bgmac: Utilize BRCM_PSEUDO_PHY_ADDR

2015-06-11T06:33:58Z

What BGMAC defines as BGMAC_PHY_NOREGS is in fact the Broadcom Ethernet switches' pseudo-PHY address (30), utilize the newly introduced constant from brcmphy.h Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

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: increase rx ring size from 511 to 512

2015-04-14T18:57:11Z

Limiting it to 511 looks like a failed attempt at leaving one descriptor empty to allow the hardware to stop processing a buffer that has not been prepared yet. However, this doesn't work because this affects the total ring size as well Signed-off-by: Felix Fietkau 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

bgmac: leave interrupts disabled as long as there is work to do

2015-04-14T18:57:10Z

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.

bgmac: simplify tx ring index handling

2015-04-14T18:57:10Z

Keep incrementing ring->start and ring->end instead of pointing it to the actual ring slot entry. This simplifies the calculation of the number of free slots. Signed-off-by: Felix Fietkau Acked-by: Rafał Miłecki Signed-off-by: David S. Miller

bgmac: implement GRO and use build_skb

2015-03-23T20:56:28Z

This improves performance for routing and local rx Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller

bgmac: fix descriptor frame start/end definitions

2015-03-23T20:56:28Z

The start-of-frame and end-of-frame bits were accidentally swapped. In the current code it does not make any difference, since they are always used together. Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller

bgmac: add support for Northstar SoC (BCM4707, BCM53018)

2014-01-05T01:25:20Z

This adds support for the Northstar SoC. This SoC does not have a PMU in bcma and no register on it should be called. In addition it support 2.5 GBit/s Ethernet to the PHY. This GMAC core is not fully working there are still problems with the DMA controller. Signed-off-by: Hauke Mehrtens Signed-off-by: David S. Miller

bgmac: add support for new BGMAC_CMDCFG_SR position on core rev >= 4

2014-01-05T01:25:19Z

The BGMAC_CMDCFG_SR register is at a different position on core rev >= 4 We do not know where this register is on a rev 5 or higher core, I have newer seen such a core. Signed-off-by: Hauke Mehrtens Acked-by: Rafał Miłecki Signed-off-by: David S. Miller
