Implement support for action sample when used with a flower classifier
by implementing the required sampler_add() / sampler_del() callbacks and
registering an Rx listener for the sampled packets.
The sampler_add() callback returns an error for Spectrum-1 as the
functionality is not supported. In Spectrum-{2,3} the callback creates a
mirroring agent towards the CPU. The agent's identifier is used by the
policy engine code to mirror towards the CPU with probability.
The Rx listener for the sampled packet is registered with the 'policy
engine' mirroring reason and passes trapped packets to the psample
module after looking up their parameters (e.g., sampling group).

Add core functionality required to support mirror sampler action in the
policy engine. The switch driver (e.g., 'mlxsw_spectrum') is required to
implement the sampler_add() / sampler_del() callbacks that perform the
necessary configuration before the sampler action can be installed. The
next patch will implement it for Spectrum-{2,3}, while Spectrum-1 will
return an error, given it is not supported.

Allow user space to install a matchall classifier with sample action on
egress. This is only supported on Spectrum-2 onwards, so Spectrum-1 will
continue to return an error.
Programming the hardware to sample on egress is identical to ingress
sampling with the sole change of using a different sampling trigger.
Upon receiving a sampled packet, the sampling trigger (ingress vs.
egress) will be encoded in the mirroring reason in the Completion Queue
Element (CQE). The mirroring reason is used to lookup the sampling
parameters (e.g., psample group) which are passed to the psample module.
Note that locally generated packets that are sampled are simply
consumed. This is done for several reasons.
First, such packets do not have an ingress netdev given that their Rx
local port is the CPU port. This breaks several basic assumptions.
Second, sampling using the same interface (tc), but with flower
classifier will not result in locally generated packets being sampled
given that such packets are not subject to the policy engine.
Third, realistically, this is not a big deal given that the vast
majority of the packets being transmitted through the port are not
locally generated packets.
Fourth, if such packets do need to be sampled, they can be sampled with
a 'skip_hw' filter and reported to the same sampling group as the data
path packets. The software sampling rate can also be adjusted to fit the
rate of the locally generated packets which is much lower than the rate
of the data path traffic.

Currently, mlxsw supports a single sampling trigger type (i.e., received
packet). When sampling is configured on an ingress port, the sampling
parameters (e.g., pointer to the psample group) are stored as an
attribute of the port, so that they could be passed to
psample_sample_packet() when a sampled packet is trapped to the CPU.
Subsequent patches are going to add more types of sampling triggers,
making it difficult to maintain the current scheme.
Instead, store all the active sampling triggers with their associated
parameters in a hash table. That way, more trigger types can be easily
added.
The next patch will flip mlxsw to use the hash table instead of the
current scheme.

Push some sampling checks to the per-ASIC operations, as they are no
longer relevant for all ASICs.
The sampling rate validation against the MPSC maximum rate is only
relevant for Spectrum-1, as Spectrum-2 and later ASICs no longer use
MPSC register for sampling.
The ingress / egress validation is pushed down to the per-ASIC
operations since subsequent patches are going to remove it for

There are two "netif_running" checks in this driver. One is in
"lapbeth_xmit" and the other is in "lapbeth_rcv". They serve to make
sure that the LAPB APIs called in these functions are called before
"lapb_unregister" is called by the "ndo_stop" function.
However, these "netif_running" checks are unreliable, because it's
possible that immediately after "netif_running" returns true, "ndo_stop"
is called (which causes "lapb_unregister" to be called).
This patch adds locking to make sure "lapbeth_xmit" and "lapbeth_rcv" can
reliably check and ensure the netif is running while doing their work.

One issue with the original TSO code was that it was working too
hard to deal with skb layouts that were never going to show up,
such as an skb->data that was longer than a single descriptor's
length. The other issue was trying to arrange the fragment dma
mapping at the same time as figuring out the descriptors needed.
There was just too much going on at the same time.
Now we do the dma mapping first, which sets up the buffers with
skb->data in buf[0] and the remaining frags in buf[1..n-1].
Next we spread the bufs across the descriptors needed, where
each descriptor gets up to mss number of bytes.

Replace the use of C bit-fields in the rmnet_map_ul_csum_header
structure with a single two-byte (big endian) structure member,
and use masks to encode or get values within it. The content of
these fields can be accessed using simple bitwise AND and OR
operations on the (host byte order) value of the new structure
member.
Previously rmnet_map_ipv4_ul_csum_header() would update C bit-field
values in host byte order, then forcibly fix their byte order using
a combination of byte swap operations and types.
Instead, just compute the value that needs to go into the new
structure member and save it with a simple byte-order conversion.
Make similar simplifications in rmnet_map_ipv6_ul_csum_header().
Finally, in rmnet_map_checksum_uplink_packet() a set of assignments
zeroes every field in the upload checksum header. Replace that with

The actual layout of bits defined in C bit-fields (e.g. int foo : 3)
is implementation-defined. Structures defined in <linux/if_rmnet.h>
address this by specifying all bit-fields twice, to cover two
possible layouts.
I think this pattern is repetitive and noisy, and I find the whole
notion of compiler "bitfield endianness" to be non-intuitive.
Stop using C bit-fields for the command/data flag and the pad length
fields in the rmnet_map structure, and define a single-byte flags
field instead. Define a mask for the single-bit "command" flag,
and another mask for the encoded pad length. The content of both
fields can be accessed using a simple bitwise AND operation.

The following macros, defined in "rmnet_map.h", assume a socket
buffer is provided as an argument without any real indication this
is the case.
RMNET_MAP_GET_MUX_ID()
RMNET_MAP_GET_CD_BIT()
RMNET_MAP_GET_PAD()
RMNET_MAP_GET_CMD_START()
RMNET_MAP_GET_LENGTH()
What they hide is pretty trivial accessing of fields in a structure,
and it's much clearer to see this if we do these accesses directly.
So rather than using these accessor macros, assign a local
variable of the map header pointer type to the socket buffer data
pointer, and derereference that pointer variable.
In "rmnet_map_data.c", use sizeof(object) rather than sizeof(type)
in one spot. Also, there's no need to byte swap 0; it's all zeros
irrespective of endianness.

This patch introduces the .prepare() for e1000e so that if the NIC is runtime
suspended the subsequent suspend/resume hooks will be skipped so as to speed
up the s2ram. The pm core will check whether the NIC is a wake up device so
there's no need to check it again in .prepare(). DPM_FLAG_SMART_PREPARE flag
should be set during probe to ask the pci subsystem to honor the driver's
prepare() result. Besides, the NIC remains runtime suspended after resumed
from s2ram as there is no need to resume it.
