Broadcom iProc based SoCs use a MDIO bus multiplexer where child buses
could be internal as well external to SoCs. These buses could supports
MDIO transaction compatible to C-22/C-45.
Broadcom MDIO bus multiplexer is an integrated multiplexer where child bus
selection and mdio transaction logic lies inside multiplexer itself.
To accommodate this multiplexer in existing mux framework below changes
were required-
1. Passed MDIO parent bus via mdio_mux_init to MDIO mux framework.
This patch set includes MDIO bus multiplexer driver along with above
framework change. It includes one external bus node having Ethernet PHY
attached and two internal bus node holding PCIe PHYs.
This patch series is based on v4.7-rc1 and is available from github-
repo: https://github.com/Broadcom/arm64-linux.git
branch:mdio-mux-v5
-Changes from v4:
- disabled PCIe PHYs from dtsi and enabled in dts file.
-Changes from v3:
- Unregister and free the parent MDIO bus.
- rebased on net-next/master branch.
Reason for resend:
-Rebased on v4.7-rc1
Changes from v2:
-Addressed Rob's comments in this patch regarding typo/grammers.
-Addressed David's comments regarding local variables order.
-Removed property "mdio-integrated-mux" and used mdiobus_register()
in place of of_mdiobus_regsiter().
-removed usage of IS_ERR_OR_NULL to IS_ERR in PCIe PHY driver.
Changes from v1:
- stop using "brcm,is_c45" from bus node as suggested by Andrew. MDIO
PHY driver will logically OR MII_ADDR_C45 into the address when issues

rxrpc: Limit the listening backlog
Limit the socket incoming call backlog queue size so that a remote client
can't pump in sufficient new calls that the server runs out of memory. Note
that this is partially theoretical at the moment since whilst the number of
calls is limited, the number of packets trying to set up new calls is not.
This will be addressed in a later patch.
If the caller of listen() specifies a backlog INT_MAX, then they get the
current maximum; anything else greater than max_backlog or anything
negative incurs EINVAL.
The limit on the maximum queue size can be set by:
echo N >/proc/sys/net/rxrpc/max_backlog
where 4<=N<=32.
Further, set the default backlog to 0, requiring listen() to be called
before we start actually queueing new calls. Whilst this kind of is a
change in the UAPI, the caller can't actually *accept* new calls anyway
unless they've first called listen() to put the socket into the LISTENING
state - thus the aforementioned new calls would otherwise just sit there,
eating up kernel memory. (Note that sockets that don't have a non-zero
service ID bound don't get incoming calls anyway.)
Given that the default backlog is now 0, make the AFS filesystem call
kernel_listen() to set the maximum backlog for itself.
Possible improvements include:
(1) Trimming a too-large backlog to max_backlog when listen is called.
(2) Trimming the backlog value whenever the value is used so that changes
to max_backlog are applied to an open socket automatically. Note that
the AFS filesystem opens one socket and keeps it open for extended
periods, so would miss out on changes to max_backlog.
(3) Having a separate setting for the AFS filesystem.

net, cls: allow for deleting all filters for given parent
Add a possibility where the user can just specify the parent and
all filters under that parent are then being purged. Currently,
for example for scripting, one needs to specify pref/prio to have
a well-defined number for 'tc filter del' command for addressing
the previously created instance or additionally filter handle in
case of priorities being the same. Improve usage by allowing the
option for tc to specify the parent and removing the whole chain
for that given parent.
Example usage after patch, no tc changes required:
# tc qdisc replace dev foo clsact
# tc filter add dev foo egress bpf da obj ./bpf.o
# tc filter add dev foo egress bpf da obj ./bpf.o
# tc filter show dev foo egress
filter protocol all pref 49151 bpf
filter protocol all pref 49151 bpf handle 0x1 bpf.o:[classifier] direct-action
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bpf.o:[classifier] direct-action
# tc filter del dev foo egress
# tc filter show dev foo egress
#
Previously, RTM_DELTFILTER requests with invalid prio of 0 were
rejected, so only netlink requests with RTM_NEWTFILTER and NLM_F_CREATE
flag were allowed where the kernel would auto-generate a pref/prio.
We can piggyback on that and use prio of 0 as a wildcard for
requests of RTM_DELTFILTER.
For notifying tc netlink monitoring users (e.g. libnl uses this
for caching), there are two options, that is, sending individual
tfilter_notify() notifications for each tcf_proto, or sending a
single one indicating wildcard removal. I tried both and there
are pros and cons for each, eventually I decided for sending
individual tfilter_notify(), so that user space can support this
seamlessly and there won't be a mess of changing each and every
application to make sure expectations from the kernel won't break
when they don't understand single notification. Since linear chains
don't really scale, I expect only a handful of classifiers to be
attached at max for a given parent anyway.

(&lio->txq_status_wq.wk.work which maps to octnet_poll_check_txq_status)

The problem above is due to the fact that the fib hash table is not

Simplify the RxRPC connect() implementation. It will just note the
destination address it is given, and if a sendmsg() comes along with no
address, this will be assigned as the address. No transport struct will be
held internally, which will allow us to remove this later.
Simplify sendmsg() also. Whilst a call is active, userspace refers to it
by a private unique user ID specified in a control message. When sendmsg()
sees a user ID that doesn't map to an extant call, it creates a new call
for that user ID and attempts to add it. If, when we try to add it, the
user ID is now registered, we now reject the message with -EEXIST. We
should never see this situation unless two threads are racing, trying to
create a call with the same ID - which would be an error.
It also isn't required to provide sendmsg() with an address - provided the
control message data holds a user ID that maps to a currently active call.

This is long overdue, finally add support for VLANs in the Broadcom Starfigther

There are a few things that make us differ from e.g; mv88e6xxx.c:
- we keep a software cache of which VLANs are enabled and which are not to
dramatically speed up the VLAN dump operation, we do not have any HW operation
which would only return the list of valid VLAN entries, they would have to be
all queried one by one, with 4K vlans, this takes a while
- the default behavior is equivalent to setting VLAN filtering to 1, still working
on implementing a proper port_vlan_filtering callback, but I figured the most
conservative behavior is probably okay anyway
- without enabling VLANs, the default behavior is to receive any 802.1q frames
(per the DSA documentation), however, once we start enabling VLAN support, if
an interface leaves the bridge, we still want it to receive all 802.1q frames
so we utiliez the "Join all VLAN" feature of the switch to perform that

net/mlx5e: Fix blue flame quota logic
Blue flame is a latency enhancement feature that allows the driver to
write the packet data directly to the NIC's registers thus making the
read of the packet data from host memory redundant.
We maintain a quota for the blue flame which is reloaded whenever we
identify that the hardware is processing send requests and processes
them fast enough so by the time we post the next send request it was
able to process all the pending ones. This indicates that the hardware
is capable of processing more blue flame requests efficiently. The blue
flame quota is decremented whenever we send using blue flame.
The current code erroneously clears the budget if we did not use blue
flame for the current post send operation and we fix it here.
