Update the HW MAC initialization flow. Do not gate DMA clock from
the modPHY block. Keeping this clock will prevent dropped packets

If something goes wrong in the remove callback, returning an error code
just results in an error message. The device still disappears.
So don't skip disabling the regulator in st95hf_remove() if resetting
the controller via spi fails. Also don't return an error code which just
results in two error messages.

Some Micrel KSZ8041NL PHY chips exhibit continuous RX errors after using
the power down mode bit (0.11). If the PHY is taken out of power down
mode in a certain temperature range, the PHY enters a weird state which
leads to continuously reporting RX errors. In that state, the MAC is not
able to receive or send any Ethernet frames and the activity LED is
constantly blinking. Since Linux is using the suspend callback when the
interface is taken down, ending up in that state can easily happen
during a normal startup.
Micrel confirmed the issue in errata DS80000700A [*], caused by abnormal
clock recovery when using power down mode. Even the latest revision (A4,
Revision ID 0x1513) seems to suffer that problem, and according to the
errata is not going to be fixed.
Remove the suspend/resume callback to avoid using the power down mode
completely.

The task of VF reset is performed through the workqueue. It checks the
value of hdev->reset_pending to determine whether to exit the loop.
However, the value of hdev->reset_pending may also be assigned by
the interrupt function hclgevf_misc_irq_handle(), which may cause the
loop fail to exit and keep occupying the workqueue. This loop is not
necessary, so remove it and the workqueue will be rescheduled if the
reset needs to be retried or a new reset occurs.

Currently when there is a rx page allocation failure, it is
possible that polling may be stopped if there is no more packet
to be reveiced, which may cause queue stall problem under memory
pressure.
This patch makes sure polling is scheduled again when there is
any rx page allocation failure, and polling will try to allocate
receive buffers until it succeeds.
Now the allocation retry is added, it is unnecessary to do the rx
page allocation at the end of rx cleaning, so remove it. And reset
the unused_count to zero after calling hns3_nic_alloc_rx_buffers()
to avoid calling hns3_nic_alloc_rx_buffers() repeatedly under
memory pressure.

rx unused desc is the desc that need attatching new buffer
before refilling to hw to receive new packet, the number of
desc need attatching new buffer is calculated using next_to_use
and next_to_clean. when next_to_use == next_to_clean, currently
hns3 driver assumes that all the desc has the buffer attatched,
but 'next_to_use == next_to_clean' also means all the desc need
attatching new buffer if hw has comsumed all the desc and the
driver has not attatched any buffer to the desc yet.
This patch adds 'refill' in desc_cb to indicate whether a new
buffer has been refilled to a desc.

Currently, DWRR of tc will be initialized to a fixed value when this tc
is enabled, but it is not been reset to 0 when this tc is disabled. It
cause a problem that the DWRR of unused tc is not 0 after using tc tool

This change does not fix any functional issue or address any real life
use case that wasn't possible before. It is just a small step in the
process of standardizing the way in which Ethernet MAC drivers may apply
RGMII delays (traditionally these have been applied by PHYs, with no
clear definition of what to do in the case of a fixed-link).
The sja1105 driver used to apply MAC-level RGMII delays on the RX data
lines when in fixed-link mode and using a phy-mode of "rgmii-rxid" or
"rgmii-id" and on the TX data lines when using "rgmii-txid" or "rgmii-id".
But the standard definitions don't say anything about behaving
differently when the port is in fixed-link vs when it isn't, and the new
device tree bindings are about having a way of applying the delays in a
way that is independent of the phy-mode and of the fixed-link property.
When the {rx,tx}-internal-delay-ps properties are present, use them,
otherwise fall back to the old behavior and warn.
One other thing to note is that the SJA1105 hardware applies a delay
value in degrees rather than in picoseconds (the delay in ps changes
depending on the frequency of the RGMII clock - 125 MHz at 1G, 25 MHz at
100M, 2.5MHz at 10M). I assume that is fine, we calculate the phase
shift of the internal delay lines assuming that the device tree meant
gigabit, and we let the hardware scale those according to the link speed.

This reverts commit 09e856d54bda5f288ef8437a90ab2b9b3eab83d1.
When an interface is enslaved in a VRF, prerouting conntrack hook is
called twice: once in the context of the original input interface, and
once in the context of the VRF interface. If no special precausions are
taken, this leads to creation of two conntrack entries instead of one,
and breaks SNAT.
Commit above was intended to avoid creation of extra conntrack entries
when input interface is enslaved in a VRF. It did so by resetting
conntrack related data associated with the skb when it enters VRF context.
However it breaks netfilter operation. Imagine a use case when conntrack
zone must be assigned based on the original input interface, rather than
VRF interface (that would make original interfaces indistinguishable). One
could create netfilter rules similar to these:
chain rawprerouting {
type filter hook prerouting priority raw;
iif realiface1 ct zone set 1 return
iif realiface2 ct zone set 2 return
}
This works before the mentioned commit, but not after: zone assignment
is "forgotten", and any subsequent NAT or filtering that is dependent
on the conntrack zone does not work.
Here is a reproducer script that demonstrates the difference in behaviour.
==========
#!/bin/sh
# This script demonstrates unexpected change of nftables behaviour
# caused by commit 09e856d54bda5f28 ""vrf: Reset skb conntrack
# connection on VRF rcv"
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=09e856d54bda5f288ef8437a90ab2b9b3eab83d1
#
# Before the commit, it was possible to assign conntrack zone to a
# packet (or mark it for `notracking`) in the prerouting chanin, raw
# priority, based on the `iif` (interface from which the packet
# arrived).
# After the change, # if the interface is enslaved in a VRF, such
# assignment is lost. Instead, assignment based on the `iif` matching
# the VRF master interface is honored. Thus it is impossible to
# distinguish packets based on the original interface.
#
# This script demonstrates this change of behaviour: conntrack zone 1
# or 2 is assigned depending on the match with the original interface
# or the vrf master interface. It can be observed that conntrack entry
# appears in different zone in the kernel versions before and after
# the commit.

Use dev_addr_set() to match the existing logic.
setup_card() is always passed netdev->dev_addr, so pass the netdev
pointer instead and assign the address using a helper there.

Use a buffer on the stack. Note that atmel_get_mib() is a wrapper
around atmel_copy_to_host(). For the to device direction we just
need to make sure functions respect argument being cost.

When powersaving (so either wifi powersaving or deep sleep, depending on
which state the firmware is in) is disabled, the way the firmware goes
into host sleep is different: Usually the firmware implicitely enters
host sleep on the next SLEEP event we get when we configured host sleep
via HSCFG before. When powersaving is disabled though, there are no
SLEEP events, the way we enter host sleep in that case is different: The
firmware will send us a HS_ACT_REQ event and after that we "manually"
make the firmware enter host sleep by sending it another HSCFG command
with the action HS_ACTIVATE.
Now waking up from host sleep appears to be different depending on
whether powersaving is enabled again: When powersaving is enabled, the
firmware implicitely leaves host sleep as soon as it wakes up and sends
us an AWAKE event. When powersaving is disabled though, it apparently
doesn't implicitely leave host sleep, but instead we need to send it a
HSCFG command with the HS_CONFIGURE action and the HS_CFG_CANCEL
condition. We didn't do that so far, which is why waking up from host
sleep was broken when powersaving is disabled.
So add some additional state to mwifiex_adapter where we keep track of
whether host sleep was activated manually via HS_ACTIVATE, and if that
was the case, deactivate it manually again via HS_CFG_CANCEL.

While looking at on-air packets using Wireshark, I noticed we're never
setting the initiator bit when sending DELBA requests to the AP: While
we set the bit on our del_ba_param_set bitmask, we forget to actually
copy that bitmask over to the command struct, which means we never
actually set the initiator bit.
Fix that and copy the bitmask over to the host_cmd_ds_11n_delba command
struct.
