There's no in-tree user for the fs_ops .adjust_link() function, so we
can always use the generic one in fe_enet-main.

Due to the age of the driver and the slow recent activity on it, the code
has taken some layers of dust. Clean the main driver file up so that it
passes checkpatch and also conforms with the net coding style.
Changes include :
- Re-ordering of the variable declarations for RCT
- Fixing the comment styles to either one-line comments, or net-style
comments
- Adding braces around single-statement 'else' clauses
- Aligning function/macro parameters on the opening parenthesis
- Simplifying checks for NULL pointers
- Splitting cascaded assignments into individual assignments
- Fixing some typos
- Fixing whitespace issues
This is a cosmetic change and doesn't introduce any change in behaviour.

In otx2_sqe_add_ext() iplen is used to hold a 16-bit big-endian value,
but it's type is u16, indicating a host byte order integer.
Address this mismatch by changing the type of iplen to __be16.
Flagged by Sparse as:

Recently I noticed that both gcc-14 and clang-18 report that passing
a non-string literal as the format argument of alloc_workqueue()
is potentially insecure.
E.g. clang-18 says:
.../rvu.c:2493:32: warning: format string is not a string literal (potentially insecure) [-Wformat-security]
2493 | mw->mbox_wq = alloc_workqueue(name,
| ^~~~
.../rvu.c:2493:32: note: treat the string as an argument to avoid this
2493 | mw->mbox_wq = alloc_workqueue(name,
| ^
| "%s",
It is always the case where the contents of name is safe to pass as the
format argument. That is, in my understanding, it never contains any
format escape sequences.
But, it seems better to be safe than sorry. And, as a bonus, compiler
output becomes less verbose by addressing this issue as suggested by
clang-18.

Siena hardware does not support custom RSS contexts, but when the
driver was forked from sfc.ko, some of the plumbing for them was
copied across from the common code. Actually trying to use them
would lead to EOPNOTSUPP as the relevant efx_nic_type methods were
not populated.
Remove this dead code from the Siena driver.

Implement the .ndo_open function to set default hardware settings
and initialize the descriptor ring and interrupts. Among them,
when requesting interrupt, because the first group of interrupts
needs to process more events, the overall structure and interrupt
handler will be different from other groups of interrupts, so it
needs to be handled separately. The first set of interrupt handlers
need to handle the interrupt status of RXQ0 and TXQ0, TXQ4~7,
while other groups of interrupt handlers will handle the interrupt
status of RXQ1&TXQ1 or RXQ2&TXQ2 or RXQ3&TXQ3 according to the
interrupt vector.

ice: fix synchronization between .ndo_bpf() and reset
Larysa Zaremba says:
PF reset can be triggered asynchronously, by tx_timeout or by a user. With some
unfortunate timings both ice_vsi_rebuild() and .ndo_bpf will try to access and
modify XDP rings at the same time, causing system crash.
The first patch factors out rtnl-locked code from VSI rebuild code to avoid
deadlock. The following changes lock rebuild and .ndo_bpf() critical sections
with an internal mutex as well and provide complementary fixes.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
ice: do not bring the VSI up, if it was down before the XDP setup

This NIC doesn't have hardware IRQ coalescing. Under high load,
interrupts can adversely affect performance. To mitigate this, enable
software IRQ coalescing by default. On my system this increases receive
throughput with iperf3 from 853 MBit/sec to 934 MBit/s, decreases
interrupts from 69489/sec to 2016/sec, and decreases CPU utilization
from 27% (4x Cortex-A53) to 14%. Latency is not affected (as far as I
can tell).

the return value for a null pointer is redundant, and using IS_ERR is
safe enough.

The mana_set_channels() function requires detaching the mana
driver and reattaching it with changed channel values.
During this operation if the system is low on memory, the reattach
might fail, causing the network device being down.
To avoid this we pre-allocate buffers at the beginning of set operation,
to prevent complete network loss

Add support for group stats for mac. The fbnic_set_counter help preserve
the default values for counters which are not touched by the driver.
The 'reset' flag in 'get_eth_mac_stats' allows to choose between
resetting the counter to recent most value or fetching the aggregated
values of the counter.
The 'fbnic_stat_rd64' read 64b stats counters in an atomic fashion using
read-read-read approach. This allows to isolate cases where counter is
moving too fast making accuracy of the counter questionable.

Add ethtool ops support and enable 'get_drvinfo' for fbnic. The driver
provides firmware version information while the driver name and bus
information is provided by ethtool_get_drvinfo().

These direction specific functions can be ditched in favor of a single
function: sparx5_fdma_reload(), which retrieves the channel id from the
fdma struct instead.

Currently, the driver uses a linked list for storing the tx buffer
addresses. This requires a good amount of extra bookkeeping code. Ditch
the linked list in favor of tx buffers being in the same contiguous
memory space as the DCB's and the DB's. The FDMA library has a helper
for this - so use that.
The tx buffer addresses are now retrieved as an offset into the FDMA
memory space.
