This series provides updates to mlx5 header rewrite feature, from Or Gerlitz.
and three more small updates From maor and eran.
-------
Or says:
Packets belonging to flows which are different by matching may still need
to go through the same header re-writes (e.g set the current routing hop
MACs and issue TTL decrement). To minimize the number of modify header
IDs, we add a cache for header re-write IDs which is keyed by the binary
chain of modify header actions.
The caching is supported for both eswitch and NIC use-cases, where the
actual conversion of the code to use caching comes in separate patches,
one per use-case.
Using a per field mask field, the TC pedit action supports modifying
partial fields. The last patch enables offloading that.

From Maor, update flow table commands layout to the latest HW spec.
From Eran, ethtool connector type reporting updates.

LL2 today is interrupt driven - when tx/rx completion arrives [or any
other indication], qed needs to operate on the connection and pass
the information to the protocol-driver [or internal qed consumer].
Since we have several flavors of ll2 employeed by the driver,
each handler needs to do an if-else to determine the right functionality
to use based on the connection type.
In order to make things more scalable [given that we're going to add
additional types of ll2 flavors] move the infrastrucutre into using
a callback-based approach - the callbacks would be provided as part
of the connection's initialization parameters.

The fact that RTsym table is cached inside nfp_cpp handle is
a relic of old times when nfpcore was a library module. All
the nfp_cpp "caches" are awkward to deal with because of
concurrency and prone to keeping stale information. Make
the run time symbol table be an object read out from the device
and managed by whoever requested it. Since the driver loads
FW at ->probe() and never reloads, we can hold onto the table

Currently the bridge doesn't notify the underlying devices about new
FDBs learned. The FDB sync is placed on the switchdev notifier chain
because devices may potentially learn FDB that are not directly related
to their ports, for example:
1. Mixed SW/HW bridge - FDBs that point to the ASICs external devices
should be offloaded as CPU traps in order to
perform forwarding in slow path.
2. EVPN - Externally learned FDBs for the vtep device.
Notification is sent only about static FDB add/del. This is done due
to fact that currently this is the only scenario supported by switch
drivers.

Using a per field mask field, the TC pedit action supports modifying
partial fields. E.g if using the TC tool, the following example would
make the kernel to only re-write two bytes of the src ip address:
tc filter add dev enp1s0 protocol ip parent ffff: prio 30
flower skip_sw ip_proto udp dst_port 8001
action pedit ex munge ip src set 10.1.0.0 retain 0xffff0000
We add driver support for offload these partial re-writes, by setting
the per FW action offset-in-field and length-from-offset attributes.
The 1st bit set in the mask specifies both the offset and the right
shift to apply on the value such that the 1st bit which needs to be
set will reside in bit 0 of the FW data field.
