This socket-lookup path did not pass along the skb in question
in my original BPF-based socket selection patch. The skb in the
udpN_lib_lookup2 path can be used for BPF-based socket selection just
like it is in the 'traditional' udpN_lib_lookup path.
udpN_lib_lookup2 kicks in when there are greater than 10 sockets in
the same hlist slot. Coincidentally, I chose 10 sockets per
reuseport group in my functional test, so the lookup2 path was not
excersised. This adds an additional set of tests with 20 sockets.

During initialization, when creating the send descriptor queues (SDQs),
we specify the CPU egress traffic class of each SDQ. The maximum number
of classes of this type is different in the two ASICs supported by this
PCI driver.
New firmware versions check this value is set correctly, which causes
errors on the Spectrum ASIC, as its max exposed egress traffic class is
lower than 7.
Solve this by setting this field to 3, which is an acceptable value for
both ASICs.
Note that we currently do not expose the QoS capabilities of the ASICs,
so setting this to an hardcoded value is OK for now.

Add a PHC support to the mlx5_en driver. Use reader/writer spinlocks to
protect the timecounter since every packet received needs to call
timecounter_cycle2time() when timestamping is enabled. This can become
a performance bottleneck with RSS and multiple receive queues if normal
spinlocks are used.
The driver has been tested with both Documentation/ptp/testptp and the
linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox

Include a struct sock_reuseport instance when a UDP socket binds to
a specific address for the first time with the reuseport flag set.
When selecting a socket for an incoming UDP packet, use the information
available in sock_reuseport if present.
This required adding an additional field to the UDP source address
equality function to differentiate between exact and wildcard matches.
The original use case allowed wildcard matches when checking for
existing port uses during bind. The new use case of adding a socket
to a reuseport group requires exact address matching.
Performance test (using a machine with 2 CPU sockets and a total of
48 cores): Create reuseport groups of varying size. Use one socket
from this group per user thread (pinning each thread to a different
core) calling recvmmsg in a tight loop. Record number of messages
received per second while saturating a 10G link.
10 sockets: 18% increase (~2.8M -> 3.3M pkts/s)
20 sockets: 14% increase (~2.9M -> 3.3M pkts/s)
40 sockets: 13% increase (~3.0M -> 3.4M pkts/s)

struct sock_reuseport is an optional shared structure referenced by each
socket belonging to a reuseport group. When a socket is bound to an
address/port not yet in use and the reuseport flag has been set, the
structure will be allocated and attached to the newly bound socket.
When subsequent calls to bind are made for the same address/port, the
shared structure will be updated to include the new socket and the
newly bound socket will reference the group structure.
Usually, when an incoming packet was destined for a reuseport group,
all sockets in the same group needed to be considered before a
dispatching decision was made. With this structure, an appropriate
socket can be found after looking up just one socket in the group.
This shared structure will also allow for more complicated decisions to
be made when selecting a socket (eg a BPF filter).
This work is based off a similar implementation written by
Ying Cai <ycai@google.com> for implementing policy-based reuseport
selection.

ARM allmodconfig fails because of the addition of the FMAN driver:

drivers/built-in.o: In function `start':
binder.c:(.text+0x176078): undefined reference to `phy_start'
The reason is that the driver uses PHYLIB, but that is a loadable
module here, and fman itself is built-in.
This patch makes it possible to configure fman as a module as well
so we don't change the status of PHYLIB in an allmodconfig kernel,
and it adds a 'select PHYLIB' statement to ensure that phylib is
always built-in when fman is.
The driver uses "builtin_platform_driver(fman_driver);", which means
it cannot be unloaded, but it's still possible to have it as a loadable
module that gets loaded once and never removed.

Moving the caller of iptunnel_xmit_stats causes a build error in

The reason is that the iptunnel_xmit_stats definition is hidden
inside #ifdef CONFIG_INET but the caller is not. We can change
one or the other to fix it, and this patch adds a second #ifdef
around ip6tunnel_xmit() to avoid seeing the invalid call.

Backport of this upstream commit into stable kernels :
89c22d8c3b27 ("net: Fix skb csum races when peeking")
exposed a bug in udp stack vs MSG_PEEK support, when user provides
a buffer smaller than skb payload.
In this case,
skb_copy_and_csum_datagram_iovec(skb, sizeof(struct udphdr),
msg->msg_iov);
returns -EFAULT.
This bug does not happen in upstream kernels since Al Viro did a great
job to replace this into :
skb_copy_and_csum_datagram_msg(skb, sizeof(struct udphdr), msg);
This variant is safe vs short buffers.
For the time being, instead reverting Herbert Xu patch and add back
skb->ip_summed invalid changes, simply store the result of
udp_lib_checksum_complete() so that we avoid computing the checksum a
second time, and avoid the problematic
skb_copy_and_csum_datagram_iovec() call.
This patch can be applied on recent kernels as it avoids a double
checksumming, then backported to stable kernels as a bug fix.

In order to support dedicated or shared completion rings, the ring

completion ring index.
2. rx rings 0 to n will be mapped to completion rings 0 to n.
3. If tx and rx rings share completion rings, then tx rings 0 to m will
be mapped to completion rings 0 to m.
4. If tx and rx rings use dedicated completion rings, then tx rings 0 to
m will be mapped to completion rings n + 1 to n + m.
5. Each tx or rx ring will use the corresponding completion ring index
for doorbell mapping and MSIX mapping.

Currently, an rx and a tx ring are always paired with a completion ring.
We want to restructure it so that it is possible to have a dedicated
completion ring for tx or rx only.
The bnxt hardware uses a completion ring for rx and tx events. The driver
has to process the completion ring entries sequentially for the rx and tx
events. Using a dedicated completion ring for rx only or tx only has these
benefits:
1. A burst of rx packets can cause delay in processing tx events if the
completion ring is shared. If tx queue is stopped by BQL, this can cause
delay in re-starting the tx queue.
2. A completion ring is sized according to the rx and tx ring size rounded
up to the nearest power of 2. When the completion ring is shared, it is
sized by adding the rx and tx ring sizes and then rounded to the next power
of 2, often with a lot of wasted space.
3. Using dedicated completion ring, we can adjust the tx and rx coalescing
parameters independently for rx and tx.
The first step is to separate the rx and tx ring structures from the
bnxt_napi struct.
In this patch, an rx ring and a tx ring will point to the same bnxt_napi
struct to share the same completion ring. No change in ring assignment
and mapping yet.

Enable the FW Logger to work over the SDIO interface in addition to over UART
interface. In the new design we use fw internal memory instead of packet ram
that was used in older (wl12xx) design. This change reduces the impact on TP
and stability.
A new event was added to notify fw logger is ready for reading. Dynamic
configuration to debugfs was added as well.
