As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and
C0_RX_PEND interrupt outputs provide a single transmit interrupt
that combines transmit channel interrupts TXPEND[7:0] and a
single receive interrupt that combines receive channel interrupts
RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are
connected to the ARM Cortex-A8 interrupt controller (INTC) rather
than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even
though CPSW interrupt is cleared by writing appropriate values to
EOI register the interrupt is not cleared in IRQ controller. So
interrupt is still pending and CPU is struck in ISR, the
workaround is to disable the interrupts in ARM irq controller.

When a system has multiple ethernet devices and during DHCP
request (for using NFS), the system waits only for HZ/2 which is
500mS before switching to another interface for DHCP.
There are some routers (Ex: Trendnet routers) which responds to
DHCP request at about 560mS. When the system has only one
ethernet interface there is no issue as the timeout is 2S and the
dev xid doesn't changes and only retries.
But when the system has multiple Ethernet like DRA74x with CPSW
in dual EMAC mode, the DHCP response is dropped as the dev xid
changes while shifting to the next device. So changing inter
device timeout to HZ (which is 1S).

Current filer rule optimization is broken in several ways:
(1) Can perform reads/writes beyond end of allocated tables.
(gianfar_ethtool.c:1326).
(2) It breaks badly for rules with more than 2 specifiers
(e.g. matching ip, port, tos).
Example:
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 tos 1 action 1
Added rule with ID 254
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 tos 2 action 9
Added rule with ID 253
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 tos 3 action 17
Added rule with ID 252
# ./filer_decode /sys/kernel/debug/gfar1/filer_raw

ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000
(Entire cluster gets AND-ed together).
(3) We observed that the masking rules it generates do not
play well with clustering on P2020. Only first rule
of the cluster would ever fire. Given that optimizer
relies heavily on masking this is very hard to fix.
Example:
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 action 1
Added rule with ID 254
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 action 9
Added rule with ID 253
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 action 17
Added rule with ID 252
# ./filer_decode /sys/kernel/debug/gfar1/filer_raw
00: MASK == 00000210 AND Q:00 ctrl:00000080 prop:00000210
01: FPR == 00000210 AND CLE Q:00 ctrl:00000281 prop:00000210
02: MASK == ffffffff AND Q:00 ctrl:00000080 prop:ffffffff
03: DPT == 00000003 AND Q:00 ctrl:0000008e prop:00000003
04: DIA == 0a000003 Q:11 ctrl:0000440c prop:0a000003
05: DPT == 00000002 AND Q:00 ctrl:0000008e prop:00000002
06: DIA == 0a000002 Q:09 ctrl:0000240c prop:0a000002
07: DIA == 0a000001 AND Q:00 ctrl:0000008c prop:0a000001
08: DPT == 00000001 CLE Q:01 ctrl:0000060e prop:00000001
ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000
Which looks correct according to the spec but only the first
(eth id 252)/last added rule for 10.0.0.3 will ever trigger.
As if filer did not treat the AND CLE as cluster start but
also kept AND-ing the rules. We found no errata covering this.
The fact that nobody noticed (2) or (3) makes me think
that this feature is not very widely used and we should just
remove it.

When the first slave is added (such as during bootup) the first

In case we need to divert reads/writes using the slave MII bus, we may have
already fetched a valid PHY interface property from Device Tree, and that
mode is used by the PHY driver to make configuration decisions.
If we could not fetch the "phy-mode" property, we will assign p->phy_interface
to PHY_INTERFACE_MODE_NA, such that we can actually check for that condition as
to whether or not we should override the interface value.

Pull regmap fix from Mark Brown:
"regmap: Fix handling of present bits on rbtree cache block resize
When expanding a cache block we use krealloc() to resize the register
present bitmap without initialising the newly allocated data (the
original code was written for kzalloc()). Add an appropraite memset()
to fix that"

regmap: regcache-rbtree: Clean new present bits on present bitmap resize
When creating dm-cache with the default policy, it will call
request_module("dm-cache-default") to register the default policy.
But the "dm-cache-default" alias was left referring to the MQ policy.
Fix this by moving the module alias to SMQ.
Fixes: bccab6a0 (dm cache: switch the "default" cache replacement policy from mq to smq)

When using nested btrees, the top leaves of the top levels contain
block addresses for the root of the next tree down. If we shadow a
shared leaf node the leaf values (sub tree roots) should be incremented
accordingly.
This is only an issue if there is metadata sharing in the top levels.
Which only occurs if metadata snapshots are being used (as is possible
with dm-thinp). And could result in a block from the thinp metadata
snap being reused early, thus corrupting the thinp metadata snap.

these modules use Kbuild for their names, they too need to be checked
by localmodconfig. This was fixed by Richard Weinberger.

Currently localmodconfig reads objects only from "Makefile"s and misses

Here's an important regression fix for the 4.2-rc series that ensures
user space isn't given invalid LTK values. The bug essentially prevents
the encryption of subsequent LE connections, i.e. makes it impossible to
pair devices over LE.
Let me know if there are any issues pulling. Thanks.

We are not interested in interrupts for partially transmitted frames.
Unlike SCC and FCC, the FEC doesn't handle the I bit in buffer
descriptors, instead it defines two interrupt bits, TXB and TXF.
We have to mask TXB in order to only get interrupts once the
frame is fully transmitted.

net: dsa: mv88e6xxx: support switchdev FDB objects
This patchset refactors the FDB management in the mv88e6xxx code and adds the
glue in DSA to use the switchdev FDB objects.
Below is an usage example (ports 0-2 belongs to br0, ports 3-4 belongs to br1):
# bridge fdb add 3c:97:0e:11:30:6e dev swp2
# bridge fdb add 3c:97:0e:11:40:78 dev swp3
# bridge fdb add 3c:97:0e:11:50:86 dev swp4
# bridge fdb del 3c:97:0e:11:40:78 dev swp3
# bridge fdb
01:00:5e:00:00:01 dev eth0 self permanent
01:00:5e:00:00:01 dev eth1 self permanent
00:50:d2:10:78:15 dev swp0 master br0 permanent
3c:97:0e:11:30:6e dev swp2 self static
00:50:d2:10:78:15 dev swp3 master br1 permanent
3c:97:0e:11:50:86 dev swp4 self static
# cat /sys/kernel/debug/dsa0/atu
# DB T/P Vec State Addr
# 001 Port 004 e 3c:97:0e:11:30:6e
# 004 Port 010 e 3c:97:0e:11:50:86
For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for non-bridged
ports and bridge groups, and the remaining will be later used by VLANs.
This change is necessary to welcome the support for hardware VLANs (which will
follow soon).
Changes in v3:
- reorder commits to improve bisectability and minimize diffs
- add an ndm_state member in switchdev_fdb_obj instead of an is_static boolean
- drop the need to convert unsigned char *addr to u8 addr[ETH_ALEN]
(it is casted to char pointer anyway)
Changes in v2:
- remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code
- use ether_addr_copy instead of memcpy for MAC addresses
- constify MAC address in port_fdb_{add,del}
- split the mv88e6xxx code refactoring into several patches
