In order to implement byte queue limits (bql) in CAN drivers, the length of the
CAN frame needs to be passed into the networking stack after queueing and after
transmission completion.
To avoid to calculate this length twice, extend can_get_echo_skb() to return
that value. Convert all users of this function, too.

Add a frame_len argument to can_put_echo_skb() which is used to save length of
the CAN frame into field frame_len of struct can_skb_priv so that it can be
later used after transmission completion. Convert all users of this function,
too.
Drivers which implement BQL call can_put_echo_skb() with the output of
can_skb_get_frame_len(skb) and drivers which do not simply pass zero as an
input (in the same way that NULL would be given to can_get_echo_skb()). This
way, we have a nice symmetry between the two echo functions.

This patch adds the function can_skb_get_frame_len() which returns the length
of a CAN frame on the data link layer, including Start-of-frame, Identifier,
various other bits, the actual data, the CRC, the End-of-frame, the Inter frame
spacing.

If the length paramter in len2dlc() exceeds the size of the len2dlc array, we
return 0xF. This is equal to the last 16 members of the array.
This patch removes these members from the array, uses ARRAY_SIZE() for the
length check, and returns CANFD_MAX_DLC (which is 0xf).

Since the original mtu is not used when the mtu is updated,
the mtu is aligned with cache, this will get an incorrect.

TID stuck is seen when there is a race in
CPL_PASS_ACCEPT_RPL/CPL_ABORT_REQ and abort is arriving
before the accept reply, which sets the queue number.

incorrect ingress queue.

Currently, the function i40e_construct_skb_zc only frees the input xdp
buffer when the output skb is successfully built. On error, the
function i40e_clean_rx_irq_zc does not commit anything for the current
packet descriptor and simply exits the packet descriptor processing
loop, with the plan to restart the processing of this descriptor on
the next invocation. Therefore, on error the ring next-to-clean
pointer should not advance, the xdp i.e. *bi buffer should not be
freed and the current buffer info should not be invalidated by setting
*bi to NULL. Therefore, the *bi should only be set to NULL when the
function i40e_construct_skb_zc is successful, otherwise a NULL *bi
will be dereferenced when the work for the current descriptor is
eventually restarted.

This patch adds support to install flow rules using ipv4 proto or
ipv6 next header field to distinguish between tcp/udp/sctp/esp/ah
flows when user doesn't specify the other match creteria related to
the flow such as tcp/udp/sctp source port and destination port, ah/esp
spi value. This is achieved by matching the layer type extracted by
NPC HW into the search key. Modified the driver to use Ethertype as
match criteria when user doesn't specify source IP address and dest
IP address. The esp/ah flow rule matching using security parameter
index (spi) is not supported as of now since the field is not extracted
into MCAM search key. Modified npc_check_field function to return bool.

Use of __napi_schedule_irqoff() is not safe with PREEMPT_RT in which
hard interrupts are not disabled while running the threaded interrupt.
Using __napi_schedule() works for both PREEMPT_RT and mainline Linux,
just at the cost of an additional check if interrupts are disabled for
mainline (since they are already disabled).
Similar to the fix done for enetc commit 215602a8d212 ("enetc: use
napi_schedule to be compatible with PREEMPT_RT")

Miss path handling of tc multi chain filters (i.e. filters that are
defined on chain > 0) requires the hardware to communicate to the
driver the last chain that was processed. This is possible only when
the hardware is capable of performing the combination of modify header
and forward to table actions. Currently, if the hardware is missing
this capability then the driver only offloads rules that are defined
on tc chain 0 prio 1. However, this restriction can be relaxed because
packets that miss from chain 0 are processed through all the
priorities by tc software.
Allow the offload of all the supported priorities for chain 0 even
when the hardware is not capable to perform modify header and goto
table actions.

The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts
used by the RDMA driver correctly when the RDMA driver is freeing the
MSIX vectors. It assumes that if the RDMA driver is registered, the
additional stats contexts will be needed. This is not true when the
RDMA driver is about to unregister and frees the MSIX vectors.
This slight error leads to over accouting of the stats contexts needed
after the RDMA driver has unloaded. This will cause some firmware
warning and error messages in dmesg during subsequent config. changes
or ifdown/ifup.
Fix it by properly accouting for extra stats contexts only if the
RDMA driver is registered and MSIX vectors have been successfully
requested.

This commit enables the use of the r8153_ecm driver, introduced with
commit c1aedf015ebdd0 ("net/usb/r8153_ecm: support ECM mode for
RTL8153") for the Lenovo Powered USB-C Hub (17ef:721e) based on the
Realtek RTL8153B chip.
This results in the following driver preference:
- if r8152 is available, use the r8152 driver
- if r8152 is not available, use the r8153_ecm driver
This is done to prevent the NIC from constantly sending pause frames
when the host system enters standby (fixed by using the r8152 driver
in "r8152: Add Lenovo Powered USB-C Travel Hub"), while still allowing
the device to work with the r8153_ecm driver as a fallback.

This USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip used to
use the cdc_ether driver. However, using this driver, with the system
suspended the device constantly sends pause-frames as soon as the
receive buffer fills up. This causes issues with other devices, where
some Ethernet switches stop forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.

The PHYLIB must be selected to provide mdiobus_*() functions, and the
MICREL_PHY is necessary too, as that is the only possible PHY attached
to the KS8851 (it is the internal PHY).

Commit bedd8d78aba3 ("net: phy: smsc: LAN8710/20: add phy refclk in
support") added the phy clk support. The commit already checks if
clk_get_optional() throw an error but instead of returning the error it
ignores it.

MSFT ActiveSync implementation requires that the size of the response for
incoming query is to be provided in the request input length. Failure to
set the input size proper results in failed request transfer, where the
ActiveSync counterpart reports the NDIS_STATUS_INVALID_LENGTH (0xC0010014L)
error.
Set the input size for OID_GEN_PHYSICAL_MEDIUM query to the expected size
of the response in order for the ActiveSync to properly respond to the
request.

Patch didn't fix any issue, just improve parse flow
and align ipv4 parse flow with ipv6 parse flow.
Currently ipv4 kenguru parser first check IP protocol(TCP/UDP)
and then destination IP address.
Patch introduce reverse ipv4 parse, first destination IP address parsed
and only then IP protocol.
This would allow extend capability for packet L4 parsing and align ipv4
parsing flow with ipv6.

bareudp_dellink() only needs the device list to hand it to
unregister_netdevice_queue(). We can pass NULL in, and
unregister_netdevice_queue() will do the unregistering.
There is no chance for batching on the error path, anyway.
