There are two points with the calculation of RX buffer size which are
not optimal:
1. dev->mtu is a mutual parameter and it's currently initialized with
QCAFRM_MAX_MTU. But for RX buffer size calculation we always need the
maximum possible MTU. So better use the define directly.
2. This magic number 4 represent the hardware generated frame length
which is specific to SPI. We better replace this with the suitable
define.

ethtool: switch EEE netlink interface to use EEE linkmode bitmaps
So far only 32bit legacy bitmaps are passed to userspace. This makes
it impossible to manage EEE linkmodes beyond bit 32, e.g. manage EEE
for 2500BaseT and 5000BaseT. This series adds support for passing
full linkmode bitmaps between kernel and userspace.
Fortunately the netlink-based part of ethtool is quite smart and no
changes are needed in ethtool. However this applies to the netlink
interface only, the ioctl interface for now remains restricted to
legacy bitmaps.
Next step will be adding support for the c45 EEE2 standard registers
(3.21, 7.62, 7.63) to the genphy_c45 functions dealing with EEE.
I have a follow-up series for this ready to be submitted.
v2:
- now as RFC
- adopt suggestion from Andrew to start with struct ethtool_keee
being an identical copy of ethtool_eee, and switch all users
v3:
- switch from RFC to net-next
- add patch 4, and reuse old names in patch 5
- rebase patch 1

selftests: Add TEST_INCLUDES directive and adjust tests to use it
After commit 25ae948b44 ("selftests/net: add lib.sh") but before commit
2114e83381 ("selftests: forwarding: Avoid failures to source
net/lib.sh"), some net selftests encountered errors when they were being
exported and run. This was because the new net/lib.sh was not exported
along with the tests. The errors were crudely avoided by duplicating some
content between net/lib.sh and net/forwarding/lib.sh in 2114e83381.
In order to restore the sourcing of net/lib.sh from net/forwarding/lib.sh
and remove the duplicated content, this series introduces a new selftests
Makefile variable to list extra files to export from other directories and
makes use of it to avoid reintroducing the errors mentioned above.

selftests: forwarding: Remove executable bits from lib.sh

Since commit 2114e83381 ("selftests: forwarding: Avoid failures to source
net/lib.sh") resolved the test errors, this version of the series is
focused on removing the duplication that was added in that commit. Directly
rebasing the series would reintroduce the problems that 2114e83381
avoided before fixing them again. In order to prevent such breakage partway
through the series, patches are reordered and content changed slightly but
there is no diff at the end compared with the simple rebasing approach. I
have dropped most review tags on account of this reordering.

commit 25ae948b44 ("selftests/net: add lib.sh") added net/lib.sh to
contain code shared by tests under net/ and net/forwarding/. However, this
caused issues with selftests from directories other than net/forwarding/,
in particular those under drivers/net/. Those issues were avoided in a
simple way by duplicating some content in commit 2114e83381 ("selftests:
forwarding: Avoid failures to source net/lib.sh").
In order to remove the duplicated content, restore the inclusion of
net/lib.sh from net/forwarding/lib.sh but with the following changes:
* net/lib.sh is imported through the net_forwarding_dir path
The original expression "source ../lib.sh" would look for lib.sh in the
directory above the script file's one, which did not work for tests under
drivers/net/.
* net/lib.sh is added to TEST_INCLUDES
Since net/forwarding/lib.sh now sources net/lib.sh, both of those files
must be exported along with tests which source net/forwarding/lib.sh.

