The driver is misconfiguring the hardware for some values of MTU such that
it could use multiple descriptors to receive a packet when it could have
simply used one.
Change the driver to use a round-up instead of the result of a shift, as
the shift can truncate the lower bits of the size, and result in the
problem noted above. It also aligns this driver with similar code in i40e.
The insidiousness of this problem is that everything works with the wrong
size, it's just not working as well as it could, as some MTU sizes end up
using two or more descriptors, and there is no way to tell that is
happening without looking at ice_trace or a bus analyzer.

Gustavo already tried to fix those back in 2021[0][1]. Unfortunately,
a VM can run a different kernel than the host, meaning that those
structures are sorta ABI.
However, it is possible to have proper flex arrays + struct_size()
calculations and still send the very same messages with the same sizes.
The common rule is:
elem[1] -> elem[]
size = struct_size() + <difference between the old and the new msg size>
The "old" size in the current code is calculated 3 different ways for
10 virtchnl structures total. Each commit addresses one of the ways
cumulatively instead of per-structure.
I was planning to send it to -net initially, but given that virtchnl was
renamed from i40evf and got some fat style cleanup commits in the past,
it's not very straightforward to even pick appropriate SHAs, not
speaking of automatic portability. I may send manual backports for
a couple of the latest supported kernels later on if anyone needs it
at all.

Commit 885fe6932a11 ("ice: Add support for SMA control multiplexer")
accidentally placed all of the E810T SMA control functions in the middle of
the device agnostic functions section of ice_ptp_hw.c
This works fine, but makes it harder for readers to follow. The
ice_ptp_hw.c file is laid out such that each hardware family has the
specific functions in one block, with the access functions placed at the
end of the file.
Move the E810T functions so that they are in a block just after the E810
functions. Also move the ice_get_phy_tx_tstamp_ready_e810 which got added
at the end of the E810T block.
This keeps the functions laid out in a logical order and avoids intermixing
the generic access functions with the device specific implementations.

Finally, fix 3 structures which are allocated technically correctly,
i.e. the calculated size equals to the one that struct_size() would
return, except for sizeof(). For &virtchnl_vlan_filter_list_v2, use
the same approach when there are no enough space as taken previously
for &virtchnl_vlan_filter_list, i.e. let the maximum size be calculated
automatically instead of trying to guestimate it using maths.

There are five virtchnl structures, which are allocated and checked in
the code as `nents + 1`, meaning that they always have memory for one
excessive element regardless of their actual number. This comes from
that their sizeof() includes space for 1 element and then they get
allocated via struct_size() or its open-coded equivalents, passing
the actual number of elements.
Expand virtchnl_struct_size() to handle such structures and replace
those 1-elem arrays with proper flex ones. Also fix several places
which open-code %IAVF_VIRTCHNL_VF_RESOURCE_SIZE. Finally, let the
virtchnl_ether_addr_list size be computed automatically when there's
no enough space for the whole list, otherwise we have to open-code
reverse struct_size() logics.

The two most problematic virtchnl structures are virtchnl_rss_key and
virtchnl_rss_lut. Their "flex" arrays have the type of u8, thus, when
allocating / checking, the actual size is calculated as `sizeof +
nents - 1 byte`. But their sizeof() is not 1 byte larger than the size
of such structure with proper flex array, it's two bytes larger due to
the padding. That said, their size is always 1 byte larger unless
there are no tail elements -- then it's +2 bytes.
Add virtchnl_struct_size() macro which will handle this case (and later
other cases as well). Make its calling conv the same as we call
struct_size() to allow it to be drop-in, even though it's unlikely to
become possible to switch to generic API. The macro will calculate a
proper size of a structure with a flex array at the end, so that it
becomes transparent for the compilers, but add the difference from the
old values, so that the real size of sorta-ABI-messages doesn't change.
Use it on the allocation side in IAVF and the receiving side (defined
as static inline in virtchnl.h) for the mentioned two structures.

