net: eth: altera: Fix the initial device operstate

2015-09-09T19:10:15Z

Call netif_carrier_off() prior to register_netdev(), otherwise userspace can see incorrect link state. Signed-off-by: Atsushi Nemoto Signed-off-by: David S. Miller

net: eth: altera: fix napi poll_list corruption

2015-09-03T22:35:12Z

tse_poll() calls __napi_complete() with irq enabled. This leads napi poll_list corruption and may stop all napi drivers working. Use napi_complete() instead of __napi_complete(). Signed-off-by: Atsushi Nemoto Signed-off-by: David S. Miller

net: eth: altera: Remove sgdmadesclen member from altera_tse_private

2015-08-12T21:31:07Z

altera_tse_private->sgdmadesclen is always assigned assigned the same value and never changes during runtime. Remove the struct member and use a new define for sizeof(struct sgdma_descrip) instead. Signed-off-by: Tobias Klauser Signed-off-by: David S. Miller

altera_tse: Correct rx packet length

2015-04-29T19:19:34Z

Altera TSE MAC rx DMA transfer starts with the 2 additional bytes for IP payload alignment. This patch fixes tse_rx() function loop which reads DMA rx status and extracts packet length from it. Status signalises a whole DMA transfer length, which is 2 bytes longer than the packet itself. Signed-off-by: Vlastimil Setka Signed-off-by: David S. Miller

altera tse: add support for fixed-links.

2015-04-26T20:07:14Z

Add support for fixed-links in configurations without PHY. (e.g. connection to a switch, SGMII point to point, SFPs) Check: Documentation/devicetree/bindings/net/fixed-link.txt. Signed-off-by: Andreas Oetken Signed-off-by: David S. Miller

net: eth: altera: Resolve false errors from MSGDMA to TSE

2015-04-25T18:41:52Z

This patch resolves false errors from MSGDMA in TX mSGDMA MM to ST mode, and is a continuation of the patch recently submitted by Andrea Oetken. The MSGDMA had a logic bug that masked detection of this issue prior to Quartus 14.1/Build 164. When the MSGDMA logic bug was addressed in Quartus 14.1/Build 164, the driver problem was exposed. The problem is corrected by making sure MSGDMA_DESC_CTL_TR_ERR_IRQ is not set for any of the transmit DMA descriptors, and only used for receive descriptors. Fixes: 71cd26e altera tse: Error-Bit on tx-avalon-stream always set. Signed-off-by: Chee Nouk Phoon Signed-off-by: Vince Bridgers a Cc: Andreas Oetken Signed-off-by: David S. Miller

altera tse: Error-Bit on tx-avalon-stream always set.

2015-04-21T02:01:16Z

The Error-Bit on the avalon streaming interface of the tx-dma-channel was always set. In SGMII configurations this leads to error-symbols on the PCS and packet-rejection on the receiver side (e.g. SGMII/1000Base-X connected switch). This only applies to the tse-configuration with MSGDMA. This issue was detected and fixed on a custom board with a direct connection to a Marvell switch in SGMII-PHY-Mode. (incl. custom patches for SGMII-PCS). According to the datasheet if ff_tx_err (avalon-streaming) is set it is forwarded to gm_tx_err. As a result the PCS is forwarding the error by sending a "/V/"-caracter. Signed-off-by: Andreas Oetken Signed-off-by: David S. Miller

altera tse: Fix network-delays and -retransmissions after high throughput.

2015-04-17T19:13:31Z

Fix bug which occurs when more than packets are available during napi-poll, leading to "delays" and retransmissions on the network. Check for (count < limit) before checking the get_rx_status in tse_rx-function. Function get_rx_status is reading from the response-fifo. If there is currently a response in the fifo, reading the last byte of the response pops the value from the fifo. If the limit is checked as second condition and the limit is reached the fifo is popped but the packet is not processed. Signed-off-by: Andreas Oetken Signed-off-by: David S. Miller

Altera TSE: constify of_device_id array

2015-03-17T19:00:21Z

of_device_id is always used as const. (See driver.of_match_table and open firmware functions) Signed-off-by: Fabian Frederick Signed-off-by: David S. Miller

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2015-03-04T02:16:48Z

Conflicts: drivers/net/ethernet/rocker/rocker.c The rocker commit was two overlapping changes, one to rename the ->vport member to ->pport, and another making the bitmask expression use '1ULL' instead of plain '1'. Signed-off-by: David S. Miller
