drivers: net: xgene: fix ununiform latency across queues

2016-05-14T01:12:06Z

This patch addresses ununiform latency across queues by adding more queues to match with, upto number of CPU cores. Also, number of interrupts are increased and the channel numbers are reordered. Signed-off-by: Iyappan Subramanian Tested-by: Toan Le Signed-off-by: David S. Miller

drivers: net: xgene: fix sharing of irqs

2016-05-14T01:12:06Z

Since hardware doesn't allow sharing of interrupts, this patch fixes the same by removing IRQF_SHARED flag. Signed-off-by: Iyappan Subramanian Tested-by: Toan Le Signed-off-by: David S. Miller

xen-netback: fix extra_info handling in xenvif_tx_err()

2016-05-13T05:58:57Z

Patch 562abd39 "xen-netback: support multiple extra info fragments passed from frontend" contained a mistake which can result in an in- correct number of responses being generated when handling errors encountered when processing packets containing extra info fragments. This patch fixes the problem. Signed-off-by: Paul Durrant Reported-by: Jan Beulich Cc: Wei Liu Acked-by: Wei Liu Signed-off-by: David S. Miller

net: mvneta: bm: fix dependencies again

2016-05-12T20:56:30Z

I tried to fix this before, but my previous fix was incomplete and we can still get the same link error in randconfig builds because of the way that Kconfig treats the default y if MVNETA=y && MVNETA_BM_ENABLE line that does not actually trigger when MVNETA_BM_ENABLE=m, unlike I intended. Changing the line to use MVNETA_BM_ENABLE!=n however has the desired effect and hopefully makes all configurations work as expected.

bnxt_en: Add workaround to detect bad opaque in rx completion (part 2)

2016-05-12T03:46:09Z

Add detection and recovery code when the hardware returned opaque value does not match the expected consumer index. Once the issue is detected, we skip the processing of all RX and LRO/GRO packets. These completion entries are discarded without sending the SKB to the stack and without producing new buffers. The function will be reset from a workqueue.

bnxt_en: Add workaround to detect bad opaque in rx completion (part 1)

2016-05-12T03:46:09Z

There is a rare hardware bug that can cause a bad opaque value in the RX or TPA completion. When this happens, the hardware may have used the same buffer twice for 2 rx packets. In addition, the driver will also crash later using the bad opaque as the index into the ring. The rx opaque value is predictable and is always monotonically increasing. The workaround is to keep track of the expected next opaque value and compare it with the one returned by hardware during RX and TPA start completions. If they miscompare, we will not process any more RX and TPA completions and exit NAPI. We will then schedule a workqueue to reset the function. This patch adds the logic to keep track of the next rx consumer index. Signed-off-by: Michael Chan Signed-off-by: David S. Miller

qlcnic: potential NULL dereference in qlcnic_83xx_get_minidump_template()

2016-05-12T03:44:56Z

If qlcnic_fw_cmd_get_minidump_temp() fails then "fw_dump->tmpl_hdr" is NULL or possibly freed. It can lead to an oops later. Fixes: d01a6d3c8ae1 ('qlcnic: Add support to enable capability to extend minidump for iSCSI') Signed-off-by: Dan Carpenter Signed-off-by: David S. Miller
