This reverts commit 3bda2e5df476417b6d08967e2d84234a59d57b1c.
According to discussion with Andrew as follow:
https://lore.kernel.org/netdev/09eda9fe-196b-006b-6f01-f54e75715961@huawei.com/
HNS3 driver needs to separate pause autoneg from general autoneg, so revert
this incorrect patch.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it go through appropriate helpers.
Even though the current code uses dev->addr_len the we can switch
to eth_hw_addr_set() instead of dev_addr_set(). The netdev is
always allocated by alloc_etherdev_mq() and there are at least two
places which assume Ethernet address:
- the line below calling eth_hw_addr_random()
- virtnet_set_mac_address() -> eth_commit_mac_addr_change()

CN10k SoCs use atomic stores of up to 128 bytes to submit
packets/instructions into co-processor cores. The enqueueing is performed
using Large Memory Transaction Store (LMTST) operations. They allow for
lockless enqueue operations - i.e., two different CPU cores can submit
instructions to the same queue without needing to lock the queue or
synchronize their accesses.
This patch implements a new debugfs entry for dumping LMTST map
table present on CN10K, as this might be very useful to debug any issue
in case of shared LMTST region among multiple pci functions.

Currently, we are using a fixed buffer size of length 2048 to display
rsrc_alloc output. As a result a maximum of 2048 characters of
rsrc_alloc output is displayed, which may lead sometimes to display only
partial output. This patch fixes this dependency on max limit of buffer
size and displays all PF VF entries.
Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12
characters to print the list of LFs of each block for a PF/VF. If the
length of list of LFs of a block exceeds this fixed width then the list
gets truncated and displays only a part of the list. This patch fixes
this by using the maximum possible length of list of LFs among all
blocks of all PFs and VFs entries as the width size.

Add the missing endpoint sanity checks to probe() to avoid division by
zero in mwifiex_write_data_sync() in case a malicious device has broken
descriptors (or when doing descriptor fuzz testing).
Only add checks for the firmware-download boot stage, which require both
command endpoints, for now. The driver looks like it will handle a
missing endpoint during normal operation without oopsing, albeit not
very gracefully as it will try to submit URBs to the default pipe and
fail.
Note that USB core will reject URBs submitted for endpoints with zero
wMaxPacketSize but that drivers doing packet-size calculations still
need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip
endpoint descriptors with maxpacket=0")).

'index.table' is a bitmap. So use 'bitmap_zalloc()' to simplify code,
improve the semantic and avoid some open-coded arithmetic in allocator
arguments.
Using 'bitmap_zalloc()' also allows the removal of a now useless
'bitmap_zero()'.
Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.

The monitor pages in the CHANNELMSG_INITIATE_CONTACT msg are shared
with host in Isolation VM and so it's necessary to use hvcall to set

address should be in the extra space which is above shared gpa

shared_gpa_boundary).

to store monitor page virtual address returned by hv_alloc_hyperv_
zeroed_page() and free monitor page via monitor_pages_original in
the vmbus_disconnect(). The monitor_pages[] is to used to access
monitor page and it is initialized to be equal with monitor_pages_
original. The monitor_pages[] will be overridden in the isolation VM
with va of extra address. Introduce monitor_pages_pa[] to store
monitor pages' physical address and use it to populate pa in the
initiate msg.

Hyperv provides GHCB protocol to write Synthetic Interrupt
Controller MSR registers in Isolation VM with AMD SEV SNP
and these registers are emulated by hypervisor directly.
Hyperv requires to write SINTx MSR registers twice. First
writes MSR via GHCB page to communicate with hypervisor
and then writes wrmsr instruction to talk with paravisor
which runs in VMPL0. Guest OS ID MSR also needs to be set
via GHCB page.

information from CQHCI registers, otherwise, it will hang in MediaTek mmc
host controller.
