Since commit 779d835e ("net: of_mdio: scan mdiobus for PHYs without reg property") we have two foreach loops which do pretty much the same thing. Factor the PHY device registration in a function helper: of_mdiobus_register_phy() which takes care of the details and allows for future PHY specific extensions. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e only. Christopher Pau provides a patch to set pf_id based on device and function numbers since NICs with ARI enabled can have function numbers larger than 8. Anjali provides 3 i40e patches to update hardware defines to keep in sync with hardware updates. Shannon provides the majority of i40e patches, with 7. First patch clears the admin queue head and tail registers during admin queue shutdown. Then simplifies the admin queue head-tail-len setups to use more virtual registers. Provides several patches to cleanup and fix driver load and reset procedures to make more robust. Lastly, provides an ethtool test for interrupts using the software interrupt. Mitch provides some i40e patches which fixes up VF code in the PF driver, specifically the number of vectors per VF are reported by the hardware does not include vector 0, so we need to account for this when checking. In addition, cleans up debugging messages. Kamil provides an i40e patch to fix the diagnostics test by restricting the diagnostic test length. ==================== Signed-off-by: -

John W. Linville says: ==================== Please pull this batch of updates intended for the 3.14 stream... For the mac80211 bits, Johannes says: "I have various improvements/cleanups/fixes all over, but the shortlog shows that Luis's regulatory work and mesh work from the cozybit folks are the biggest ones, along with the CSA fixes." Along with that, we have big batches of updates to brcmfmac, rtlwifi, and ath9k. There are updates to wcn36xx, rt2x00, and a handful of others as well. ==================== Signed-off-by: -

With the introduction of TCP Small Queues, TSO auto sizing, and TCP pacing, we can implement Automatic Corking in the kernel, to help applications doing small write()/sendmsg() to TCP sockets. Idea is to change tcp_push() to check if the current skb payload is under skb optimal size (a multiple of MSS bytes) If under 'size_goal', and at least one packet is still in Qdisc or NIC TX queues, set the TCP Small Queue Throttled bit, so that the push will be delayed up to TX completion time. This delay might allow the application to coalesce more bytes in the skb in following write()/sendmsg()/sendfile() system calls. The exact duration of the delay is depending on the dynamics of the system, and might be zero if no packet for this flow is actually held in Qdisc or NIC TX ring. Using FQ/pacing is a way to increase the probability of autocorking being triggered. Add a new sysctl (/proc/sys/net/ipv4/tcp_autocorking) to control this feature and default it to 1 (enabled) Add a new SNMP counter : nstat -a | grep TcpExtTCPAutoCorking This counter is incremented every time we detected skb was under used and its flush was deferred. Tested: Interesting effects when using line buffered commands under ssh. Excellent performance results in term of cpu usage and total throughput. lpq83:~# echo 1 >/proc/sys/net/ipv4/tcp_autocorking lpq83:~# perf stat ./super_netperf 4 -t TCP_STREAM -H lpq84 -- -m 128 9410.39 Performance counter stats for './super_netperf 4 -t TCP_STREAM -H lpq84 -- -m 128': 35209.439626 task-clock # 2.901 CPUs utilized 2,294 context-switches # 0.065 K/sec 101 CPU-migrations # 0.003 K/sec 4,079 page-faults # 0.116 K/sec 97,923,241,298 cycles # 2.781 GHz [83.31%] 51,832,908,236 stalled-cycles-frontend # 52.93% frontend cycles idle [83.30%] 25,697,986,603 stalled-cycles-backend # 26.24% backend cycles idle [66.70%] 102,225,978,536 instructions # 1.04 insns per cycle # 0.51 stalled cycles per insn [83.38%] 18,657,696,819 branches # 529.906 M/sec [83.29%] 91,679,646 branch-misses # 0.49% of all branches [83.40%] 12.136204899 seconds time elapsed lpq83:~# echo 0 >/proc/sys/net/ipv4/tcp_autocorking lpq83:~# perf stat ./super_netperf 4 -t TCP_STREAM -H lpq84 -- -m 128 6624.89 Performance counter stats for './super_netperf 4 -t TCP_STREAM -H lpq84 -- -m 128': 40045.864494 task-clock # 3.301 CPUs utilized 171 context-switches # 0.004 K/sec 53 CPU-migrations # 0.001 K/sec 4,080 page-faults # 0.102 K/sec 111,340,458,645 cycles # 2.780 GHz [83.34%] 61,778,039,277 stalled-cycles-frontend # 55.49% frontend cycles idle [83.31%] 29,295,522,759 stalled-cycles-backend # 26.31% backend cycles idle [66.67%] 108,654,349,355 instructions # 0.98 insns per cycle # 0.57 stalled cycles per insn [83.34%] 19,552,170,748 branches # 488.244 M/sec [83.34%] 157,875,417 branch-misses # 0.81% of all branches [83.34%] 12.130267788 seconds time elapsed Signed-off-by:Eric Dumazet <edumazet@google.com> Signed-off-by:
