Some mlx5 devices do not support the default advertised maximum frequency
adjustment value for the PTP hardware clock that is set by the driver.
These devices need to be queried when initializing the clock functionality
in order to get the maximum supported frequency adjustment value. This
value can be greater than the minimum supported frequency adjustment across
mlx5 devices (50 million ppb).

Represent scaled ppm as ppb to the device when the value in scaled ppm is
not representable as a 32-bit signed integer. mlx5 devices only support a
32-bit field for the frequency adjustment value in units of either scaled
ppm or ppb.
Since mlx5 devices only support a 32-bit field for the frequency adjustment
value independent of unit used, limit the maximum frequency adjustment to
S32_MAX ppb.

Check if the MTUTC register of the NIC can be modified before attempting to

The top syzbot report for networking (#14 for the entire kernel)
is the queue timeout splat. We kept it around for a long time,
because in real life it provides pretty strong signal that
something is wrong with the driver or the device.
Removing it is also likely to break monitoring for those who
track it as a kernel warning.
Nevertheless, WARN()ings are best suited for catching kernel
programming bugs. If a Tx queue gets starved due to a pause
storm, priority configuration, or other weirdness - that's
obviously a problem, but not a problem we can fix at
the kernel level.
Bite the bullet and convert the WARN() to a print.
Before:
NETDEV WATCHDOG: eni1np1 (netdevsim): transmit queue 0 timed out 1975 ms
WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:525 dev_watchdog+0x39e/0x3b0
[... completely pointless stack trace of a timer follows ...]
Now:
netdevsim netdevsim1 eni1np1: NETDEV WATCHDOG: CPU: 0: transmit queue 0 timed out 1769 ms
Alternatively we could mark the drivers which syzbot has
learned to abuse as "print-instead-of-WARN" selectively.

====================
bnxt_en: TX path improvements
All patches in this patchset are related to improving the TX path.
There are 2 areas of improvements:
1. The TX interrupt logic currently counts the number of TX completions
to determine the number of TX SKBs to free. We now change it so that
the TX completion will now contain the hardware consumer index
information. The driver will keep track of the latest hardware
consumer index from the last TX completion and clean up all TX SKBs
up to that index. This scheme aligns better with future chips and
allows xmit_more code path to be more optimized.
2. The current driver logic requires an additional MSIX for each
additional MQPRIO TX ring. This scheme uses too many MSIX vectors if
the user enables a large number of MQPRIO TCs. We now use a new scheme
that will use the same MSIX for all the MQPRIO TX rings for each
ethtool channel. Each ethtool TX channel can have up to 8 MQPRIO
TX rings and now they all will share the same MSIX.
v2: Rebased
v1 posted on Oct 27 2023 right before the close of net-next:

Now that we use the cumulative consumer index scheme for TX completion,
we don't need to have one TX completion per TX packet in the xmit_more
code path. Set the TX_BD_FLAGS_NO_CMPL flag if xmit_more is true.
Fallback to one interrupt per packet if the ring is filled beyond
bp->tx_wake_thresh.
Also, move the wmb() to bnxt_txr_db_kick(). When xmit_more is true,
we'll skip the bnxt_txr_db_kick() call and there is no need to call
wmb() to sync. the TX BD data.

Up until now, each TX ring always requires a completion ring/NQ/MSIX.
bnxt_trim_rings() and the assignment of bp->cp_nr_rings always make
this assumption. This will no longer be true in the next patches, so
we refactor and add helper functions to determine the proper relationship
between TX rings and the required completion ring/NQ/MSIX. This patch
does not change the 1:1 relationship yet.
Note that on P5 chips, each RX and TX ring still requires a completion
ring. Only the number of NQs has been reduced. We should no longer call
bnxt_trim_rings() to adjust the RX and TX rings on P5 chips. Replace with
simple logic to check that RX + TX < CP and adjust accordingly.
bnxt_check_rings() should call _bnxt_get_max_rings() to get the raw
number of rings instead of bnxt_get_max_rings(). If we are about to
create TCs, bnxt_get_max_rings() would not be able to calculate the max
rings correctly.

Currently, the opaque field in the TX BD is only used for debugging.
The TX completion logic relies on getting one TX completion for each
packet and they always complete in order.
Improve this scheme by putting the producer information (ring index plus
number of BDs for the packet) in the opaque field. This way, we can
handle TX completion processing by looking at the last TX completion
instead of counting the number of completions.
Since we no longer need to count the exact number of completions, we can
optimize xmit_more by disabling TX completion when the xmit_more
condition is true. This will be done in later patches.
This patch is only initializing the opaque field in the TX BD and is
not changing the driver's TX completion logic yet.
