The recent change of the order of the TX and RX FIFOs is not reflected
in the debug info of the FIFO setup. This patch adjust the order and
additionally prints the base address of each FIFO.
Since the mcp251xfd_ring_init() may fail due to wrongly configured
FIFOs, printing of the FIFO setup is moved there. In case of an error
it would not be printed in mcp251xfd_ring_init().

With this patch the usage of the on-chip RAM is checked. In the
current driver the FIFO setup is fixed and always fits into the RAM.
With an upcoming patch series the ring and FIFO setup will be more
dynamic. Although using more RAM than available should not happen, but
add this safety check, just in case.

This patch actually changes the order of the TX and RX FIFOs.
This gives the opportunity to minimize the number of SPI transfers in
the IRQ handler. The read of the IRQ status register and RX FIFO
status registers can be combined into single SPI transfer. If the RX
ring uses FIFO 1, the overall length of the transfer is smaller than
in the original layout, where the RX FIFO comes after the TX FIFO.

This patch improves the initialization of the TX and RX rings. The
initialization functions are now called with pointers to the next free
address (in the on chip RAM) and next free hardware FIFO. The rings
are initialized using these values and the pointers are modified to
point to the next free elements.
This means the order of the mcp251xfd_ring_init_*() functions
specifies the order of the rings in the hardware FIFO. This makes it
possible to change the order of the TX and RX FIFOs, which is done in
the next patch.
This gives the opportunity to minimize the number of SPI transfers in
the IRQ handler. The read of the IRQ status register and RX FIFO
status registers can be combined into single SPI transfer. If the RX
ring uses FIFO 1, the overall length of the transfer is smaller than
in the original layout, where the RX FIFO comes after the TX FIFO.

make use of it
This patch removes the hard coded assumption that the TX ring uses
hardware FIFO 1. This allows the hardware FIFO 1 to be used for RX and
the next free FIFO for TX.
This gives the opportunity to minimize the number of SPI transfers in
the IRQ handler. The read of the IRQ status register and RX FIFO
status registers can be combined into single SPI transfer. If the RX
ring uses FIFO 1, the overall length of the transfer is smaller than
in the original layout, where the RX FIFO comes after the TX FIFO.

The PLL is enabled if the configured clock is less than or equal to 10 times
the max clock frequency.
The device will operate with two different SPI speeds. A slow speed determined
by the clock without the PLL enabled, and a fast speed derived from the
frequency with the PLL enabled.

and error handling
The function mcp251xfd_chip_wait_for_osc_ready() polls the Oscillator
Control Register for the oscillator to get ready.
This is the first register the driver reads from. Reading implausible
values (all bits set or unset) can be caused by the chip starting up
after power on, waking up after sleep, or by the chip not being preset
at all. Add check for implausible register content
mcp251xfd_reg_invalid() to the regmap_read_poll_timeout() loop.
In case of a regmap_read_poll_timeout() returns a fatal error (and not
a timeout), forward it to the caller.
As mcp251xfd_chip_wait_for_osc_ready() will be called after the probe
function has finished, (currently during ifup), move error message
about failed chip detection from there into the probe function.

works on !CONFIG_PM configurations.
This patch simplifies the runtime PM handling in the
mcp251xfd_unregister(). In the CONFIG_PM case, runtime PM has been
enabled in the mcp251xfd_probe() function, so we can disable it here.

OSC register is read
MCP251XFD_REG_OSC is the first register the driver reads from. The
chip may be in deep sleep and the SPI transfer (i.e. the assertion of
the CS) will wake the chip up. This takes about 3ms. The CRC of this
transfer is wrong, or there isn't any chip at all, in this case the
CRC will be wrong, too. The driver ignores the CRC error and returns
the read data to the caller.
To avoid any confusion, this patch changes the
mcp251xfd_regmap_crc_read() function to only ignore the CRC error if
solely the OSC register is read. So when reading more than the OSC
registers at once, CRC errors are not ignored.

to make sure one rcu grace period was observed before freeing
a "struct cgw_job" (which are tiny objects).
This should be converted to call_rcu() to avoid adding delays

====================
Add ethtool support for completion queue event size
After a packet is sent or received by NIC then NIC posts
a completion queue event which consists of transmission status
(like send success or error) and received status(like
pointers to packet fragments). These completion events may
also use a ring similar to rx and tx rings. This patchset
introduces cqe-size ethtool parameter to modify the size
of the completion queue event if NIC hardware has that capability.
A bigger completion queue event can have more receive buffer pointers
inturn NIC can transfer a bigger frame from wire as long as
hardware(MAC) receive frame size limit is not exceeded.
Patch 1 adds support setting/getting cqe-size via
ethtool -G and ethtool -g.
Patch 2 includes octeontx2 driver changes to use
completion queue event size set from ethtool -G.

Offload of ct clear action is just resetting the reg_c register.
It's done by allocating modify hdr resources which is limited.
Doing it multiple times is redundant and wasting modify hdr resources
and if resources depleted the driver will fail offloading the rule.
Ignore redundant ct clear actions after the first one.

Such rules are redundant but allowed and passed to the driver.
The driver does not support offloading such rules so return an error.

For RX TLS device-offloaded packets, the HW spec guarantees checksum
validation for the offloaded packets, but does not define whether the
CQE.checksum field matches the original packet (ciphertext) or
the decrypted one (plaintext). This latitude allows architetctural
improvements between generations of chips, resulting in different decisions
regarding the value type of CQE.checksum.
Hence, for these packets, the device driver should not make use of this CQE
field. Here we block CHECKSUM_COMPLETE usage for RX TLS device-offloaded
packets, and use CHECKSUM_UNNECESSARY instead.
Value of the packet's tcp_hdr.csum is not modified by the HW, and it always
matches the original ciphertext.
