XDP statistics are reported in ethtool, in total and per ring,
as follows:
- xdp_drop: the number of packets dropped by xdp.
- xdp_tx: the number of packets forwarded by xdp.
- xdp_tx_full: the number of times an xdp forward failed
due to a full tx xdp ring.
In addition, all packets that are dropped/forwarded by XDP
are no longer accounted in rx_packets/rx_bytes of the ring,
so that they count traffic that is passed to the stack.

Separately manage the two types of TX rings: regular ones, and XDP.
Upon an XDP set, do not borrow regular TX rings and convert them
into XDP ones, but allocate new ones, unless we hit the max number
of rings.
Which means that in systems with smaller #cores we will not consume
the current TX rings for XDP, while we are still in the num TX limit.
XDP TX rings counters are not shown in ethtool statistics.
Instead, XDP counters will be added to the respective RX rings
in a downstream patch.

The current Rx timestamp hang logic is not very robust because it does
not notice a register is hung until all four timestamps have been
latched and we wait a full 5 seconds. Replace this logic with a newer Rx
hang detection based on storing the jiffies when we first notice
a receive timestamp event. We store each register's time separately,
along with a flag indicating if it is currently latched. Upon first
transitioning to latch, we will update the latch_events[i] jiffies
value. This indicates the time we first noticed this event. The watchdog
routine will simply check that the either the flag has been cleared, or
we have passed at least one second. In this case, it is able to clear
the Rx timestamp register under the assumption that it was for a dropped
frame. The benefit if this strategy is that we should be able to
detect and clear out stalled RXTIME_H registers before we exhaust the
supply of 4, and avoid complete stall of Rx timestamp events.

The spinlock_t is overkill here, especially use of spin_lock_irqsave,
since every PTP access will halt hardirqs. Notice that the only places
which need the SYSTIME value are user context and are capable of sleeping.
Thus, it is safe to use a mutex here instead of the spinlock.

When hardware has taken a timestamp for a received packet, it indicates
which RXTIME register the timestamp was placed in by some bits in the
receive descriptor. It uses 3 bits, one to indicate if the descriptor
index is valid (ie: there was a timestamp) and 2 bits to indicate which
of the 4 registers to read. However, the driver currently does not check
the TSYNVALID bit and only checks the index. It assumes a zero index
means no timestamp, and a non zero index means a timestamp occurred.
While this appears to be true, it prevents ever reading a timestamp in
RXTIME[0], and causes the first timestamp the device captures to be
ignored.
Fix this by using the TSYNVALID bit correctly as the true indicator of
whether the packet has an associated timestamp.
Also rename the variable rsyn to tsyn as this is more descriptive and
matches the register names.

We determine that a VSI is in vlan_mode whenever it has any filters
with a VLAN other than -1 (I40E_VLAN_ALL). The previous method of doing
so was to perform a loop whenever we needed the check. However, we can
notice that only place where filters are added (i40e_add_filter) can
change the condition from false to true, and the only place we can
return to false is in i40e_vsi_sync_filters_subtask. Thus, we can remove
the loop and use a boolean directly.
Doing this avoids looping over filters repeatedly especially while we're
already inside a loop over all the filters. This should reduce the
latency of filter operations throughout the driver.

Currently there exists a bug where adding at least one VLAN and then
removing all VLANs leaves the mac filters for the VSI with an incorrect
value for 'vid' which indicates the mac filter's VLAN status.
The current implementation for handling the removal of VLANs is wrong
for a couple reasons. The first is that when i40e_vsi_kill_vlan
iterates through the MAC filters, it fails to account for the MAC filter
status; i.e. it's not accommodating for filters that are about to be
deleted. The second problem is that MAC filters can be deleted in other
places (specifically i40e_set_rx_mode). Thus if it occurs that all the
VLAN MAC filters get deleted we need to switch out of VLAN mode, but the
code path through i40e_vsi_kill_vlan has already been executed and we're
now stuck in VLAN mode.
This patch fixes the issue by removing the check from i40e_vsi_kill_vlan
and puts the check instead in i40e_sync_vsi_filters where we're
guaranteed to see all filter deletions and can properly detect when we
need to switch out of VLAN mode.

