Subject: [PATCH] r8169: improve RTL8411b phy-down fixup
Mirsad proposed a patch to reduce the number of spinlock lock/unlock
operations and the function code size. This can be further improved
because the function sets a consecutive register block.

This check can never be true for a firmware file with a correct format.
Existing checks in rtl_fw_data_ok() are sufficient, no problems with

Subject: [PATCH] r8169: remove multicast filter limit
Once upon a time, when r8169 was new, the multicast filter limit code
was copied from RTL8139 driver. There the filter limit is even
user-configurable.
The filtering is hash-based and we don't have perfect filtering.
Actually the mc filtering on RTL8125 still seems to be the same
as used on 8390/NE2000. So it's not clear to me which benefit it
should bring when switching to all-multi mode once a certain number
of filter bits is set. More the opposite: Filtering out at least
some unwanted mc traffic is better than no filtering.
Also the available chip documentation doesn't mention any restriction.
Therefore remove the filter limit.

Subject: [PATCH] r8169: improve handling task scheduling
If we know that the task is going to be a no-op, don't even schedule it.
And remove the check for netif_running() in the worker function, the
check for flag RTL_FLAG_TASK_ENABLED is sufficient. Note that we can't
remove the check for flag RTL_FLAG_TASK_ENABLED in the worker function
because we have no guarantee when it will be executed.

Subject: [PATCH] r8169: simplify EEE handling
We don't have to store the EEE modes to be advertised in the driver,
phylib does this for us and stores it in phydev->advertising_eee.
phylib also takes care of properly handling the EEE advertisement.

Subject: [PATCH] r8169: add generic rtl_set_eee_txidle_timer function
Add a generic setter for the EEE tx idle timer and use it with all
RTL8125/RTL8126 chip versions, in line with the vendor driver.
This prepares for adding EEE tx idle timer support for additional
chip versions.

Subject: [PATCH] net: annotate writes on dev->mtu from ndo_change_mtu()
Simon reported that ndo_change_mtu() methods were never
updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted
in commit 501a90c94510 ("inet: protect against too small
mtu values.")
We read dev->mtu without holding RTNL in many places,
with READ_ONCE() annotations.
It is time to take care of ndo_change_mtu() methods
to use corresponding WRITE_ONCE()

Vendor driver calls this bit RxDescUnavail. All we do in the interrupt
handler in this case is scheduling NAPI. If we should be out of
RX descriptors, then NAPI is scheduled anyway. Therefore remove this
interrupt source. Tested on RTL8168h.

Subject: [PATCH] r8169: remove detection of chip version 11 (early
RTL8168b)
This early RTL8168b version was the first PCIe chip version, and it's
quite quirky. Last sign of life is from more than 15 yrs ago.
Let's remove detection of this chip version, we'll see whether anybody
complains. If not, support for this chip version can be removed a few
kernel versions later.
