mlxsw: Test coverage for DSCP leftover fix

This patch set fixes some global scope pollution issues in the DSCP tests
(in patch #1), and then proceeds (in patch #2) to add a new test for
checking whether, after DSCP prioritization rules are removed from a port,
DSCP rewrites consistently to zero, instead of the last removed rule still
staying in effect.

In case of HE AP-STA link, ieee80211_send_nullfunc() will not
send the QOS NULL packet to check if AP is still associated.

In this case, probe_send_count will be non-zero and
ieee80211_sta_work() will later disassociate the AP, even
though no packet was ever sent.

Fix this by decrementing probe_send_count and not calling
ieee80211_send_nullfunc() in case of HE link, so that we
still wait for some time for the AP beacon to reappear and
don't disconnect right away.

Over time, we really need to get rid of all of our global locking.
One of the things needed is to use parallel_ops. This isn't really
the most important (RTNL is much more important) but OTOH we just
keep adding uses of genl_family_attrbuf() now. Use .parallel_ops to
disallow this.

vsock/virtio: optimizations to increase the throughput

This series tries to increase the throughput of virtio-vsock with slight
changes.
While I was testing the v2 of this series I discovered an huge use of memory,
so I added patch 1 to mitigate this issue. I put it in this series in order
to better track the performance trends.

v5:
- rebased all patches on net-next
- added Stefan's R-b and Michael's A-b

v4: https://patchwork.kernel.org/cover/11047717
v3: https://patchwork.kernel.org/cover/10970145
v2: https://patchwork.kernel.org/cover/10938743
v1: https://patchwork.kernel.org/cover/10885431

Below are the benchmarks step by step. I used iperf3 [1] modified with VSOCK
support. As Michael suggested in the v1, I booted host and guest with 'nosmap'.

A brief description of patches:
- Patches 1:   limit the memory usage with an extra copy for small packets
- Patches 2+3: reduce the number of credit update messages sent to the
               transmitter
- Patches 4+5: allow the host to split packets on multiple buffers and use
               VIRTIO_VSOCK_MAX_PKT_BUF_SIZE as the max packet size allowed

The '%CPU_Guest' is taken inside the VM. I know that it is not the best way,
but it's provided for free from iperf3 and could be an indication.

Since virtio-vsock was introduced, the buffers filled by the host
and pushed to the guest using the vring, are directly queued in
a per-socket list. These buffers are preallocated by the guest
with a fixed size (4 KB).

The maximum amount of memory used by each socket should be
controlled by the credit mechanism.
The default credit available per-socket is 256 KB, but if we use
only 1 byte per packet, the guest can queue up to 262144 of 4 KB
buffers, using up to 1 GB of memory per-socket. In addition, the
guest will continue to fill the vring with new 4 KB free buffers
to avoid starvation of other sockets.

This patch mitigates this issue copying the payload of small
packets (< 128 bytes) into the buffer of last packet queued, in
order to avoid wasting memory.

====================
Finish conversion of skb_frag_t to bio_vec

The recent conversion of skb_frag_t to bio_vec did not include
skb_frag's page_offset.  Add accessor functions for this field,
utilize them, and remove the union, restoring the original structure.

v2:
  - rename accessors
  - follow kdoc conventions

Now that page_offset is referenced through accessors, remove
the union, and use bv_offset.

sctp: clean up __sctp_connect function

This patchset is to factor out some common code for
sctp_sendmsg_new_asoc() and __sctp_connect() into 2
new functioins.

v1->v2:
  - add the patch 1/5 to avoid a slab-out-of-bounds warning.
  - add some code comment for the check change in patch 2/5.
  - remove unused 'addrcnt' as Marcelo noticed in patch 3/5.

In this function factored out from sctp_sendmsg_new_asoc() and
__sctp_connect(), it adds a peer with the other addr into the
asoc after this asoc is created with the 1st addr.

__sctp_connect is doing quit similar things as sctp_sendmsg_new_asoc.
To factor out common functions, this patch is to clean up their code
to make them look more similar:

  1. create the asoc and add a peer with the 1st addr.
  2. add peers with the other addrs into this asoc one by one.

while at it, also remove the unused 'addrcnt'.

Now __sctp_connect() is called by __sctp_setsockopt_connectx() and
sctp_inet_connect(), the latter has done addr_size check with size
of sa_family_t.

In the next patch to clean up __sctp_connect(), we will remove
addr_size check with size of sa_family_t from __sctp_connect()
for the 1st address.

So before doing that, __sctp_setsockopt_connectx() should do
this check first, as sctp_inet_connect() does.

'addr' passed to sctp_transport_init is not always a whole size
of union sctp_addr, like the path:

  sctp_sendmsg() ->
  sctp_sendmsg_new_asoc() ->
  sctp_assoc_add_peer() ->
  sctp_transport_new() -> sctp_transport_init()

In the next patches, we will also pass the address length of data
only to sctp_assoc_add_peer().

So sctp_transport_init() should copy the only available data from
addr to peer->ipaddr, instead of 'peer->ipaddr = *addr' which may
cause slab-out-of-bounds.

rxkad sometimes triggers a warning about oversized stack frames when
building with clang for a 32-bit architecture:

net/rxrpc/rxkad.c:243:12: error: stack frame size of 1088 bytes in function 'rxkad_secure_packet' [-Werror,-Wframe-larger-than=]
net/rxrpc/rxkad.c:501:12: error: stack frame size of 1088 bytes in function 'rxkad_verify_packet' [-Werror,-Wframe-larger-than=]

The problem is the combination of SYNC_SKCIPHER_REQUEST_ON_STACK() in
rxkad_verify_packet()/rxkad_secure_packet() with the relatively large
scatterlist in rxkad_verify_packet_1()/rxkad_secure_packet_encrypt().

The warning does not show up when using gcc, which does not inline the
functions as aggressively, but the problem is still the same.

Allocate the cipher buffers from the slab instead, caching the allocated
packet crypto request memory used for DATA packet crypto in the rxrpc_call
struct.

====================
bnxt_en: Add TPA (GRO_HW and LRO) on 57500 chips.

This patchset adds TPA v2 support on the 57500 chips.  TPA v2 is
different from the legacy TPA scheme on older chips and requires major
refactoring and restructuring of the existing TPA logic.  The main
difference is that the new TPA v2 has on-the-fly aggregation buffer
completions before a TPA packet is completed.  The larger aggregation
ID space also requires a new ID mapping logic to make it more
memory efficient.