In the last patch of this series, net/forwarding/lib.sh will source lib.sh
from its parent directory (ie. net/lib.sh). This would not work for dsa
tests because net/lib.sh is not present under drivers/net/.
Since the tests in net/forwarding/ are not meant to be copied and run from
another directory, as a preparation for that last patch, replace the test
symlinks by a wrapper script which runs the original tests under
net/forwarding/. Following from that, the links to shared library scripts

Some tests written in bash source other files in a parent directory. For
example, drivers/net/bonding/dev_addr_lists.sh sources
net/forwarding/lib.sh. If a subset of tests is exported and run outside the
source tree (for example by using `make -C tools/testing/selftests gen_tar
TARGETS="drivers/net/bonding"`), these other files must be made available
as well.
Commit ae108c48b5 ("selftests: net: Fix cross-tree inclusion of scripts")
addressed this problem by symlinking and copying the sourced files but this
only works for direct dependencies. Commit 25ae948b44 ("selftests/net:
add lib.sh") changed net/forwarding/lib.sh to source net/lib.sh. As a
result, that latter file must be included as well when the former is
exported. This was not handled and was reverted in commit 2114e83381
("selftests: forwarding: Avoid failures to source net/lib.sh"). In order to
allow reinstating the inclusion of net/lib.sh from net/forwarding/lib.sh,
add a mechanism to list dependent files in a new Makefile variable and
export them. This allows sourcing those files using the same expression
whether tests are run in-tree or exported.
Dependencies are not resolved recursively so transitive dependencies must
be listed in TEST_INCLUDES. For example, if net/forwarding/lib.sh sources
net/lib.sh; the Makefile related to a test that sources
net/forwarding/lib.sh from a parent directory must list:

The Synopsys DesignWare MAC found on StarFive JH7100 SoC is mostly
similar to the newer JH7110, but it requires only two interrupts and a
single reset line, which is 'ahb' instead of the commonly used
'stmmaceth'.
Since the common binding 'snps,dwmac' allows selecting 'ahb' only in
conjunction with 'stmmaceth', extend the logic to also permit exclusive
usage of the 'ahb' reset name. This ensures the following use cases are
supported:
JH7110: reset-names = "stmmaceth", "ahb";
JH7100: reset-names = "ahb";
other: reset-names = "stmmaceth";
Also note the need to use a different dwmac fallback, as v5.20 applies
to JH7110 only, while JH7100 relies on v3.7x.
Additionally, drop the reset description items from top-level binding as
they are already provided by the included snps,dwmac schema.

When port function state change is requested, and when the driver
does not support it, it refers to the hw address attribute instead
of state attribute. Seems like a copy paste error.
Fix it by referring to the port function state attribute.

The original idea of the delay_time check was to not apply multicast
snooping too early when an MLD querier appears. And to instead wait at
least for MLD reports to arrive before switching from flooding to group
based, MLD snooped forwarding, to avoid temporary packet loss.
However in a batman-adv mesh network it was noticed that after 248 days of
uptime 32bit MIPS based devices would start to signal that they had
stopped applying multicast snooping due to missing queriers - even though
they were the elected querier and still sending MLD queries themselves.
While time_is_before_jiffies() generally is safe against jiffies
wrap-arounds, like the code comments in jiffies.h explain, it won't
be able to track a difference larger than ULONG_MAX/2. With a 32bit
large jiffies and one jiffies tick every 10ms (CONFIG_HZ=100) on these MIPS
devices running OpenWrt this would result in a difference larger than
ULONG_MAX/2 after 248 (= 2^32/100/60/60/24/2) days and
time_is_before_jiffies() would then start to return false instead of
true. Leading to multicast snooping not being applied to multicast
packets anymore.
Fix this issue by using a proper timer_list object which won't have this
ULONG_MAX/2 difference limitation.
Fixes: b00589af3b ("bridge: disable snooping if there is no querier")

One of the test cases in the test_bridge_backup_port.sh selftest relies
on a matchall classifier to drop unrelated traffic so that the Tx drop
counter on the VXLAN device will only be incremented as a result of
traffic generated by the test.
However, the configuration option for the matchall classifier is
missing from the configuration file which might explain the failures we
see in the netdev CI [1].
Fix by adding CONFIG_NET_CLS_MATCHALL to the configuration file.

Class-based I2C probing requires detect() and address_list to be
set in the I2C client driver, see checks in i2c_detect().
It's misleading to declare I2C_CLASS_HWMON support if this
precondition isn't met.

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So a -1 has been added when needed.
