Jiri says:
Currently the matchall and flower are handled by registering separate
callbacks in mlxsw. That leads to faulty indication "in_hw_count 2" in
filter show command for every inserted flower filter. That happens
because matchall callback just blindly returns 0 for it and it is
wrongly accounted for as "the offloader".
I inspected different ways to fix this problem. The only clean solution
is to rework handling of matchall in mlxsw a bit. The driver newely
registers one callback for bound block which is called for both matchall
and flower filter insertions.
On the way, iron out the matchall code a bit, push it into a separate
file etc.

The struct is defined in the header, no need to have the helpers
in the c file. Move the helpers to the header.

The acl_block structure is going to be used for non-acl case - matchall
offload. So rename it accordingly.

From: Jiri Pirko <jiri@mellanox.com>
The code around flow_block is currently mixed in spectrum_acl.c.
However, as it really does not directly relate to ACL part only,
push the bits into a separate file.

From: Jiri Pirko <jiri@mellanox.com>
Similar to flower, have matchall related code in a separate file.
Do some small renaming on the way (consistent "mall" prefixes,
dropped "_tc_", dropped "_port_" where suitable).

Instead of having it in mirror_entry structure, move it to mall_entry
and set it during rule insertion.

From: Jiri Pirko <jiri@mellanox.com>
Currently, only the psample_group is accessed using RCU on RX path.
However, it is possible (unlikely) that other sample values get change
during RX processing. Fix this by having the port->sample struct
accessed as RCU pointer, containing all sample values including
psample_group pointer. That avoids extra alloc per-port, copying the
values and the race condition described above.

Currently there are two callbacks registered: one for matchall,
one for flower. This causes the user to see "in_hw_count 2" in TC filter
dump. Because of this and also as a preparation for future matchall
offload for rules equivalent to flower-all-match, move the processing of
shared block into matchall.c. Leave only one cb for mlxsw driver
per-block.
