Following patches in the set add support for RX PTP. Rename PTP prefix
from %s/port_ptp/ptp/g to include RX PTP too.
In addition rename indication (used in statistics context) that PTP-SQ
was opened: %s/port_ptp_opened/tx_ptp_opened/g. This will simplify adding
indication that PTP-RQ was opened.

net: ipa: update registers for other versions
This series updates IPA and GSI register definitions to permit more
versions of IPA hardware to be supported. Most of the updates are
informational, updating comments to indicate which IPA versions
support each register and field. But some registers are new and
others are deprecated. In a few cases register fields are laid
out differently, and in these cases the changes are a little more
substantive.
I won't claim the result is 100% correct, but it's close, and should
allow all IPA versions 3.x through 4.x to be supported by the driver.

IPA v4.5 (GSI v2.5) supports a larger set of channel protocols, and
adds an additional field to hold the most-significant bits of the
protocol identifier on a channel.
Add an inline function that encodes the protocol (including the
extra bits for newer versions of IPA), and define some additional
protocols. At this point we still use only GPI protocol.

Each GSI channel has a CNTXT_1 register that encodes the size of its
ring buffer. The size of the field that records that is increased
starting at IPA v4.9. Replace the use of a fixed-size field mask
with a new inline function that encodes that size value.
Similarly, the size of GSI event rings can be larger starting with
IPA v4.9, so create a function to encode that as well.

The main purpose of this is to extend these GSI register definitions
to support additional IPA versions.
This patch makes some minor updates to "gsi_reg.h":
- Define a DB_IN_BYTES field in the channel QOS register
- Add some comments clarifying when certain fields are valid
- Add the definition of GSI_CH_DB_STOP channel command
- Add a couple of blank lines
- Move one comment and indent another
- Delete two unused register definitions at the end.

ethtool: clarify the ethtool FEC interface
Our FEC configuration interface is one of the more confusing.
It also lacks any error checking in the core. This certainly
shows in the varying implementations across the drivers.
Improve the documentation and add most basic checks. Sadly, it's
probably too late now to try to enforce much more uniformity.
Any thoughts & suggestions welcome. Next step is to add netlink
for FEC, then stats.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Reject NONE on set, this mode means device does not support
FEC so it's a little out of place in the set interface.
This should be safe to do - user space ethtool does not allow
the use of NONE on set. A few drivers treat it the same as OFF,
but none use it instead of OFF.
Similarly reject an empty FEC mask. The common user space tool
will not send such requests and most drivers correctly reject
it already.

struct ethtool_fecparam::reserved is never looked at by the core.
Make sure it's actually 0. Unfortunately we can't return an error
because old ethtool doesn't zero-initialize the structure for SET.
On GET we can be more verbose, there are no in tree (ab)users.
Fix up the kdoc on the structure. Remove the mention of FEC
bypass. Seems like a niche thing to configure in the first
