100GbE Intel Wired LAN Driver Updates 2021-02-05

This series contains updates to ice driver only.

Jake adds adds reporting of timeout length during devlink flash and
implements support to report devlink info regarding the version of
firmware that is stored (downloaded) to the device, but is not yet active.
ice_devlink_info_get will report "stored" versions when there is no
pending flash update. Version info includes the UNDI Option ROM, the
Netlist module, and the fw.bundle_id.

Gustavo A. R. Silva replaces a one-element array to flexible-array
member.

Bruce utilizes flex_array_size() helper and removes dead code on a check
for a condition that can't occur.

v2:
* removed security revision implementation, and re-ordered patches to
account for this removal
* squashed patches implementing ice_read_flash_module to avoid patches
refactoring the implementation of a previous patch in the series
* modify ice_devlink_info_get to always report "stored" versions instead
of only reporting them when a pending flash update is ready.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: remove dead code
  ice: use flex_array_size where possible
  ice: Replace one-element array with flexible-array member
  ice: display stored UNDI firmware version via devlink info
  ice: display stored netlist versions via devlink info
  ice: display some stored NVM versions via devlink info
  ice: introduce function for reading from flash modules
  ice: cache NVM module bank information
  ice: introduce context struct for info report
  ice: create flash_info structure and separate NVM version
  ice: report timeout length for erasing during devlink flash

====================
Netfilter/IPVS updates for net-next

1) Remove indirection and use nf_ct_get() instead from nfnetlink_log
   and nfnetlink_queue, from Florian Westphal.

2) Add weighted random twos choice least-connection scheduling for IPVS,
   from Darby Payne.

3) Add a __hash placeholder in the flow tuple structure to identify
   the field to be included in the rhashtable key hash calculation.

4) Add a new nft_parse_register_load() and nft_parse_register_store()
   to consolidate register load and store in the core.

5) Statify nft_parse_register() since it has no more module clients.

6) Remove redundant assignment in nft_cmp, from Colin Ian King.

* git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next:
  netfilter: nftables: remove redundant assignment of variable err
  netfilter: nftables: statify nft_parse_register()
  netfilter: nftables: add nft_parse_register_store() and use it
  netfilter: nftables: add nft_parse_register_load() and use it
  netfilter: flowtable: add hash offset field to tuple
  ipvs: add weighted random twos choice algorithm
  netfilter: ctnetlink: remove get_ct indirection

      There's no benefit in trying to disable interrupts if NAPI is
scheduled already. This allows us to save a PCI write in this case.

      net/packet: Improve the comment about LL header visibility criteria · 21c85974
      Xie He authored 
      The "dev_has_header" function, recently added in
commit d5496990 ("net/packet: fix packet receive on L3 devices
without visible hard header"),
is more accurate as criteria for determining whether a device exposes
the LL header to upper layers, because in addition to dev->header_ops,
it also checks for dev->header_ops->create.

When transmitting an skb on a device, dev_hard_header can be called to
generate an LL header. dev_hard_header will only generate a header if
dev->header_ops->create is present.

====================
net: ipa: a mix of small improvements

Version 2 of this series restructures a couple of the changed
functions (in patches 1 and 2) to avoid blocks of indented code
by returning early when possible, as suggested by Jakub.  The
description of the first patch was changed as a result, to better
reflect what the updated patch does.  It also fixes one spot I
identified when updating the code, where gsi_channel_stop() was
doing the wrong thing on error.

The original description for this series is below.

This series contains a sort of unrelated set of code cleanups.

The first two are things I wanted to do in a series that updated
some NAPI code recently.  I didn't want to change things in a way
that affected existing testing so I set these aside for later
(i.e., now).

The third makes a change to event ring handling that's similar to
what was done a while back for channels.  There's little benefit to
cacheing the current state of an event ring, so with this we'll just
fetch the state from hardware whenever we need it.

The fourth patch removes the definitions of two unused symbols.

The fifth replaces a count that is always 0 or 1 with a Boolean.

The sixth removes a build-time validation check that doesn't really
provide benefit.

And the last one fixes a problem (in two spots) that could cause a
build-time check to fail "bogusly".

      net: ipa: avoid field overflow · cd115009
      Alex Elder authored 
      It's possible that the length passed to ipa_header_size_encoded()
is larger than what can be represented by the HDR_LEN field alone
(starting with IPA v4.5).  If we attempted that, u32_encode_bits()
would trigger a build-time error.

Avoid this problem by masking off high-order bits of the value
encoded as the lower portion of the header length.

The same sort of problem exists in ipa_metadata_offset_encoded(),
so implement the same fix there.

      net: ipa: get rid of status size constraint · 48735374
      Alex Elder authored 
      There is a build-time check that the packet status structure is a
multiple of 4 bytes in size.  It's not clear where that constraint
comes from, but the structure defines what hardware provides so its
definition won't change.  Get rid of the check; it adds no value.

      net: ipa: use a Boolean rather than count when replenishing · 9af5ccf3
      Alex Elder authored 
      The count argument to ipa_endpoint_replenish() is only ever 0 or 1,
and always will be (because we always handle each receive buffer in
a single transaction).  Rename the argument to be add_one and change
it to be Boolean.

Update the function description to reflect the current code.

      net: ipa: remove two unused register definitions · d5bc5015
      Alex Elder authored 
      We do not support inter-EE channel or event ring commands.  Inter-EE
interrupts are disabled (and never re-enabled) for all channels and
event rings, so we have no need for the GSI registers that clear
those interrupt conditions.  So remove their definitions.

      net: ipa: do not cache event ring state · 3f77c926
      Alex Elder authored 
      An event ring's state only needs to be known when it is allocated,
reset, or deallocated.  We check an event ring's state both before
and after performing an event ring control command that changes
its state.  These are only issued at startup and shutdown, so there
is very little value in caching the state.

Stop recording a copy of the channel's last known state, and instead
fetch the true state from hardware whenever it's needed.  In such
cases, *do* record the state in a local variable, in case an error
message reports it (so the value reported is the value seen).

      net: ipa: synchronize NAPI only for suspend · b1750723
      Alex Elder authored 
      When stopping a channel, gsi_channel_stop() will ensure NAPI
polling is complete when it calls napi_disable().  So there is no
need to call napi_synchronize() in that case.

Move the call to napi_synchronize() out of __gsi_channel_stop()
and into gsi_channel_suspend(), so it's only used where needed.
