-Subject: [PATCH] MIPS: lantiq: enable all hardware interrupts on second VPE
-
-This patch is needed to handle interrupts by the second VPE on the Lantiq
-ARX100, xRX200, xRX300 and xRX330 SoCs. Switching some ICU interrupts to
-the second VPE results in a hang. Currently, the vsmp_init_secondary()
-function is responsible for enabling these interrupts. It only enables
-Malta-specific interrupts (SW0, SW1, HW4 and HW5).
-
-The MIPS core has 8 interrupts defined. On Lantiq SoCs, hardware
-interrupts are wired to an ICU instance. Each VPE has an independent
-instance of the ICU. The mapping of the ICU interrupts is shown below:
-SW0(IP0) - IPI call,
-SW1(IP1) - IPI resched,
-HW0(IP2) - ICU 0-31,
-HW1(IP3) - ICU 32-63,
-HW2(IP4) - ICU 64-95,
-HW3(IP5) - ICU 96-127,
-HW4(IP6) - ICU 128-159,
-HW5(IP7) - timer.
-
-This patch enables all interrupt lines on the second VPE.
-
-This problem affects multithreaded SoCs with a custom interrupt controller.
-SOCs with 1004Kc core and newer use the MIPS GIC. At this point, I am aware
-that the Realtek RTL839x and RTL930x SoCs may need a similar fix. In the
-future, this may be replaced with some generic solution.
-
-Tested on Lantiq xRX200.

-Subject: [PATCH] net: lantiq_xrx200: increase buffer reservation
-
-If the user sets a lower mtu on the CPU port than on the switch,
-then DMA inserts a few more bytes into the buffer than expected.
-In the worst case, it may exceed the size of the buffer. The
-experiments showed that the buffer should be a multiple of the
-burst length value. This patch rounds the length of the rx buffer
-upwards and fixes this bug. The reservation of FCS space in the
-buffer has been removed as PMAC strips the FCS.

-Subject: [PATCH] net: lantiq_xrx200: add ingress SG DMA support
-
-This patch adds support for scatter gather DMA. DMA in PMAC splits
-the packet into several buffers when the MTU on the CPU port is
-less than the MTU of the switch. The first buffer starts at an
-offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the
-offset. Thanks to this patch, the user can still connect to the
-device in such a situation. For normal configurations, the patch
-has no effect on performance.

-
-This enables non-standard MTUs on a per-port basis, with the overall
-frame size set based on the CPU port.
-
-When the MTU is not changed, this should have no effect.
-
-Long packets crash the switch with MTUs of greater than 2526, so the
-maximum is limited for now. Medium packets are sometimes dropped (e.g.
-TCP over 2477, UDP over 2516-2519, ICMP over 2526), Hence an MTU value
-of 2400 seems safe.

-
-Configure the burst length in Ethernet drivers. This improves
-Ethernet performance by 58%. According to the vendor BSP,
-8W burst length is supported by ar9 and newer SoCs.
-
-The NAT benchmark results on xRX200 (Down/Up):
-* 2W: 330 Mb/s
-* 4W: 432 Mb/s 372 Mb/s
-* 8W: 520 Mb/s 389 Mb/s
-
-Tested on xRX200 and xRX330.

-
-When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll
-function immediately returns an error.
-This is incorrect for two reasons:
-* the function terminates without enabling interrupts or scheduling NAPI,
-* the error code (-ENOMEM) is returned instead of the number of received
-packets.
-
-After the first memory allocation failure occurs, packet reception is
-locked due to disabled interrupts from DMA..
