+Subject: [PATCH] ARM: dts: BCM5301X: Explicitly disable unused switch CPU
+ ports
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When redescribing ports I assumed that missing "label" (like "cpu")
+means switch port isn't used. That was incorrect and I realized my
+change made Linux always use the first (5) CPU port (there are 3 of
+them).
+
+While above should technically be possible it often isn't correct:
+1. Non-default switch ports are often connected to Ethernet interfaces
+   not fully covered by vendor setup (they may miss MACs)
+2. On some devices non-default ports require specifying fixed link
+
+This fixes network connectivity for some devices. It was reported &
+tested for Netgear R8000. It also affects Linksys EA9200 with its
+downstream DTS.
+
+Fixes: ba4aebce23b2 ("ARM: dts: BCM5301X: Describe switch ports in the main DTS")

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Ports 5 and 7 are disabled by default because the standard use case is
+for port 8 to manage all CPU directed traffic. For experimentation
+purposes however it is desirable to provide adequate properties such
+that people can experiment with using different ports without having to
+figure out their configuration. Some of the use cases include but are
+not limited to doubling or tripling the bandwidth by leveraging the
+additional ports/Ethernet MAC combinations.

+Parsing every partition with "compatible" set to "brcm,trx" results in

+
+partition@200000 {

+	compatible = "linksys,ns-firmware", "brcm,trx";
+};
+
+Check for MTD partition name "firmware" before parsing. Recently added
+ofpart_linksys_ns.c creates "firmware" and "failsafe" depending on
+bootloader setup.

+Subject: [PATCH] usb: xhci: add support for performing fake doorbell
+
+Broadcom's Northstar XHCI controllers seem to need a special start
+procedure to work correctly. There isn't any official documentation of
+this, the problem is that controller doesn't detect any connected
+devices with default setup. Moreover connecting USB device to controller
+that doesn't run properly can cause SoC's watchdog issues.
+
+A workaround that was successfully tested on multiple devices is to
+perform a fake doorbell. This patch adds code for doing this and enables
+it on BCM4708 family.

+Subject: [PATCH] ARM: BCM5301X: Disable MMU and Dcache during decompression
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Broadcom devices have broken CFE (bootloader) that leaves hardware in an
+invalid state. It causes problems with booting Linux. On Northstar
+devices kernel was randomly hanging in ~25% of tries during early init.
+Hangs used to happen at random places in the start_kernel. On BCM53573
+kernel doesn't even seem to start booting.
+
+To workaround this problem we need to do following very early:
+1) Clear 2 following bits in the SCTLR register:
+#define CR_M    (1 << 0)        /* MMU enable */
+#define CR_C    (1 << 2)        /* Dcache enable */
+2) Flush the whole D-cache
+3) Disable L2 cache
+
+Unfortunately this patch is not upstreamable as it does above things
+unconditionally. We can't check if we are running on Broadcom platform
+in any safe way and doing such hacks with ARCH_MULTI_V7 is unacceptable
+as it could break other devices support.

+Subject: [PATCH] bcm53xx: partition fixups for Meraki MX64/MX65
+
+We need to enlarge the u-boot partition to add extra features like UBI
+booting. The shmoo and newly created env partitions can easily be moved
+to the nvram partition. This fixup allows u-boot to be enlarged to up to
+1MiB.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In many cases GRO improves network performance however it comes at a
+cost of chacksums calculations. In case of slow CPU and missing hardware
+csum calculation support GRO can actually decrease network speed.
+
+On BCM4708 *disabling* GRO results in following NAT masquarade speed
+changes:
+1. 364 Mb/s → 396 Mb/s (packet steering disabled)
+2. 341 Mb/s → 566 Mb/s (packet steering enabled)

+Subject: [PATCH] bgmac: reduce max frame size to support just MTU 1500
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+bgmac allocates new replacement buffer before handling each received
+frame. Allocating & DMA-preparing 9724 B each time consumes a lot of CPU
+time. Ideally bgmac should just respect currently set MTU but it isn't
+the case right now. For now just revert back to the old limited frame
+size.
+
+This change bumps NAT masquarade speed by ~95%.
