net/tls: remove the record tail optimization

For TLS device offload the tag/message authentication code are
filled in by the device. The kernel merely reserves space for
them. Because device overwrites it, the contents of the tag make
do no matter. Current code tries to save space by reusing the
header as the tag. This, however, leads to an additional frag
being created and defeats buffer coalescing (which trickles
all the way down to the drivers).

Remove this optimization, and try to allocate the space for
the tag in the usual way, leave the memory uninitialized.
If memory allocation fails rewind the record pointer so that
we use the already copied user data as tag.

Note that the optimization was actually buggy, as the tag
for TLS 1.2 is 16 bytes, but header is just 13, so the reuse
may had looked past the end of the page..

ipmr: remove hard code cache_resolve_queue_len limit

This is a re-post of previous patch wrote by David Miller[1].

Phil Karn reported[2] that on busy networks with lots of unresolved
multicast routing entries, the creation of new multicast group routes
can be extremely slow and unreliable.

The reason is we hard-coded multicast route entries with unresolved source
addresses(cache_resolve_queue_len) to 10. If some multicast route never
resolves and the unresolved source addresses increased, there will
be no ability to create new multicast route cache.

To resolve this issue, we need either add a sysctl entry to make the
cache_resolve_queue_len configurable, or just remove cache_resolve_queue_len
limit directly, as we already have the socket receive queue limits of mrouted
socket, pointed by David.

>From my side, I'd perfer to remove the cache_resolve_queue_len limit instead
of creating two more(IPv4 and IPv6 version) sysctl entry.

[1] https://lkml.org/lkml/2018/7/22/11
[2] https://lkml.org/lkml/2018/7/21/343

v3: instead of remove cache_resolve_queue_len totally, let's only remove
the hard code limit when allocate the unresolved cache, as Eric Dumazet
suggested, so we don't need to re-count it in other places.

v2: hold the mfc_unres_lock while walking the unresolved list in

====================
100GbE Intel Wired LAN Driver Updates 2019-09-05

This series contains updates to ice driver.

Brett fixes the setting of num_q_vectors by using the maximum number
between the allocated transmit and receive queues.

Anirudh simplifies the code to use a helper function to return the main
VSI, which is the first element in the pf->vsi array.  Adds a pointer
check to prevent a NULL pointer dereference.  Adds a check to ensure we
do not initialize DCB on devices that are not DCB capable.  Does some
housekeeping on the code to remove unnecessary indirection and reduce
the PF structure by removing elements that are not needed since the
values they were storing can be readily gotten from
ice_get_avail_*_count()'s.  Updates the printed strings to make it
easier to search the logs for driver capabilities.

Jesse cleans up unnecessary function arguments.  Updated the code to use
prefetch() to add some efficiency to the driver to avoid a cache miss.
Did some housekeeping on the code to remove the configurable transmit
work limit via ethtool which ended up creating performance overhead.
Made additional performance enhancements by updating the driver to start
out with a reasonable number of descriptors by changing the default to
2048.

Mitch fixes the reset logic for VFs by clearing VF_MBX_ARQLEN register
when the source of the reset is not PFR.

Lukasz updates the driver to include a similar fix for the i40e driver
by reporting link down for VF's when the PF queues are not enabled.

Akeem updates the driver to report the VF link status once we get VF
resources so that we can reflect the link status similarly to how the PF
reports link speed.

Ashish updates the transmit context structure based on recent changes to
the hardware specification.

Dave updates the DCB logic to allow a delayed registration for MIB
change events so that the driver is not accepting events before it is
ready for them.

====================
The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add the ability to use unaligned chunks in the AF_XDP umem. By
   relaxing where the chunks can be placed, it allows to use an
   arbitrary buffer size and place whenever there is a free
   address in the umem. Helps more seamless DPDK AF_XDP driver
   integration. Support for i40e, ixgbe and mlx5e, from Kevin and
   Maxim.

2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
   application can wake up the kernel for rx/tx processing which
   avoids busy-spinning of the latter, useful when app and driver
   is located on the same core. Support for i40e, ixgbe and mlx5e,
   from Magnus and Maxim.

3) bpftool fixes for printf()-like functions so compiler can actually
   enforce checks, bpftool build system improvements for custom output
   directories, and addition of 'bpftool map freeze' command, from Quentin.

4) Support attaching/detaching XDP programs from 'bpftool net' command,
   from Daniel.

5) Automatic xskmap cleanup when AF_XDP socket is released, and several
   barrier/{read,write}_once fixes in AF_XDP code, from Björn.

6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf
   inclusion as well as libbpf versioning improvements, from Andrii.

7) Several new BPF kselftests for verifier precision tracking, from Alexei.

8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya.

9) And more BPF kselftest improvements all over the place, from Stanislav.

10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub.

11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan.

iwlwifi: pcie: set iwl_trans->cfg later in the probe function

Instead of setting the cfg to iwl_trans already during allocation, set
it only later when we have had the time to decide which cfg to use.
This is part of the effort to be able to decide the cfg based on HW
revision and RF ID after iwl_trans_alloc() has been called.

For now, since we still have a bunch of code checking the HW revision
and the RF ID, we set iwl_trans->cfg early, even before we decided the
real cfg to use.  We only use the trans configuration at this point,
so this is fine for now.  In the future, the trans configuration will
be completely independent from the rest of the config structure, so
we'll be able to avoid this.

Additionally, we can't access the PRPH registers in iwl_trans_alloc()
anymore, so move the HW REV C-step check for family 8000 code later to
the probe function as well.  This step is probably not necessary, but
if that's the case it should be removed separately later on.

iwlwifi: support per-platform antenna gain

TX power limits as defined in the OTP assume the worst case scenario
in terms of the platform's atenna gain, but most platforms are below
that value so they can use more TX power without passing the regulatory
limit. If the platform indicates in the BIOS that it indeed has lower
gain, and the geographic location allows it, higher TX power can be
used. The driver reads the PPAG (Per-Platform Antenna Gain) data from
BIOS (if it exists), validates it and sends the appropriate command to
the FW. This flow happens once at FW init, in case of suspend/resume
there is no need to read again from BIOS as we save those values during
init, so just send the PPAG command again to FW.