On some I219 devices, ethernet cable plugging detection only works once
from PCI D3 state. Subsequent cable plugging does set PME bit correctly,
but device still doesn't get woken up.
Since I219 connects to the root complex directly, it relies on platform
firmware (ACPI) to wake it up. In this case, the GPE from _PRW only
works for first cable plugging but fails to notify the driver for
subsequent plugging events.
The issue was originally found on CNP, but the same issue can be found
on ADL too. So workaround the issue by continuing use PME poll after
first ACPI wake. As PME poll is always used, the runtime suspend
restriction for CNP can also be removed.

i40e_profile_aq_section
One-element and zero-length arrays are deprecated. So, replace
one-element array in struct i40e_profile_aq_section with

Add fdir_fltr_lock locking in unprotected places.
The change in iavf_fdir_is_dup_fltr adds a spinlock around a loop which
iterates over all filters and looks for a duplicate. The filter can be
removed from list and freed from memory at the same time it's being
compared. All other places where filters are deleted are already
protected with spinlock.
The remaining changes protect adapter->fdir_active_fltr variable so now
all its uses are under a spinlock.

Access to shared variables through hrtimer requires locking in order
to protect the variables because actions to write into these variables
(oper_gate_closed, admin_gate_closed, and qbv_transition) might potentially
occur simultaneously. This patch provides a locking mechanisms to avoid

Refactor __ice_aq_get_set_rss_lut() to improve reader experience and limit
misuse scenarios (undesired LUT size for given LUT type).
Allow only 3 RSS LUT type+size variants:
PF LUT sized 2048, GLOBAL LUT sized 512, and VSI LUT sized 64, which were
used on default flows prior to this commit.
Prior to the change, code was mixing the meaning of @params->lut_size and
@params->lut_type, flag assigning logic was cryptic, while long defines
made everything harder to follow.
Fix that by extracting some code out to separate helpers.
Drop some of "shift by 0" statements that originated from Intel's
internal HW documentation.
Drop some redundant VSI masks (since ice_is_vsi_valid() gives "valid" for
up to 0x300 VSIs).
After sweeping all the defines out of struct ice_aqc_get_set_rss_lut,
it fits into 7 lines.
Finally apply some cleanup to the callsite
(use of the new enums, tmp var for lengthy bit extraction).
Note that flags for 128 and 64 sized VSI LUT are the same,
and 64 is used everywhere in the code (updated to new enum here), it just
happened that there was 128 in flag name.
__ice_aq_get_set_rss_key() uses the same VSI valid bit, make constant
common for it and __ice_aq_get_set_rss_lut().

enum ice_pkt_flags contains values such as ICE_PKT_FLAGS_VLAN and
ICE_PKT_FLAGS_TUNNEL, but actually the flags words which they refer to
contain a range of unrelated values - e.g. word 0 (ICE_PKT_FLAGS_VLAN)
contains fields such as from_network and ucast, which have nothing to do
with VLAN. Rename each enum value to ICE_PKT_FLAGS_MDID<number>, so it's
clear in which flags word does some value reside.

Currently it is possible to create a filter which breaks TX traffic, e.g.:
tc filter add dev $PF1 ingress protocol ip prio 1 flower ip_proto udp
dst_port $PORT action mirred egress redirect dev $VF1_PR
This adds a rule which might match both TX and RX traffic, and in TX path
the PF will actually receive the traffic, which breaks communication.
To fix this, add a match on direction metadata flag when adding a tc rule.
Because of the way metadata is currently handled, a duplicate lookup word
would appear if VLAN metadata is also added. The lookup would still work
correctly, but one word would be wasted. To prevent it, lookup 0 now always
contains all metadata. When any metadata needs to be added, it is added to
lookup 0 and lookup count is not incremented. This way, two flags residing
in the same word will take up one word, instead of two.
Note: the drop action is also affected, i.e. it will now only work in one
direction.
