The tg3_set_eeprom() function correctly initializes the 'start' variable,
but gcc generates a false warning:
drivers/net/ethernet/broadcom/tg3.c: In function 'tg3_set_eeprom':
drivers/net/ethernet/broadcom/tg3.c:12057:4: warning: 'start' may be used uninitialized in this function [-Wmaybe-uninitialized]
I have not come up with a way to restructure the code in a way that
avoids the warning without making it less readable, so this adds an
initialization for the declaration to shut up that warning.

The nb8800_poll() function initializes the 'next' variable in the
loop looking for new input data. We know this will be called at
least once because 'budget' is a guaranteed to be a positive number
when we enter the function, but the compiler doesn't know that
and warns when the variable is used later:

drivers/net/ethernet/aurora/nb8800.c:350:21: warning: 'next' may be used uninitialized in this function [-Wmaybe-uninitialized]
Changing the 'while() {}' loop to 'do {} while()' makes it obvious
to the compiler what is going on so it no longer warns.

When CONFIG_PCI_MSI is disabled, we get warnings about unused functions
in the vxge driver:

We could add another #ifdef here, but it's nicer to avoid those warnings
for good by converting the existing #ifdef to if(IS_ENABLED()), which has
the same effect but provides better compile-time coverage in general,
and lets the compiler understand better when the function is intentionally

The bgmac driver depends on BCMA_HOST_SOC, which is only used
when CONFIG_BCMA is enabled. However, it is a bool option and can
be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading
to an obvious link error:
drivers/built-in.o: In function `bgmac_init':
:(.init.text+0x7f2c): undefined reference to `__bcma_driver_register'
drivers/built-in.o: In function `bgmac_exit':
:(.exit.text+0x110a): undefined reference to `bcma_driver_unregister'
To avoid this case, we need to depend on both BCMA and BCMA_SOC,
as this patch does. I'm also trying to make the dependency more
readable by splitting it into three lines, and adding a COMPILE_TEST
alternative so we can test-build it in all configurations that
support BCMA.
The added dependency on FIXED_PHY addresses a related issue where
we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and
CONFIG_BGMAC=y.

The davinci_cpdma mixes up physical addresses as seen from the CPU
and DMA addresses as seen from a DMA master, since it can operate
on both normal memory or an on-chip buffer. If dma_addr_t is
different from phys_addr_t, this means we get a compile-time warning
about the type mismatch:
ethernet/ti/davinci_cpdma.c: In function 'cpdma_desc_pool_create':
ethernet/ti/davinci_cpdma.c:182:48: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]

static inline void *dma_alloc_coherent(struct device *dev, size_t size,
This slightly restructures the code so the address we use for
mapping RAM into a DMA address is always a dma_addr_t, avoiding
the warning. The code is correct even if both types are 32-bit
because the DMA master in this device only supports 32-bit addressing
anyway, independent of the types that are used.
We still assign this value to pool->phys, and that is wrong if
the driver is ever used with an IOMMU, but that value appears to
be never used, so there is no problem really. I've added a couple
of comments about where we do things that are slightly violating
the API.

Currently the port based VLAN maps should be configured to allow every
port to egress frames on all other ports, except themselves.
The debugfs interface shows that they are misconfigured. For instance, a

GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6
...
6: 1fa4 1f0f 4 7f 7e 7d 7c 7b 7a 79

This means that port 3 is allowed to talk to port 2-6, but cannot talk

except 3 itself:

This leaves the basic logic alone and uses normal pointers for

to access them, we also introduce our own moxart_desc_read
moxart_desc_write helpers that perform the same endianess swap
as the original code, but without the address space conversion.
The barriers are made explicit here where needed: Even in the worst-case
scenario, we just have to use a rmb() after checking ownership so
we don't read any input data before we are sure it is value, and we
use wmb() before transferring ownership back to the device.

