Currently when hns3 driver configures the tm shaper to limit
bandwidth below 20Mbit using the parameters calculated by
hclge_shaper_para_calc(), the actual bandwidth limited by tm
hardware module is not accurate enough, for example, 1.28 Mbit
when the user is configuring 1 Mbit.
This patch adjusts the ir_calc to be closer to ir, and
always calculate the ir_b parameter when user is configuring
a small bandwidth. Also, removes an unnecessary parenthesis
when calculating denominator.

After setting new channel num, it needs free old ring memory and

new ring memory fail, the ring may initialize fail. To make sure
the network interface can work normally, driver should revert the

The firmware reset and loading policies can be controlled with the
combination of three hwinfo keys, 'abi_drv_reset', 'abi_drv_load_ifc'
and 'app_fw_from_flash'.
'app_fw_from_flash' defines which firmware should take precedence,
'Disk', 'Flash' or the 'Preferred' firmware. When 'Preferred'
is selected, the management firmware makes the decision on which
firmware will be loaded by comparing versions of the flash firmware
and the host supplied firmware.
'abi_drv_reset' defines when the driver should reset the firmware when
the driver is probed, either 'Disk' if firmware was found on disk,
'Always' reset or 'Never' reset. Note that the device is always reset
on driver unload if firmware was loaded when the driver was probed.
'abi_drv_load_ifc' defines a list of PF devices allowed to load FW on
the device.
Furthermore, we limit the cases to where the driver will unload firmware
again when the driver is removed to only when firmware was loaded by the
driver and only if this particular device was the only one that could
have loaded firmware. This is needed to avoid firmware being removed
while in use on multi-host platforms.

There are cases where we want to read a hwinfo entry from the NFP, and
if it doesn't exist, use a default value instead.
To support this, we must silence warning/error messages when the hwinfo
entry doesn't exist since this is a valid use case. The NSP command
structure provides the ability to silence command errors, in which case
the caller should log any command errors appropriately. Protocol errors
are unaffected by this.

In Xen environment, if Xen-swiotlb is enabled, ixgbe driver
could possibly allocate a page, DMA memory buffer, for the first
fragment which is not suitable for Xen-swiotlb to do DMA operations.
Xen-swiotlb have to internally allocate another page for doing DMA
operations. This mechanism requires syncing the data from the internal
page to the page which ixgbe sends to upper network stack. However,
since commit f3213d932173 ("ixgbe: Update driver to make use of DMA
attributes in Rx path"), the unmap operation is performed with
DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed.
Since the sync isn't performed, the upper network stack could receive
a incomplete network packet. By incomplete, it means the linear data
on the first fragment(between skb->head and skb->end) is invalid. So
we have to copy the data from the internal xen-swiotlb page to the page
which ixgbe sends to upper network stack through the sync operation.
More details from Alexander Duyck:
Specifically since we are mapping the frame with
DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result
a sync is not performed on an unmap and must be done manually as we
skipped it for the first frag. As such we need to always sync before
possibly performing a page unmap operation.

Since commit
'5098850c9b9b ("i40e/i40evf: i40e_register.h updates")'
it is no longer possible to trigger an EMP Reset from debugfs, but it's
possible to request it either way, to end up with a bad reset request:
echo empr > /sys/kernel/debug/i40e/0002\:01\:00.1/command
i40e 0002:01:00.1: debugfs: forcing EMPR
i40e 0002:01:00.1: bad reset request 0x00010000

There are several uses of hw_dbg in the code, producing no output. This
patch implements it using dev_debug.
Initially the intention was to implement it using netdev_dbg, analogously
to what is done in ixgbe for instance. That approach was avoided due to
some early usages of hw_dbg, like i40e_pf_reset, before the VSI structure
initialization causing NULL pointer dereference during the driver probe if
the debug messages were turned on as soon as the module is probed.
v2:
- Use dev_dbg instead of pr_debug, and take advantage of dev_name
instead of crafting pretty much the same device name locally as suggested
by Jakub Kicinski.

