If ring counts are not reset when ring reservation fails,
bnxt_init_dflt_ring_mode() will not be called again to reinitialise
IRQs when open() is called and results in system crash as napi will
also be not initialised. This patch fixes it by resetting the ring
counts.

The allocated ieee_ets structure goes out of scope without being freed,
leaking memory. Appropriate result codes should be returned so that
callers do not rely on invalid data passed by reference.
Also cache the ETS config retrieved from the device so that it doesn't
need to be freed. The balance of the code was clearly written with the
intent of having the results of querying the hardware cached in the
device structure. The commensurate store was evidently missed though.

There is an indexing bug in determining these ethtool priority
counters. Instead of using the queue ID to index, we need to
normalize by modulo 10 to get the index. This index is then used
to obtain the proper CoS queue counter. Rename bp->pri2cos to
bp->pri2cos_idx to make this more clear.

The hardware offloading of the NETIF_F_HW_CSUM and NETIF_F_RXCSUM
features requires the use of Transmit Status Blocks before transmit
frame data and Receive Status Blocks before receive frame data to
carry the checksum information.
Unfortunately, these status blocks are currently only enabled when
the NETIF_F_HW_CSUM feature is enabled. As a result NETIF_F_RXCSUM
will not actually be offloaded to the hardware unless both it and
NETIF_F_HW_CSUM are enabled. Fortunately, that is the default
configuration.
This commit addresses this issue by always enabling the use of
status blocks on both transmit and receive frames. Further, it
replaces the use of a dedicated flag within the driver private
data structure with direct use of the netdev features flags.

As noted in commit 28c2d1a7a0bf ("net: bcmgenet: enable loopback
during UniMAC sw_reset") the UniMAC must be clocked at least 5
cycles while the sw_reset is asserted to ensure a clean reset.
That commit enabled local loopback to provide an Rx clock from the
GENET sourced Tx clk. However, when connected in MII mode the Tx
clk is sourced by the PHY so if an EPHY is not supplying clocks
(e.g. when the link is down) the UniMAC does not receive the
necessary clocks.
This commit extends the sw_reset window until the PHY reports that
the link is up thereby ensuring that the clocks are being provided
to the MAC to produce a clean reset.
One consequence is that if the system attempts to enter a Wake on
LAN suspend state when the PHY link has not been active the MAC
may not have had a chance to initialize cleanly. In this case, we
remove the sw_reset and enable the WoL reception path as normal
with the hope that the PHY will provide the necessary clocks to
drive the WoL blocks if the link becomes active after the system
has entered suspend.

After bnxt_hwrm_do_send_message() was updated to return standard error
codes in a recent commit, a regression in bnxt_flash_package_from_file()

of having 2 variables for different errors.

MTU changes may affect the number of IRQs so we must call
bnxt_close_nic()/bnxt_open_nic() with the irq_re_init parameter
set to true. The reason is that a larger MTU may require
aggregation rings not needed with smaller MTU. We may not be
able to allocate the required number of aggregation rings and
so we reduce the number of channels which will change the number
of IRQs. Without this patch, it may crash eventually in
pci_disable_msix() when the IRQs are not properly unwound.

The current logic that calls pci_disable_device() in __bnxt_close_nic()
during firmware reset is flawed. If firmware is still alive, we're
disabling the device too early, causing some firmware commands to
not reach the firmware.
Fix it by moving the logic to bnxt_reset_close(). If firmware is
in fatal condition, we call pci_disable_device() before we free
any of the rings to prevent DMA corruption of the freed rings. If
firmware is still alive, we call pci_disable_device() after the
last firmware message has been sent.

bnxt_ulp_start() needs to be called before SRIOV is re-enabled after
firmware reset. Re-enabling SRIOV may consume all the resources and
may cause the RDMA driver to fail to get MSIX and other resources.
Fix it by calling bnxt_ulp_start() first before calling
bnxt_reenable_sriov().
We re-arrange the logic so that we call bnxt_ulp_start() and
bnxt_reenable_sriov() in proper sequence in bnxt_fw_reset_task() and
bnxt_open(). The former is the normal coordinated firmware reset sequence
and the latter is firmware reset while the function is down. This new
logic is now more straight forward and will now fix both scenarios.

There are users already and will be more of BITS_TO_BYTES() macro. Move
it to bitops.h for wider use.
In the case of ocfs2 the replacement is identical.
As for bnx2x, there are two places where floor version is used. In the
first case to calculate the amount of structures that can fit one memory
page. In this case obviously the ceiling variant is correct and
original code might have a potential bug, if amount of bits % 8 is not
0. In the second case the macro is used to calculate bytes transmitted
in one microsecond. This will work for all speeds which is multiply of
1Gbps without any change, for the rest new code will give ceiling value,
for instance 100Mbps will give 13 bytes, while old code gives 12 bytes
and the arithmetically correct one is 12.5 bytes. Further the value is
used to setup timer threshold which in any case has its own margins due
to certain resolution. I don't see here an issue with slightly shifting
thresholds for low speed connections, the card is supposed to utilize
highest available rate, which is usually 10Gbps.

Fix bnxt_fltr_match() to match ipv6 source and destination addresses.
The function currently only checks ipv4 addresses and will not work
corrently on ipv6 filters.

The NTUPLE related firmware commands are sent to the wrong firmware
channel, causing all these commands to fail on new firmware that
supports the new firmware channel. Fix it by excluding the 3
NTUPLE firmware commands from the list for the new firmware channel.

We would not be transmitting using the correct SYSTEMPORT transmit queue
during ndo_select_queue() which looks up the internal TX ring map
because while establishing the mapping we would be off by 4, so for
instance, when we populate switch port mappings we would be doing:
switch port 0, queue 0 -> ring index #0
switch port 0, queue 1 -> ring index #1
...
switch port 0, queue 3 -> ring index #3
switch port 1, queue 0 -> ring index #8 (4 + 4 * 1)
...
instead of using ring index #4. This would cause our ndo_select_queue()
to use the fallback queue mechanism which would pick up an incorrect
ring for that switch port. Fix this by using the correct switch queue
number instead of SYSTEMPORT queue number.

When running in XDP mode, pages come from the page pool, and should
be freed back to the same pool or specifically detached. Currently,
when the driver re-initializes, the page pool destruction is delayed
forever since it thinks there are oustanding pages.

This is a straight-forward conversion case for the new function, and
while we're at it, we can remove a null write to skb->next by replacing
it with skb_mark_not_on_list.
