Subject: [PATCH] MIPS: BCM47xx: Move NVRAM header to the include/linux/.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are two reasons for having this header in the common place:
1) Simplifying drivers that read NVRAM entries. We will be able to
safely call bcm47xx_nvram_* functions without #ifdef-s.
2) Getting NVRAM driver out of MIPS arch code. This is needed to support
BCM5301X arch which also requires this NVRAM driver. Patch for that
will follow once we get is reviewed.

Subject: [PATCH] MIPS: BCM47XX: Increase NVRAM buffer size to 64 KiB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
For years Broadcom devices use 64 KiB NVRAM partition size and some of
them indeed have it filled in more than 50%. This change allows reading
whole NVRAM e.g. on Netgear WNDR4500 and Netgear R8000.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When dealing with whole flash content (bcm47xx_nvram_init_from_mem) we
need to find NVRAM start trying various partition sizes (nvram_sizes).
This is not needed when using MTD as we have direct partition access.

Subject: [PATCH] MIPS: BCM47xx: Add generic function filling SPROM entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Handling many SPROM revisions became messy, we have tons of functions
specific to various revision groups which are quite hard to track.
For years there is yet another revision 11 asking for support, but
adding it in current the form would make things even worse.
To resolve this problem let's add new function with table-like entries
that will contain revision bitmask for every SPROM variable.

Subject: [PATCH] MIPS: BCM47xx: Move filling most of SPROM to the generic
function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This simplifies code a lot by dropping many per-revision-group
functions. There are still some paths left that use uncommon NVRAM read
helpers or fill arrays. They will need to be handled in separated patch.
I've tested this (by printing SPROM content) for regressions on:
1) BCM4704 (SPROM revision 2)
2) BCM4706 (SPROM revision 8 plus 11 & 9 on extra WiFi cards)
The only difference is not reading board_type from SPROM rev 11 which is
unsupported and treated as rev 1. This change for rev 1 is expected.

Subject: [PATCH] MIPS: BCM47XX: Simplify function looking for NVRAM entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
First of all it shouldn't modify copied NVRAM just to make sure it can
loop over all entries. It's enough to just compare current position
pointer with the end of buffer address.
Secondly buffer is guaranteed to be \0 ended, so we don't need strnchr.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
For years we planned to get rid of old u16 fields, let's start doing it
with MIPS code. This process will take some time, it requires doing the
same in ssb/bcma and then switching all drivers to new fields. This will
be handled in separated patches submitted to appropriate trees.

Extra bcma buses may be totally different models, see following dump:
boardtype=0x0646
pci/1/1/boardtype=0x0545
pci/2/1/boardtype=0x62b
We need to detect them properly to allow drivers apply some board
specific hacks.

Subject: [PATCH] MIPS: BCM77xx: Remove legacy __cpuinit{,data} sections that
crept in
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We removed __cpuinit support (leaving no-op stubs) quite some time ago.
However a few more crept in as of commit 6ee1d93455384cef8a0426effe85da2
("MIPS: BCM47XX: Detect more then 128 MiB of RAM (HIGHMEM)")
Since we want to clobber the stubs soon, get this removed now.

Host platforms such as routers supported by OpenWrt can
support NVRAM reading directly from internal NVRAM store.
The brcmfmac for one requires the complete nvram contents
to select what needs to be sent to wireless device.

Subject: [PATCH] MIPS: BCM47xx: Add helper variable for storing NVRAM length
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This simplifies code just a bit (also maybe makes it a bit more
intuitive?) and will allow us to stop storing header. Right now we copy
whole NVRAM including its header to the internal buffer. It is not
needed to store a header as we don't access all these details like CRC,
flags, etc. The next improvement that should follow is copying only the
real contents.

Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If SoC has a CardBus we can set resources of device at slot 1 only. It's
impossigle to set bridge resources as it simply overwrites device 1
configuration and usually results in Data bus error-s.

Subject: netfilter: conntrack: cache route for forwarded connections
... to avoid per-packet FIB lookup if possible.
The cached dst is re-used provided the input interface
is the same as that of the previous packet in the same direction.
If not, the cached dst is invalidated.
For ipv6 we also need to store sernum, else dst_check doesn't work,
pointed out by Eric Dumazet.
This should speed up forwarding when conntrack is already in use
anyway, especially when using reverse path filtering -- active RPF
enforces two FIB lookups for each packet.
Before the routing cache removal this didn't matter since RPF was performed
only when route cache didn't yield a result; but without route cache it
comes at higher price.
Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
avoid holding on to dsts of 'frozen' conntracks.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On ARM SoCs with bgmac Ethernet hardware we don't have any normal PHY.
There is always a switch attached but it's not even controlled over MDIO
like in case of MIPS devices.
We need a fixed PHY to be able to send/receive packets from the switch.

Subject: [PATCH] bgmac: implement scatter/gather support
Always use software checksumming, since the hardware does not have any
checksum offload support.
This significantly improves local TCP tx performance.

Subject: [PATCH] bgmac: leave interrupts disabled as long as there is work
to do
Always poll rx and tx during NAPI poll instead of relying on the status
of the first interrupt. This prevents bgmac_poll from leaving unfinished
work around until the next IRQ.
In my tests this makes bridging/routing throughput under heavy load more
stable and ensures that no new IRQs arrive as long as bgmac_poll uses up
the entire budget.

Subject: [PATCH] bgmac: set received skb headroom to NET_SKB_PAD
A packet buffer offset of 30 bytes is inefficient, because the first 2
bytes end up in a different cacheline.

Subject: [PATCH] bgmac: fix DMA rx corruption
The driver needs to inform the hardware about the first invalid (not yet
filled) rx slot, by writing its DMA descriptor pointer offset to the
BGMAC_DMA_RX_INDEX register.
This register was set to a value exceeding the rx ring size, effectively
allowing the hardware constant access to the full ring, regardless of
which slots are initialized.
To fix this issue, always mark the last filled rx slot as invalid.

Subject: [PATCH] pppoe: Use workqueue to die properly when a PADT is received
When a PADT frame is received, the socket may not be in a good state to
close down the PPP interface. The current implementation handles this by
simply blocking all further PPP traffic, and hoping that the lack of traffic
will trigger the user to investigate.
Use schedule_work to get to a process context from which we clear down the
PPP interface, in a fashion analogous to hangup on a TTY-based PPP
interface. This causes pppd to disconnect immediately, and allows tools to
take immediate corrective action.
Note that pppd's rp_pppoe.so plugin has code in it to disable the session
when it disconnects; however, as a consequence of this patch, the session is
already disabled before rp_pppoe.so is asked to disable the session. The
result is a harmless error message:
Failed to disconnect PPPoE socket: 114 Operation already in progress
This message is safe to ignore, as long as the error is 114 Operation
already in progress; in that specific case, it means that the PPPoE session
has already been disabled before pppd tried to disable it.

Subject: bridge: allow receiption on disabled port
When an ethernet device is enslaved to a bridge, and the bridge STP
detects loss of carrier (or operational state down), then normally
packet receiption is blocked.
This breaks control applications like WPA which maybe expecting to
receive packets to negotiate to bring link up. The bridge needs to
block forwarding packets from these disabled ports, but there is no
hard requirement to not allow local packet delivery.

Several DMA ops are no-op on many platforms, and the indirection through
the mips_dma_map_ops function table is causing the compiler to emit
unnecessary code.
Inlining visibly improves network performance in my tests (on a 24Kc
