2016-11-16amd-xgbe: Fix possible uninitialized variableLendacky, Thomas1-1/+1
The debugfs support in the driver uses a common routine to write the debugfs values. In this routine, if the input file position is non-zero then the write routine will not return an error and an output parameter will not have been set. Because an error isn't returned an uninitialized value will be written into a register. Fix the common write routine to return an error if the input file position is non-zero, which will propagate back to the caller.

2016-11-16net: busy-poll: return busypolling status to driversEric Dumazet2-7/+10
NAPI drivers use napi_complete_done() or napi_complete() when they drained RX ring and right before re-enabling device interrupts. In busy polling, we can avoid interrupts being delivered since we are polling RX ring in a controlled loop. Drivers can chose to use napi_complete_done() return value to reduce interrupts overhead while busy polling is active. This is optional, legacy drivers should work fine even if not updated.

2016-11-16net: busy-poll: allow preemption in sk_busy_loop()Eric Dumazet2-20/+92
After commit 4cd13c21b207 ("softirq: Let ksoftirqd do its job"), sk_busy_loop() needs a bit of care : softirqs might be delayed since we do not allow preemption yet. This patch adds preemptiom points in sk_busy_loop(), and makes sure no unnecessary cache line dirtying or atomic operations are done while looping. A new flag is added into napi->state : NAPI_STATE_IN_BUSY_POLL This prevents napi_complete_done() from clearing NAPIF_STATE_SCHED, so that sk_busy_loop() does not have to grab it again. Similarly, netpoll_poll_lock() is done one time. This gives about 10 to 20 % improvement in various busy polling tests, especially when many threads are busy polling in configurations with large number of NIC queues. This should allow experimenting with bigger delays without hurting overall latencies. Tested: On a 40Gb mlx4 NIC, 32 RX/TX queues. echo 70 >/proc/sys/net/core/busy_read for i in `seq 1 40`; do echo -n $i: ; ./super_netperf $i -H lpaa24 -t UDP_RR -- -N -n; done Before: After: 1: 90072 92819 2: 157289 184007 3: 235772 213504 4: 344074 357513 5: 394755 458267 6: 461151 487819 7: 549116 625963 8: 544423 716219 9: 720460 738446 10: 794686 837612 11: 915998 923960 12: 937507 925107 13: 1019677 971506 14: 1046831 1113650 15: 1114154 1148902 16: 1105221 1179263 17: 1266552 1299585 18: 1258454 1383817 19: 1341453 1312194 20: 1363557 1488487 21: 1387979 1501004 22: 1417552 1601683 23: 1550049 1642002 24: 1568876 1601915 25: 1560239 1683607 26: 1640207 1745211 27: 1706540 1723574 28: 1638518 1722036 29: 1734309 1757447 30: 1782007 1855436 31: 1724806 1888539 32: 1717716 1944297 33: 1778716 1869118 34: 1805738 1983466 35: 1815694 2020758 36: 1893059 2035632 37: 1843406 2034653 38: 1888830 2086580 39: 1972827 2143567 40: 1877729 2181851 Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Willem de Bruijn <willemb@google.com> Cc: Adam Belay <abelay@google.com> Cc: Tariq Toukan <tariqt@mellanox.com> Cc: Yuval Mintz <Yuval.Mintz@cavium.com> Cc: Ariel Elior <ariel.elior@cavium.com> Signed-off-by: David S.

The EMAC EMAC_RX_IO_DATA_REG data register is dual-purpose: On one hand it is used to move actual packet data off the wire. This will be in wire-format and accepted as such by higher layers such as IP. Therefore it is correctly read as-is (i.e. raw) using readsl. On the other hand it provides metadata about incoming transfers to the driver such as length and checksum validation status. This data is little-endian, always and it is interpreted by the driver. Therefore it needs to be swapped to CPU endianness to make sense to the driver. This is already done for the "receive header" but not rxhdr. Read rxhdr using readl in order for sun4i-emac to work correctly when running a big-endian kernel.

2016-11-15net: ethernet: stmmac: change dma descriptors to __le32Michael Weiser8-181/+195
The stmmac driver does not take into account the processor may be big endian when writing the DMA descriptors. This causes the ethernet interface not to be initialised correctly when running a big-endian kernel. Change the descriptors for DMA to use __le32 and ensure they are suitably swapped before writing. Tested successfully on the Cubieboard2.

2016-11-15dctcp: update cwnd on congestion eventFlorian Westphal1-1/+8
draft-ietf-tcpm-dctcp-02 says: ... when the sender receives an indication of congestion (ECE), the sender SHOULD update cwnd as follows: cwnd = cwnd * (1 - DCTCP.Alpha / 2) So, lets do this and reduce cwnd more smoothly (and faster), as per current congestion estimate.