Currently when a macvlan is being initialized and the lower device is
netif_carrier_ok(), the macvlan device doesn't run through
rfc2863_policy() and is left with UNKNOWN operstate. Fix it by adding an
unconditional linkwatch event for the new macvlan device. Similar fix is
already used by the 8021q device (see register_vlan_dev()). Also fix the
inconsistent state when the lower device has been down and its carrier
was changed (when a device is down NETDEV_CHANGE doesn't get generated).
The second issue can be seen f.e. when we have a macvlan on top of a 8021q
device which has been down and its real device has been changing carrier
states, after setting the 8021q device up, the macvlan device will have
the same carrier state as it was before even though the 8021q can now
have a different state.
Example for case 1:
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP mode DEFAULT group default qlen 1000
$ ip l add l eth2 macvl0 type macvlan
$ ip l set macvl0 up
$ ip l sh macvl0
72: macvl0@eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UNKNOWN mode DEFAULT group default
link/ether f6:0b:54:0a:9d:a3 brd ff:ff:ff:ff:ff:ff
Example for case 2 (order is important):
Prestate: eth2 UP/CARRIER, vlan1 down, vlan1-macvlan down
$ ip l set vlan1-macvlan up
$ ip l sh vlan1-macvlan
71: vlan1-macvlan@vlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
qdisc noqueue state UNKNOWN mode DEFAULT group default
link/ether 4a:b8:44:56:b9:b9 brd ff:ff:ff:ff:ff:ff
[ eth2 loses CARRIER before vlan1 has been UP-ed ]
$ ip l sh eth2
4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast
state DOWN mode DEFAULT group default qlen 1000
link/ether 52:54:00:bf:57:16 brd ff:ff:ff:ff:ff:ff
$ ip l sh vlan1-macvlan
71: vlan1-macvlan@vlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
qdisc noqueue state UNKNOWN mode DEFAULT group default
link/ether 4a:b8:44:56:b9:b9 brd ff:ff:ff:ff:ff:ff
$ ip l set vlan1 up
$ ip l sh vlan1
70: vlan1@eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc
noqueue state LOWERLAYERDOWN mode DEFAULT group default qlen 1000
link/ether 52:54:00:bf:57:16 brd ff:ff:ff:ff:ff:ff
$ ip l sh vlan1-macvlan
71: vlan1-macvlan@vlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
qdisc noqueue state UNKNOWN mode DEFAULT group default
link/ether 4a:b8:44:56:b9:b9 brd ff:ff:ff:ff:ff:ff
vlan1-macvlan is still UP, still has carrier and is still in the same
operstate as before. After the patch in case 1 macvl0 has state UP as it
should and in case 2 vlan1-macvlan has state LOWERLAYERDOWN again as it
should. Note that while the lower macvlan device is down their carrier
and thus operstate can go out of sync but that will be fixed once the
lower device goes up again.
This behaviour seems to have been present since beginning of git history.

When switchdev drivers process FDB notifications from the underlying
device they resolve the netdev to which the entry points to and notify
the bridge using the switchdev notifier.
However, since the RTNL mutex is not held there is nothing preventing
the netdev from disappearing in the middle, which will cause
br_switchdev_event() to dereference a non-existing netdev.
Make switchdev drivers hold the lock at the beginning of the

notifying the bridge.
Also, remove switchdev_mutex and fdb_lock, as they are no longer needed

aged-out. We can otherwise have an inconsistency between software and
hardware tables.

When port is put into LISTENING state it shouldn't populate the FDB, so
set the port's STP state in hardware to DISCARDING instead of LEARNING.
It will therefore keep listening to BPDU packets, but discard other
non-control packets and won't perform any learning.

When STP state is set to DISABLED the port is assumed to be inactive, but
currently we forward packets ingressing through it.
Instead, set the port's STP state in hardware to DISCARDING, which means
it doesn't forward packets or perform any learning, but it does trap
control packets. However, these packets will be dropped by bridge code,
which results in the expected behavior.

As explained in previous commit, we should always take care of flushing
the FDB in the driver and not rely on bridge code.
We need to distinguish between two cases with regards to LAG:
1) Port is leaving LAG while LAG is bridged (or VLAN devices on top of
it). In this case don't flush the FDB entries pointing to the LAG ID, as
this will affect other ports still member in the LAG. Only flush the FDB
when the last port in the LAG is leaving the bridge.
2) LAG device is leaving the bridge. In this case the CHANGEUPPER event
is simply propagated to each member port, so make each port flush the
FDB in its turn.
Note that emptying a bridged LAG from ports creates an inconsistency
between hardware and software. A user who later (< ageing_time)
re-populates the LAG won't have any FDB entries pointing to the LAG ID
in hardware, but they will be present in the software bridge's FDB.
Currently there is no good solution to this problem, but this will be
addressed by us in the future.
In order to optimize the flushing process, flush by port or LAG ID if
there are no VLAN interfaces on top of the port. Otherwise, flush using
(Port / LAG ID, FID=VID} for each of the lower 4K FIDs. In the case of
VLAN device simply flush using {Port / LAG ID, vFID} with the vFID to
which the VLAN device is mapped to.

When removing a net device from a bridge we should flush the FDB entries
associated with this net device. Up until now, we relied upon bridge
code to do that for us, but it is possible for user to prevent hardware
from syncing with the software bridge (learning_sync=0), so we need to
flush overselves.
Add the Switch Filtering DB Flush (SFDF) register that is used to flush
FDB entries according to different parameters (per-port, per-FID etc).

It is possible for a user to remove a port from a LAG device, while the
LAG device or VLAN devices on top of it are bridged. In these cases,
bridge's teardown sequence is never issued, so we need to take care of
it ourselves.
When LAG's unlinking event is received by port netdev:
1) Traverse its vPorts list and make those member in a bridge leave it.
They will be deleted later by LAG code.
2) Make the port netdev itself leave its bridge if member in one.

Like how pci.c exposes hif ops for the bus specific operation,
expose similar hif ops table for ahb with all required functions
linked to it. Many ath10k_pci_* functions are reused here in hif ops
table. If something is not sharable, new functions are added for ahb
and linked to hif ops table.
Finally, make ath10k_ahb_probe/remove() to perform what is expected
out of it.
