The NVM version and Option ROM version information is stored within the
struct ice_nvm_ver_info structure. The data for the NVM is stored as
a 2byte value with the major and minor versions each using one byte from
the field. The Option ROM is stored as a 4byte value that contains
a major, build, and patch number.
Modify the code to immediately extract the version values and store them
in a new struct ice_orom_info. Remove the now unnecessary
ice_get_nvm_version function.
Update ice_ethtool.c to use the new fields directly from the structured
data.
This reduces complexity of the code that prints these versions in
ice_ethtool.c
Update the macro definitions and variable names to use the term "orom"
instead of "oem" for the Option ROM version. This helps increase the

"fallthrough" comments are used in switch case statements to explicitly
indicate the code is intended to fall through to the following statement.
Different variants of "fallthough" are acceptable, e.g. "fall through",
"fallthrough", "Fall-through". The GCC compiler has an optional warning
(-Wimplicit-fallthrough[=n]) to warn when such a comment is not present;
the default version of which is enabled when compiling the Linux kernel.
There have been recent discussions in kernel mailing lists regarding
replacing non-standardized "fallthrough" comments with the pseudo-reserved
word 'fallthrough' which will be defined as __attribute__ ((fallthrough))
for versions of gcc that support it (i.e. gcc 7 and newer) or as a nop
for versions that do not. Replace "fallthrough" comments with fallthrough

The ice_init_all_ctrlq and ice_shutdown_all_ctrlq functions create and
destroy the locks used to protect the send and receive process of each
control queue.
This is problematic, as the driver may use these functions to shutdown
and re-initialize the control queues at run time. For example, it may do
this in response to a device reset.
If the driver failed to recover from a reset, it might leave the control
queues offline. In this case, the locks will no longer be initialized.
A later call to ice_sq_send_cmd will then attempt to acquire a lock that
has been destroyed.
It is incorrect behavior to access a lock that has been destroyed.
Indeed, ice_aq_send_cmd already tries to avoid accessing an offline
control queue, but the check occurs inside the lock.
The root of the problem is that the locks are destroyed at run time.
Modify ice_init_all_ctrlq and ice_shutdown_all_ctrlq such that they no
longer create or destroy the locks.
Introduce new functions, ice_create_all_ctrlq and ice_destroy_all_ctrlq.
Call these functions in ice_init_hw and ice_deinit_hw.
Now, the control queue locks will remain valid for the life of the
driver, and will not be destroyed until the driver unloads.
This also allows removing a duplicate check of the sq.count and
rq.count values when shutting down the controlqs. The ice_shutdown_ctrlq
function already checks this value under the lock. Previously
commit dec64ff10e ("ice: use [sr]q.count when checking if queue is
initialized") needed this check to happen outside the lock, because it
prevented duplicate attempts at destroying the locks.
The driver may now safely use ice_init_all_ctrlq and
ice_shutdown_all_ctrlq while handling reset events, without causing the
locks to be invalid.

Currently, ice_stat_update32 and ice_stat_update40 will limit the
value of the software statistic to 32 or 40 bits wide, depending on
which register is being read.
This means that if a driver is running for a long time, the displayed
software register values will roll over to zero at 40 bits or 32 bits.
This occurs because the functions directly assign the difference between
the previous value and current value of the hardware statistic.
Instead, add this value to the current software statistic, and then
update the previous value.
In this way, each time ice_stat_update40 or ice_stat_update32 are
called, they will increment the software tracking value by the
difference of the hardware register from its last read. The software
tracking value will correctly count up until it overflows a u64.
The only requirement is that the ice_stat_update functions be called at
least once each time the hardware register overflows.
While we're fixing ice_stat_update40, modify it to use rd64 instead of
two calls to rd32. Additionally, drop the now unnecessary hireg
function parameter.

This patch adds a new function ice_pf_dcb_cfg (and related helpers)
which applies the DCB configuration obtained from the firmware. As
part of this, VSIs/netdevs are updated with traffic class information.
This patch requires a bit of a refactor of existing code.
1. For a MIB change event, the associated VSI is closed and brought up
again. The gap between closing and opening the VSI can cause a race
condition. Fix this by grabbing the rtnl_lock prior to closing the
VSI and then only free it after re-opening the VSI during a MIB
change event.
2. ice_sched_query_elem is used in ice_sched.c and with this patch, in
ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is
unset. This results in namespace warnings (ice_sched.o: Externally
defined symbols with no external references) when CONFIG_DCB is unset.
To avoid this move ice_sched_query_elem from ice_sched.c to
ice_common.c.
