Simplify and fix the version information displayed by the driver.
The new info better relects what is needed to support the hardware.
Prev:
Version: 4.8.0, Pipeline 22169 0x4001, Rev 0, Bond 5, CSR 311, IRQ 2
New:
Version: 4.8.0, Id: 0x4001 Hw Rev: 5 OTP Config Select: 15
- Remove pipeline, CSR and IRQ because version x.y.z already incorporates
this information.
- Remove bond number because it is not used.
- Remove rev number because register was not implemented, always 0
- Add HW Rev ID register to replace rev number
- Add OTP config select to show the user configuration chosen by
the configurable GPIO pins on start-up

Make sure the NIC drops packets that are larger than the
specified MTU.
The front end of the NIC will accept packets larger than MTU and
will copy all the data it can to fill up the driver's posted
buffers - if the buffers are not long enough the packet will
then get dropped. With the Rx SG buffers allocagted as full
pages, we are currently setting up more space than MTU size
available and end up receiving some packets that are larger
than MTU, up to the size of buffers posted. To be sure the
NIC doesn't waste our time with oversized packets we need to
lie a little in the SG descriptor about how long is the last
SG element.
At dealloc time, we know the allocation was a page, so the
deallocation doesn't care about what length we put in the
descriptor.

Until now it was possible to pass a packet to a single destination such
as vport or flow table. With the new support if multiple vports or multiple
tables are provided as destinations, fs_dr will create a multiple
destination table action, this action should replace other destination
actions provided to mlx5dr_create_rule.
Each vport destination can be provided with a reformat actions which
will be done before forwarding the packet to the vport.

A multiple destination table action allows HW packet duplication
to multiple destinations, this is useful for multicast or mirroring
traffic for debug. Duplicating is done using a FW flow table with
multiple destinations.

In below sequence, a EQE entry arrives for a CQ which is on the path of
being destroyed.
cpu-0 cpu-1
------ -----
mlx5_core_destroy_cq() mlx5_eq_comp_int()
mlx5_eq_del_cq() [..]
radix_tree_delete() [..]
[..] mlx5_eq_cq_get() /* Didn't find CQ is
* a valid case.
*/
/* destroy CQ in hw */
mlx5_cmd_exec()
This is still a valid scenario and correct delete CQ sequence, as
mirror of the CQ create sequence.
Hence, suppress the non harmful debug message from warn to debug level.
Keep the debug log message rate limited because user application can
trigger it repeatedly.

Currently the max number of channels is limited to 64, which is half of
the indirection table size to allow some flexibility. But on servers
with more than 64 cores, users may want to utilize more queues.
This patch increases the advertised max number of channels to 128 by
changing the ratio between channels and indirection table slots to 1:1.
At the same time, the driver still enable no more than 64 channels at
loading. Users can change it by ethtool afterwards.

In some configurations, gcc tries too hard to optimize this code:
drivers/net/ethernet/mellanox/mlx5/core/en_stats.c: In function 'mlx5e_grp_sw_update_stats':
drivers/net/ethernet/mellanox/mlx5/core/en_stats.c:302:1: error: the frame size of 1336 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
As was stated in the bug report, the reason is that gcc runs into a corner
case in the register allocator that is rather hard to fix in a good way.
As there is an easy way to work around it, just add a comment and the
barrier that stops gcc from trying to overoptimize the function.

This adds support for timestamping packets being transmitted.
Based on the code from i210. The basic differences is that i225 has 4
registers to store the transmit timestamps (i210 has one). Right now,
we only support retrieving from one register, support for using the
other registers will be added later.
