The ACL flex action will have to know if it is in ingress or egress,
so it can use correct trap ID. Pass the ingress indication down to it.

Action drop is going to be tracked by two separate traps, one for
ingress and one for egress. Prepare for it and disallow the possibility
to have drop action in blocks which are bound to both ingress and
egress.

Introduce a new macro MLXSW_RXL_DIS that allows to register listeners
as disabled. That allows that from now on, the "action" can be
understood always as "enabled action" and "unreg_action" as "disabled

Currently it does not really matter if it is set to DISCARD or
SET_FW_DEFAULT because it is set only during unregister of the listener.
The unreg_action is going to be used for disabling the listener too, so
change to SET_FW_DEFAULT and ensure the HW is going to behave correctly.

Clean driver, module and FW versions

Change log:
 v1:
  * Split all FW cleanups patches to separate patches
  * Fixed commit message
  * Deleted odd DRV_RELDATE
  * Added everyone from MAINTAINERS file
 v0: https://lore.kernel.org/netdev/20200220145855.255704-1-leon@kernel.org

This is first patchset to netdev (already sent RDMA [1] and arch/um [2])
in attempt to unify the version management for in-tree kernel code.
The patches follow already accepted ethtool change [3] to set as
a default linux kernel version.

It allows us to remove driver version and present to the users unified
picture of driver version, which is similar to default MODULE_VERSION().

As part of this series, I deleted various creative attempts to mark
absence of FW. There is no need to set "N/A" in ethtool ->fw_version
field and it is enough to do not set it.

1.
The code is compile tested and passes 0-day kbuild.
2.
The proposed changes are based on commit:
  2bb07f4e ("tc-testing: updated tdc tests for basic filter")
3.
WIP branch is [4].
