If we have RFC rules in adapter->nfc_rule_list when the IGC driver
is unloaded, all rules are leaked. This patch fixes the issue by
introducing the helper igc_flush_nfc_rules() and calling it in
igc_remove(). It also updates igc_set_features() so is reuses the
new helper instead of re-implementing it.

Current implementation of igc_ethtool_update_nfc_rule() is a bit
convoluted since it handles too many things: rule lookup, deletion
and addition. This patch breaks it into three functions so we simplify
the code and improve code reuse.
Code related to rule lookup is refactored out to a new function called
igc_get_nfc_rule().
Code related to rule addition is refactored out to a new function called
igc_add_nfc_rule(). This function enables the rule in hardware and adds
it to the adapter's list.
Code related to rule deletion is refactored out to a new function called
igc_del_nfc_rule(). This function disables the rule in hardware, removes
it from adapter's list, and deletes it.
As a byproduct of this refactoring, igc_enable_nfc_rule() and
igc_disable_nfc_rule() are moved to igc_main.c since they are not used
in igc_ethtool.c anymore, and igc_restore_nfc_rules() and igc_nfc_rule_
exit() are moved around to avoid forward declaration.
Also, since this patch already touches igc_ethtool_get_nfc_rule(), it
takes the opportunity to remove the 'match_flags' check. Empty flags
are not allowed to be added so no need to check that.

When network interface is brought up, the driver re-enables the NFC
rules previously configured. However, this is done in reverse order
the rules were added and hardware filters are configured differently.
For example, consider the following rules:
$ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:AA queue 0
$ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:BB queue 1
$ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:CC queue 2
$ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:DD queue 3
RAL/RAH registers are configure so filter index 1 has address ending
with AA, filter index 2 has address ending in BB, and so on.
If we bring the interface down and up again, RAL/RAH registers are
configured so filter index 1 has address ending in DD, filter index 2
has CC, and so on. IOW, in reverse order we had before bringing the
interface down.
This issue can be fixed by traversing adapter->nfc_rule_list in
backwards when restoring the rules. Since hlist doesn't support
backwards traversal, this patch replaces it by list_head and fixes
igc_restore_nfc_rules() accordingly.

Multicast MAC addresses are valid address for NFC rules but
igc_add_mac_filter() is currently rejecting them. In fact, the I225
controller doesn't impose any constraint on the address value so this
patch gets rid of the address validation check in MAC filter APIs.

When the 'loc' argument is passed in ethtool, the input rule overwrites
any rule present in that location. In this situation we must disable the
old rule otherwise it is left enabled in hardware. This patch fixes

old rule, no matter the value of 'input' argument.

Current implementation of igc_ethtool_add_nfc_rule() is quite long and a
bit convoluted so this patch does a code refactoring to improve the
code.
Code related to NFC rule object initialization is refactored out to the
local helper function igc_ethtool_init_nfc_rule(). Likewise, code
related to NFC rule validation is refactored out to another local
helper, igc_ethtool_is_nfc_rule_valid().
RX_CLS_FLOW_DISC check is removed since it is redundant. The macro is
defined as the max value fsp->ring_cookie can have, so checking if
fsp->ring_cookie >= adapter->num_rx_queues is already sufficient.
Finally, some log messages are improved or added, and obvious comments
are removed.

100GbE Intel Wired LAN Driver Updates 2020-05-21
This series contains updates to ice driver only. Several of the changes
are fixes, which could be backported to stable, of which, only one was
marked for stable because of the memory leak potential.
Jake exposes the information in the flash memory used for link
management, which is called the netlist module.
Henry and Tony add support for tunnel offloads.
Brett adds promiscuous support in VF's which is based on VF trust and
the new vf-true-promisc flag.
Avinash fixes an issue where a transmit timeout for a queue that belongs
to a PFC enabled TC is not a true transmit timeout, but because the PFC
is in action.
Dave fixes the check for contiguous TCs to allow for various UP2TC
mapping configurations. Also fixed an issue when changing the pause
parameters would could multiple link drop/down's in succession, which in
turn caused the firmware to not generate a link interrupt for the driver
to respond to.
Anirudh (Ani) fixed a potential race condition in probe/open due to a
bit being cleared too early.
Lihong updates an error message to make it more meaningful instead of
just printing out the numerical value of the status/error code. Also
fixed an incorrect return value if deleting a filter does not find a
match to delete or when adding a filter that already exists.
Karol fixes casting issues and precision loss in the driver.
Jesse make the sign usage more consistent in the driver by making sure
all instances of vf_id are unsigned, since it can never be negative.
Eric fixes a potential memory leak in ice_add_prof_id_vsig() where was
not cleaning up resources properly when an error occurs.
Michal to help organize the filtering code in the driver, refactor the
code into a separate file and add functions to prepare the filter
information.
Bruce cleaned up a conditional statement that always resulted in true
and provided a comment to make it more obvious. Also cleaned up
redundant code checks.
Tony helps with potential namespace issues by renaming a 'ice' specific
function with the driver name prepended.

As soon as the driver registers the PF netdev, userspace utilities
like NetworkManager try to bring up the associated interface. When
this happens, the driver may not have finished initializing fully,
resulting in a bunch of errors in the interface up flow.
The driver already has a mechanism to indicate if it's not up yet;
by setting the __ICE_DOWN bit in pf->state, but this bit gets
cleared too early in the current flow. So clear this bit only when
the driver is fully up. Also check for the same bit in the ice_open
flow, and return -EBUSY if the bit is set.
Also in ice_open, replace references of vsi->back with a local
variable.

Currently, the ice driver is setting a PHY configuration,
which causes a link drop, and then additionally it calls
for a nway_reset, which restarts auto-negotiation on the
link, which also causes a link drop. These two link
events in such close timing is causing the FW to not be
able to generate a link interrupt for the driver to
respond to.
Remove the unnecessary auto-negotiation restart from the
set pauseparams flow. Also remove error path that
would have performed an ice_down/ice_up as that is
also unnecessary.

When there's a Tx timeout for a queue which belongs to a PFC enabled TC,
then it's not because the queue is hung but because PFC is in action.
In PFC, peer sends a pause frame for a specified period of time when its
buffer threshold is exceeded (due to congestion). Netdev on the other
hand checks if ACK is received within a specified time for a TX packet, if
not, it'll invoke the tx_timeout routine.

Implement promiscuous support for VF VSIs. Behaviour of promiscuous support
is based on VF trust as well as the, introduced, vf-true-promisc flag.
A trusted VF with vf-true-promisc disabled will be the default VSI, which
means that all traffic without a matching destination MAC address in the
device's internal switch will be forwarded to this VF VSI.
A trusted VF with vf-true-promisc enabled will go into "true promiscuous
mode". This amounts to the VF receiving all ingress and egress traffic
that hits the device's internal switch.
An untrusted VF will only receive traffic destined for that VF.
The vf-true-promisc-support flag cannot be toggled while any VF is in
promiscuous mode. This flag should be set prior to loading the iavf driver
or spawning VF(s).

Every time we access the 'etype' and 'vlan_tci' fields from struct
igc_nfc_filter to enable or disable filters in hardware we have to
convert them from big endian to host order so it makes more sense to
simply have these fields in host order.
The byte order conversion should take place in igc_ethtool_get_nfc_
rule() and igc_ethtool_add_nfc_rule(), which are called by .get_rxnfc
and .set_rxnfc ethtool ops, since ethtool subsystem is the one who deals