In the function fm10k_xmit_frame_ring, we recently switched to using
the skb_frag_size accessor instead of directly using the size member of
the skb fragment.
This made the for loop slightly harder to read because it created a very
long line that is difficult to split up. Avoid this by using a local
variable in the for loop, so that we do not have to break the line on an
open parenthesis.

After hot plugging an 1Gbps Ethernet cable with 1Gbps link partner, the
MII_BMSR may report 10Mbps, renders the network rather slow.
The issue has much lower fail rate after commit 59653e6497d1 ("e1000e:
Make watchdog use delayed work"), which essentially introduces some
delay before running the watchdog task.
But there's still a chance that the hot plugging event and the queued
watchdog task gets run at the same time, then the original issue can be
observed once again.
So let's use mod_delayed_work() to add a deterministic 1 second delay
before running watchdog task, after an interrupt.

100GbE Intel Wired LAN Driver Updates 2019-09-05
This series contains updates to ice driver.
Brett fixes the setting of num_q_vectors by using the maximum number
between the allocated transmit and receive queues.
Anirudh simplifies the code to use a helper function to return the main
VSI, which is the first element in the pf->vsi array. Adds a pointer
check to prevent a NULL pointer dereference. Adds a check to ensure we
do not initialize DCB on devices that are not DCB capable. Does some
housekeeping on the code to remove unnecessary indirection and reduce
the PF structure by removing elements that are not needed since the
values they were storing can be readily gotten from
ice_get_avail_*_count()'s. Updates the printed strings to make it
easier to search the logs for driver capabilities.
Jesse cleans up unnecessary function arguments. Updated the code to use
prefetch() to add some efficiency to the driver to avoid a cache miss.
Did some housekeeping on the code to remove the configurable transmit
work limit via ethtool which ended up creating performance overhead.
Made additional performance enhancements by updating the driver to start
out with a reasonable number of descriptors by changing the default to
2048.
Mitch fixes the reset logic for VFs by clearing VF_MBX_ARQLEN register
when the source of the reset is not PFR.
Lukasz updates the driver to include a similar fix for the i40e driver
by reporting link down for VF's when the PF queues are not enabled.
Akeem updates the driver to report the VF link status once we get VF
resources so that we can reflect the link status similarly to how the PF
reports link speed.
Ashish updates the transmit context structure based on recent changes to
the hardware specification.
Dave updates the DCB logic to allow a delayed registration for MIB
change events so that the driver is not accepting events before it is
ready for them.

The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add the ability to use unaligned chunks in the AF_XDP umem. By
relaxing where the chunks can be placed, it allows to use an
arbitrary buffer size and place whenever there is a free
address in the umem. Helps more seamless DPDK AF_XDP driver
integration. Support for i40e, ixgbe and mlx5e, from Kevin and
Maxim.
2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
application can wake up the kernel for rx/tx processing which
avoids busy-spinning of the latter, useful when app and driver
is located on the same core. Support for i40e, ixgbe and mlx5e,
from Magnus and Maxim.
3) bpftool fixes for printf()-like functions so compiler can actually
enforce checks, bpftool build system improvements for custom output
directories, and addition of 'bpftool map freeze' command, from Quentin.
4) Support attaching/detaching XDP programs from 'bpftool net' command,
from Daniel.
5) Automatic xskmap cleanup when AF_XDP socket is released, and several
barrier/{read,write}_once fixes in AF_XDP code, from Björn.

The variable rx_process_result is being initialized with a value that
is never read and is being re-assigned immediately afterwards. The
assignment is redundant, so replace it with the return from function
lan743x_rx_process_packet.

Only use the TROCR register on R-Car Gen3 as it is not present on other
SoCs.
Offsets used for the undocumented registers are considered reserved and
should not be written to. After some internal investigation with Renesas it
remains unclear why this driver accesses these fields on R-Car Gen2 but
regardless of what the historical reasons are the current code is
considered incorrect.

This patch removes the use of the undocumented BOC bit of the CCC register.
Current documentation for EtherAVB (ravb) describes the offset of what the
driver uses as the BOC bit as reserved and that only a value of 0 should be
written. After some internal investigation with Renesas it remains unclear
why this driver accesses these fields but regardless of what the historical
reasons are the current code is considered incorrect.
