This driver currently prints the link status using four separate
printk calls, which these days gets presented to the user as four
distinct messages, not exactly ideal:
[ 32.582778] eth0: Link is up using
[ 32.582828] internal
[ 32.582837] transceiver at
[ 32.582888] 100Mb/s, Full Duplex.
Restructure the display_link_mode function to use a single netdev_info
call to present all this information as a single message, which is much
nicer:
[ 33.640143] hme 0000:00:01.1 eth0: Link is up using internal transceiver at 100Mb/s, Full Duplex.
The display_forced_link_mode function has a similar structure, so adjust
it in a similar fashion.

A warning is triggered by commit 66e4c8d95008 ("net: warn if transport
header was not set"). The warning is harmless, because the value from
skb_transport_offset() is only used for skb_is_gso() is true or the

In few error cases MAC(CGX/RPM) block is having 0 lmacs.
AF driver uses MAC block with lmac pair to get firmware

associated with MAC block.

uses correct MAC block and LMAC pair for firmware communication and
define new LMAC_AF_ERROR types for command timeout etc.

Define bridge MDB entry (software entry):
- entry that get's created upon receiving MDB management events
(create/delete), that inherently defines a software entry,
which can be enabled (offloaded to the HW) or disabled (removed
from HW).
This separation is done to achieve a better highlevel
management of HW resources - software MDB entry could exist,
while it's not necessarily should be configured on the HW.
For example: by default, the Linux behavior would not replicate
multicast traffic to multicast group members if there's no
active multicast router and thus - no actual multicast traffic
can be received/sent. So, until multicast router appears on the
system no HW configuration should be applied, although SW MDB entries
should be tracked.
Another example would be altering state of 'multicast enabled' on
the bridge: MC_DISABLED should invoke disabling / clearing multicast
groups of specified bridge on the HW, yet upon receiving 'multicast
enabled' event, driver should reconfigure any existing software MDB
groups on the HW.
Keeping track of software MDB entries in such way makes it possible
to properly react on such events.
Define bridge MDB port entry (software entry):
- entry that helps keeping track (on software - driver - level) of which
bridge mebemer interface joined any give MDB group;

When building with Clang we encounter these warnings:
| drivers/net/ethernet/qlogic/qed/qed_dev.c:416:30: error: format

| specifies type 'char' but the argument has type 'int' [-Werror,-Wformat]
| p_llh_info->num_ppfid - 1);
For the first warning, `i` is a u32 which is much wider than the format
specifier `%hhd` describes. This results in a loss of bits after 2^7.
The second warning involves implicit integer promotion as the resulting
type of addition cannot be smaller than an int.
example:
``
uint8_t a = 4, b = 7;
int size = sizeof(a + b - 1);
printf("%d\n", size);
// output: 4
```
See more:
(https://wiki.sei.cmu.edu/confluence/display/c/INT02-C.+Understand+integer+conversion+rules)
"Integer types smaller than int are promoted when an operation is
performed on them. If all values of the original type can be represented
as an int, the value of the smaller type is converted to an int;
otherwise, it is converted to an unsigned int."

The upper 32-bit PHC register is not latched when reading the lower
32-bit PHC register. Current code leaves a small window where we may
not read correct higher order bits if the lower order bits are just about
to wrap around.
This patch fixes this by reading higher order bits twice and makes
sure that final value is correctly paired with its lower 32 bits.

bnxt_reinit_after_abort() is called during ifup when a previous
FW reset sequence has aborted or a previous ifup has failed after
detecting FW reset. In all cases, it is safe to assume that a
previous FW reset has completed and the driver may not have fully
reinitialized.
Prior to this patch, it is assumed that the
FUNC_DRV_IF_CHANGE_RESP_FLAGS_HOT_FW_RESET_DONE flag will always be
set by the firmware in bnxt_hwrm_if_change(). This may not be true if
the driver has already attempted to register with the firmware. The
firmware may not set the RESET_DONE flag again after the driver has
registered, assuming that the driver has seen the flag already.
Fix it to always go through the FW reset initialization path if
the BNXT_STATE_FW_RESET_DET flag is set. This flag is always set
by the driver after successfully going through bnxt_reinit_after_abort().

When creating a snapshot of the NVM the driver needs to read the entire
contents from the NVM and store it. The NVM reads are protected by a lock
that is shared between the driver and the firmware.
If the driver takes too long to read the entire NVM (which can happen on
some systems) then the firmware could reclaim the lock and cause subsequent
reads from the driver to fail.
We could fix this by increasing the timeout that we pass to the firmware,
but we could end up in the same situation again if the system is slow.
Instead have the driver break the reading of the NVM into blocks that are
small enough that we have confidence that the read will complete within the
timeout time, but large enough not to cause significant AQ overhead.

If remove or probe were called by module init or module cleanup flows,

it is called by attach/detach or register/unregister flow and we can

pfc->pfc_cap , pfc->pfc_cn, pfc->mbc are all of type `u8` while pfc->delay is

Moreover, C11 6.3.1.1 states:
(https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf) `If an int
can represent all values of the original type ..., the value is
converted to an int; otherwise, it is converted to an unsigned int.
These are called the integer promotions.`

Use devm_bitmap_zalloc() instead of hand-writing them.
It is less verbose and it improves the semantic.

NAPI poll() function may be passed a budget value of zero, i.e. during
netpoll, which isn't NAPI context.
Therefore, napi_consume_skb() must be given budget value instead of
!force to truly discern netpoll-like scenarios.
Fixes: c63c615e22eb ("bcm63xx_enet: switch to napi_build_skb() to reuse skbuff_heads")

NPC exact match table can support more entries than RPM
dmac filters. This requires field size of DMAC filter count
and index to be increased.

These functions are wrappers for mac add/addr/del/update in
exact match table. These will be invoked from mbox handler routines
if exact matct table is supported and enabled.

Exact match table modification requires wider fields as it has
more number of slots to fill in. Modifying an entry in exact match
table may cause hash collision and may be required to delete entry
from 4-way 2K table and add to fully associative 32 entry CAM table.

NPC exact match table installs drop on hit rules in
NPC mcam for each channel. This rule has broadcast and multicast
bits cleared. Exact match bit cleared and channel bits
set. If exact match table hit bit is 0, corresponding NPC mcam
drop rule will be hit for the packet and will be dropped.

CN10KB silicon supports Exact match feature. This feature can be disabled
through devlink configuration. Devlink command fails if DMAC filter rules
are already present. Once disabled, legacy RPM based DMAC filters will be
configured.
