mask get and
set functions and struct names.

We can't use SAR Geo if basic SAR is not enabled, since the SAR Geo
tables define offsets in relation to the basic SAR table in use.
To fix this, make iwl_mvm_sar_init() return one in case WRDS is not
available, so we can skip reading WGDS entirely.

When the firmware starts, it doesn't have any regulatory
information, hence it uses the world wide limitations. The
driver can feed the firmware with previous knowledge that
was kept in the driver, but the firmware may still not
update its internal tables.
This happens when we start a BSS interface, and then the
firmware can change the regulatory tables based on our
location and it'll use more lenient, location specific
rules. Then, if the firmware is shut down (when the
interface is brought down), and then an AP interface is
created, the firmware will forget the country specific
rules.
The host will think that we are in a certain country that
may allow channels and will try to teach the firmware about
our location, but the firmware may still not allow to drop
the world wide limitations and apply country specific rules
because it was just re-started.
In this case, the firmware will reply with MCC_RESP_ILLEGAL
to the MCC_UPDATE_CMD. In that case, iwlwifi needs to let
the upper layers (cfg80211 / hostapd) know that the channel
list they know about has been updated.

We already have a workaround for a couple of switches whose internal
PHYs only have the Marvel OUI, but no model number. We detect such
PHYs and give them the 6390 ID as the model number. However the
mv88e6161 has two SERDES interfaces in the same address range as its
internal PHYs. These suffer from the same problem, the Marvell OUI,
but no model number. As a result, these SERDES interfaces were getting
the same PHY ID as the mv88e6390, even though they are not PHYs, and
the Marvell PHY driver was trying to drive them.
Add a special case to stop this from happen.

100GbE Intel Wired LAN Driver Updates 2018-11-13
This series contains updates to the ice driver only.
Brett cleans up debug print messages by removing useless or duplicate
messages, and make sure we assign the hardware head pointer to head
instead of the software head pointer. Resolved an issue when disabling
SRIOV we were trying to stop queues multiple times, so make sure we
disable SRIOV before stopping transmit and receive queues for VF.
Tony fixes a potential NULL pointer dereference during a VF reset.
Anirudh resolves an issue where we were releasing the VSI before
removing the VSI scheduler node, which was resulting in an error "Failed
to set LAN Tx queue context, error: -1". Also fixed the guaranteed
number of VSIs available and used by discovering the device
capabilities to determine the 'guar_num_vsi' per function, rather than
always using the theoretical max number of VSIs every time.
Dave avoids a deadlock by nesting RTNL locking, so added a boolean to
determine if the RTNL lock is already held.
Lev fixes bad mask values which would break compilation.
Piotr increases the receive queue disable timeout since it can take
additional time to finish all pending queue requests.
Usha resolves an issue of VLAN priority tagged traffic not appearing on
all traffic classes, which was causing ETS bandwidth shaping to not work
as expected.
Henry fixes the reset path to cleanup the old scheduler tree before
rebuilding it.
Md Fahad removes a unnecessary check which was causing a driver load
error on platforms with more than 128 cores.

The software counter structure is defined in both the CP ring's structure
and the NQ ring's structure on the new devices. The legacy code adds the
counter to the CP ring's structure and the counter won't get displayed
since the ethtool code is looking at the NQ ring's structure.
Since all other counters are contained in the NQ ring's structure, it
makes more sense to count rx_l4_csum_errors in the NQ.

Recent commit has added the reservation of RSS context. This requires
bnxt_hwrm_vnic_qcaps() to be called before allocating any RSS contexts.
The bnxt_hwrm_vnic_qcaps() call sets up proper flags that will
determine how many RSS contexts to allocate to support NTUPLE.
This causes a regression that too many RSS contexts are being reserved
and causing resource shortage when enabling many VFs. Fix it by calling
bnxt_hwrm_vnic_qcaps() earlier.

Move IRQ configuration for IP101A/G from config_init to config_intr
callback. Reasons:
1. This allows phylib to disable interrupts if needed.
2. Icplus was the only driver supporting interrupts w/o defining a
config_intr callback. Now we can add a phylib plausibility check
disabling interrupt mode if one of the two irq-related callbacks
isn't defined.
I don't own hardware with this PHY, and the change is based on the
datasheet for IP101A LF (which is supposed to be register-compatible
with IP101A/G). Change is compile-tested only.

If a TX hang occurs, we attempt to recover by incrementally resetting.
If we're starved for CPU time, it's possible the reset doesn't actually
complete (or even fire) before another tx_timeout fires causing us to
fly through the different resets without actually doing them.
This adds a bit to set and check if a timeout recovery is already
pending and, if so, bail out of tx_timeout. The bit will get cleared at
the end of i40e_rebuild when reset is complete.

The i40e driver complains about unprivileged VFs trying to configure
promiscuous mode each time a VF reset occurs. This isn't the fault of
the poor VF driver - the PF driver itself is making the request.
To fix this, skip the privilege check if the request is to disable all
promiscuous activity. This gets rid of the bogus message, but doesn't
affect privilege checks, since we really only care if the unprivileged
VF is trying to enable promiscuous mode.

Add support of L3/L4 5-tuple {protocol, src-ip, dst-ip, src-port, dst-port}
filters. Mask is not supported. Src-port and dst-port are only compared for
TCP/UDP/SCTP packets. Both IPv4 and IPv6 are supported.
The supported actions are the drop and the queue assignment.
Due to fixed order of the rules in the NIC, the location 32-39 are
reserved for L3/L4 5-tuple filters. The locations 32 and 36 are
reserved for IPv6 filters.
Examples:
sudo ethtool -N eth0 flow-type ip6 src-ip 2001:db8:0:f101::2 \
dst-ip 2001:db8:0:f101::5 action -1 loc 36
sudo ethtool -N eth0 flow-type udp4 src-ip 10.0.0.4 \
dst-ip 10.0.0.7 src-port 2000 dst-port 2001 action 2 loc 32

Each slave has it's own receive timestamp filter. But cpts rx/tx
timestamp enable flags are used to allow ts retrieve only for one
user. This limitation causes data path redundancy and setting overlap
if cpsw module is in dual-mac mode for instance.
If rx ts is enabled only for one port - the second interface must expect
every incoming packet to be PTP packet w/o absolutely any reason, and if
it's PTP - do unneeded stuff, as rx filter for second port is not set
and cpts fifo is not supposed to contain appropriate ts event.
That's not correct.
So, to fix control overlap and avoid redundant CPU cycles, the patch
splits rx/tx ts enable flags between network devices. After the patch,
PTP timestamping still should be used for only one port (or PTP id
counter has to be different for both ports as cpts IP is common).