When inside a loop where we call i40e_del_filter we use an O(n^2)
pattern where i40e_del_filter calls i40e_find_filter for us. We can
avoid this O(n^2) logic by factoring a function, __i40e_del_filter() out
from the i40e_del_filter code. This allows us to re-use the delete logic
where appropriate without having to search for the filter twice.
This new function benefits several functions including i40e_vsi_add_vlan,
i40e_vsi_kill_vlan, i40e_del_mac_vlan_all, and i40e_vsi_release.

When adding new MAC address filters, the driver determines if it should
behave in VLAN mode (where all MAC addresses get assigned to every
existing VLAN) or in non-VLAN mode where MAC addresses get assigned the
VLAN_ANY identifier. Under some circumstances it is possible that a VLAN
has been marked for removal (such that all filters of that VLAN are set
to I40E_FILTER_REMOVE), and a subsequent call to i40e_put_mac_in_vlan
may occur prior to the driver subtask that syncs filters to the
hardware.
In this case, we may add filters to the new removed VLAN, even though it
should have been removed. This is most obvious when first adding a new
VLAN. We will delete all filters which are in I40E_VLAN_ANY (-1) and
then re-add them as in VLAN 0 (untagged). Then before we sync filters,
we will add new MAC address filter, which will be added to every VLAN
that exists. Unfortunately, this will include I40E_VLAN_ANY, so we will
end up incorrectly adding filters to the -1 VLAN. This can be fixed by
simply skipping all filters which are marked for removal.
A similar check is not necessary in i40e_del_mac_all_vlan, since we are
deleting, and any filter which we find already marked for removal would
simply be deleted again, which doesn't cause any issues.

When a PVID has been assigned to a VSI, the function
i40e_put_mac_in_vlan arbitrarily modifies all filters
to have the same VLAN. This is obviously incorrect
because it could be modifying active filters without
putting them into the NEW state. The correct method
is to remove then re-add filters which is already done
in the code where we assign the PVID.
Fix this issue and a few other minor nits at the same
time. First, when we have a PVID don't even bother
looping and simply add the filter with the PVID immediately.
In the case of the loop, we now can remove several checks.
We also don't need to use i40e_find_filter first before
calling i40e_add_filter, since i40e_add_filter implicitly
does a lookup already.
Finally, update the return semantics of this function so
that on failure to add a filter it returns NULL, but on
success, it returns the last filter added. Otherwise,
we're just returning the last filter in the list. An
alternative fix might be to return 0 or an error code,
but this is pretty invasive to every call site.

The kernel provides __dev_uc_sync and __dev_mc_sync in order for drivers
which need individual notification of add and delete for each filter.
These functions allow us to vastly simplify our .set_rx_mode handler. We
need to implement two functions for sync and unsync which add and remove
filters respectively.
This change avoids a very complex and inefficient algorithm which
resulted in an abnormal latency for the .set_rx_mode NDO operation. The
resulting code after this change is more readable, more efficient, and
less code.
Due to the callback signature used by these functions we also must

Originally the is_vf and is_netdev fields were added in order to
distinguish between VF and netdev filters in a single VSI. However, it
can be noted that we use separate VSI for SRIOV VFs and for netdev VSI.
Thus, since a single VSI should only ever have one type of filter, we
can simply remove the checks and remove the typing.
In a similar fashion, we can note that the only remaining way to get
multiple filters of a single type is through a debug command that was
added to debugfs. This command is useless in practice, and results in
causing bugs if we keep counter tracking but lose the is_vf and
is_netdev protections as desired above.
Since the only time we'd actually have a counter value besides 0 and
1 is through use of this debugfs hook, we can remove this unnecessary
command, and the entire counter logic it required.
We vastly simplify mac filters by removing
(a) the distinction between VF and netdev filters
(b) counting logic
(c) the ability to add and remove filters bypassing the stack via debugfs
