bgmac: Update fixed_phy_register()

2015-09-02T18:39:58Z

Commit a5597008dbc2 ("phy: fixed_phy: Add gpio to determine link up/down.") added a new argument to fixed_phy_register(), but missed to update bgmac driver, causing the following build failure: drivers/net/ethernet/broadcom/bgmac.c:1450:2: error: too few arguments to function 'fixed_phy_register' Add the missing argument.

bgmac: support up to 3 cores (devices) on a bus

2015-08-27T18:28:40Z

Broadcom buses may have more than 1 Ethernet device. This is used e.g. to have few interfaces connected to different switch ports. So far we saw chipsets with only 2 devices (e.g. BCM4706) but recent ones have up to 3 (e.g. Netgear R8000 uses 3rd interface for most of switch traffic, lower interfaces are for some kind of offloading).

bgmac: fix requests for extra polling calls from NAPI

2015-04-24T15:31:27Z

After d75b1ade567f ("net: less interrupt masking in NAPI") polling function has to return whole budget when it wants NAPI to call it again.

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2015-04-17T19:50:54Z

Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS for Linux 4.1. Most noteworthy: - Add more Octeon-optimized crypto functions - Octeon crypto preemption and locking fixes - Little endian support for Octeon - Use correct CSR to soft reset Octeons - Support LEDs on the Octeon-based DSR-1000N - Fix PCI interrupt mapping for the Octeon-based DSR-1000N - Mark prom_free_prom_memory() as __init for a number of systems - Support for Imagination's Pistachio SOC. This includes arch and CLK bits. I'd like to merge pinctrl bits later - Improve parallelism of csum_partial for certain pipelines - Organize DTB files in subdirs like other architectures - Implement read_sched_clock for all MIPS platforms other than Octeon - Massive series of 38 fixes and cleanups for the FPU emulator / kernel - Further FPU remulator work to support new features. This sits on a separate branch which also has been pulled into the 4.1 KVM branch - Clean up and fixes for the SEAD3 eval board; remove unused file - Various updates for Netlogic platforms - A number of small updates for Loongson 3 platforms - Increase the memory limit for ATH79 platforms to 256MB - A fair number of fixes and updates for BCM47xx platforms - Finish the implementation of XPA support - MIPS FDC support. No, not floppy controller but Fast Debug Channel :) - Detect the R16000 used in SGI legacy platforms - Fix Kconfig dependencies for the SSB bus support" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (265 commits) MIPS: Makefile: Fix MIPS ASE detection code MIPS: asm: elf: Set O32 default FPU flags MIPS: BCM47XX: Fix detecting Microsoft MN-700 & Asus WL500G MIPS: Kconfig: Disable SMP/CPS for 64-bit MIPS: Hibernate: flush TLB entries earlier MIPS: smp-cps: cpu_set FPU mask if FPU present MIPS: lose_fpu(): Disable FPU when MSA enabled MIPS: ralink: add missing symbol for RALINK_ILL_ACC MIPS: ralink: Fix bad config symbol in PCI makefile.

bgmac: drop ring->num_slots

2015-04-14T18:57:11Z

The ring size is always known at compile time, so make the code a bit more efficient Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller

bgmac: fix DMA rx corruption

2015-04-14T18:57:11Z

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. Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller

bgmac: simplify dma init/cleanup

2015-04-14T18:57:11Z

Instead of allocating buffers at device init time and initializing descriptors at device open, do both at the same time (during open). Free all buffers when closing the device. Signed-off-by: Felix Fietkau Acked-by: Rafał Miłecki Signed-off-by: David S. Miller

bgmac: add check for oversized packets

2015-04-14T18:57:11Z

In very rare cases, the MAC can catch an internal buffer that is bigger than it's supposed to be. Instead of crashing the kernel, simply pass the buffer back to the hardware Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller

bgmac: simplify/optimize rx DMA error handling

2015-04-14T18:57:10Z

Allocate a new buffer before processing the completed one. If allocation fails, reuse the old buffer. Signed-off-by: Felix Fietkau Acked-by: Rafał Miłecki Signed-off-by: David S. Miller

bgmac: set received skb headroom to NET_SKB_PAD

2015-04-14T18:57:10Z

A packet buffer offset of 30 bytes is inefficient, because the first 2 bytes end up in a different cacheline. Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller
