Nikolay Aleksandrov says: ==================== This is a complete remake of my old patch that modified the bonding hash functions to use skb_flow_dissect which was suggested by Eric Dumazet. This time around I've left the old modes although using a new hash function again suggested by Eric, which is the same for all modes. The only difference is the way the headers are obtained. The old modes obtain them as before in order to address concerns about speed, but the 2 new ones use skb_flow_dissect. The unification of the hash function allows to remove a pointer from struct bonding and also a few extra functions that dealt with it. Two new functions are added which take care of the hashing based on bond->params.xmit_policy only: bond_xmit_hash() - global function, used by XOR and 3ad modes bond_flow_dissect() - used by bond_xmit_hash() to obtain the necessary headers and combine them according to bond->params.xmit_policy. Also factor out the ports extraction from skb_flow_dissect and add a new function - skb_flow_get_ports() which can be re-used. v2: add the flow_dissector patch and use skb_flow_get_ports in patch 02 v3: fix a bug in the flow_dissector patch that caused a different thoff by modifying the thoff argument in skb_flow_get_ports directly, most of the users already do it anyway. Also add the necessary export symbol for skb_flow_get_ports. v4: integrate the thoff bug fix in patch 01 v5: disintegrate the thoff bug fix and re-base on top of Eric's fix ==================== Signed-off-by: -

This patch adds two new hash policy modes which use skb_flow_dissect: 3 - Encapsulated layer 2+3 4 - Encapsulated layer 3+4 There should be a good improvement for tunnel users in those modes. It also changes the old hash functions to: hash ^= (__force u32)flow.dst ^ (__force u32)flow.src; hash ^= (hash >> 16); hash ^= (hash >> 8); Where hash will be initialized either to L2 hash, that is SRCMAC[5] XOR DSTMAC[5], or to flow->ports which should be extracted from the upper layer. Flow's dst and src are also extracted based on the xmit policy either directly from the buffer or by using skb_flow_dissect, but in both cases if the protocol is IPv6 then dst and src are obtained by ipv6_addr_hash() on the real addresses. In case of a non-dissectable packet, the algorithms fall back to L2 hashing. The bond_set_mode_ops() function is now obsolete and thus deleted because it was used only to set the proper hash policy. Also we trim a pointer from struct bonding because we no longer need to keep the hash function, now there's only a single hash function - bond_xmit_hash that works based on bond->params.xmit_policy. The hash function and skb_flow_dissect were suggested by Eric Dumazet. The layer names were suggested by Andy Gospodarek, because I suck at semantics. Signed-off-by:

TCP listener refactoring, part 2 : We can use a generic lookup, sockets being in whatever state, if we are sure all relevant fields are at the same place in all socket types (ESTABLISH, TIME_WAIT, SYN_RECV) This patch removes these macros : inet_addrpair, inet_addrpair, tw_addrpair, tw_portpair And adds : sk_portpair, sk_addrpair, sk_daddr, sk_rcv_saddr Then, INET_TW_MATCH() is really the same than INET_MATCH() Signed-off-by:

tcp_fixup_sndbuf() is underestimating initial send buffer requirements. It was not noticed because big GSO packets were escaping the limitation, but with smaller TSO packets (or TSO/GSO/SG off), application hits sk_sndbuf before having a chance to fill enough packets in socket write queue. - initial cwnd can be bigger than 10 for specific routes - SKB_TRUESIZE() is a bit under real needs in some cases, because of power-of-two rounding in kmalloc() - Fast Recovery (RFC 5681 3.2) : Cubic needs 70% factor - Extra cushion (application might react slowly to POLLOUT) tcp_v4_conn_req_fastopen() needs to call tcp_init_metrics() before calling tcp_init_buffer_space() Then we realize tcp_new_space() should call tcp_fixup_sndbuf() instead of duplicating this stuff. Rename tcp_fixup_sndbuf() to tcp_sndbuf_expand() to be more descriptive. Signed-off-by:

Because 'node' is the i'st child of 'oldnode', thus, here 'i' equals tkey_extract_bits(node->key, oldtnode->pos, oldtnode->bits) we just get 1 more bit, and need not care the detail value of this bits.

When phylib was in use tg3 only searched at address 01 on the mdio bus and did not work with any other address. On the BCM4705 SoCs the switch is connected as a PHY behind the MAC driven by tg3 and it is at PHY address 30 in most cases. This is a preparation patch to allow support for such switches. phy_addr is set to TG3_PHY_MII_ADDR for all devices, which are using phylib, so this should not change any behavior. Signed-off-by:

FQ rate limiting suffers from two problems, reported by Steinar : 1) FQ enforces a delay when flow quantum is exhausted in order to reduce cpu overhead. But if packets are small, current delay computation is slightly wrong, and observed rates can be too high. Steinar had this problem because he disabled TSO and GSO, and default FQ quantum is 2*1514. (Of course, I wish recent TSO auto sizing changes will help to not having to disable TSO in the first place) 2) maxrate was not used for forwarded flows (skbs not attached to a socket) Tested: tc qdisc add dev eth0 root est 1sec 4sec fq maxrate 8Mbit netperf -H lpq84 -l 1000 & sleep 10 ; tc -s qdisc show dev eth0 qdisc fq 8003: root refcnt 32 limit 10000p flow_limit 100p buckets 1024 quantum 3028 initial_quantum 15140 maxrate 8000Kbit Sent 16819357 bytes 11258 pkt (dropped 0, overlimits 0 requeues 0) rate 7831Kbit 653pps backlog 7570b 5p requeues 0 44 flows (43 inactive, 1 throttled), next packet delay 2977352 ns 0 gc, 0 highprio, 5545 throttled lpq83:~# tcpdump -p -i eth0 host lpq84 -c 12 09:02:52.079484 IP lpq83 > lpq84: . 1389536928:1389538376(1448) ack 3808678021 win 457 <nop,nop,timestamp 961812 572609068> 09:02:52.079499 IP lpq83 > lpq84: . 1448:2896(1448) ack 1 win 457 <nop,nop,timestamp 961812 572609068> 09:02:52.079906 IP lpq84 > lpq83: . ack 2896 win 16384 <nop,nop,timestamp 572609080 961812> 09:02:52.082568 IP lpq83 > lpq84: . 2896:4344(1448) ack 1 win 457 <nop,nop,timestamp 961815 572609071> 09:02:52.082581 IP lpq83 > lpq84: . 4344:5792(1448) ack 1 win 457 <nop,nop,timestamp 961815 572609071> 09:02:52.083017 IP lpq84 > lpq83: . ack 5792 win 16384 <nop,nop,timestamp 572609083 961815> 09:02:52.085678 IP lpq83 > lpq84: . 5792:7240(1448) ack 1 win 457 <nop,nop,timestamp 961818 572609074> 09:02:52.085693 IP lpq83 > lpq84: . 7240:8688(1448) ack 1 win 457 <nop,nop,timestamp 961818 572609074> 09:02:52.086117 IP lpq84 > lpq83: . ack 8688 win 16384 <nop,nop,timestamp 572609086 961818> 09:02:52.088792 IP lpq83 > lpq84: . 8688:10136(1448) ack 1 win 457 <nop,nop,timestamp 961821 572609077> 09:02:52.088806 IP lpq83 > lpq84: . 10136:11584(1448) ack 1 win 457 <nop,nop,timestamp 961821 572609077> 09:02:52.089217 IP lpq84 > lpq83: . ack 11584 win 16384 <nop,nop,timestamp 572609090 961821> Reported-by:

Jeff Kirsher says: ==================== This series contains updates to ixgbevf, ixgbe and igb. Don provides 3 patches for ixgbevf where he cleans up a redundant read mailbox failure check, adds a new function to wait for receive queues to be disabled before disabling NAPI, and move the API negotiation so that it occurs in the reset path. This will allow the PF to be informed of the API version earlier. Jacob provides a ixgbevf and ixgbe patch. His ixgbevf patch removes the use of hw_dbg when the ixgbe_get_regs function is called in ethtool. The ixgbe patch renames the LL_EXTENDED_STATS and some of the functions required to implement busy polling in order to remove the marketing "low latency" blurb which hides what the code actually does. Leonardo provides a ixgbe patch to add support for DCB registers dump using ethtool for 82599 and x540 ethernet controllers. I (Jeff) provide a ixgbe patch to cleanup whitespace issues seen in a code review. Todd provides for igb to add support for i354 in the ethtool offline tests. Laura provides an igb patch to add the ethtool callbacks necessary to configure the number of RSS queues. ==================== Signed-off-by: -

After this patch the API negotiation will occur in the reset path. So now the PF will be informed of the API version earlier. This will also require the mailbox lock to be initialize sooner as well. Signed-off-by:

New function was added to wait for Rx queues to be disabled before disabling NAPI. This function also allows us to modify ixgbevf_rx_desc_queue_enable() to better match ixgbe. I also cleaned up some msleep calls to usleep_range while I was in this code anyway. Signed-off-by:

Since we are already checking for read failure in check_link we don't need to do it here. Instead just make sure the watchdog task gets scheduled, if we are up, and it can be done there. This will better follow igbvf method of handling a mailbox event and message timeout. Signed-off-by:

This patch removes the use of hw_dbg in ixgbevf when the ixgbe_get_regs function is called from ethtool. This goes along side a patch to ethtool which enables proper support for ixgbevf pretty-printing of registers. Signed-off-by:

In the xmit path, the driver may drop some pkts due to reasons such as DMA mapping errors, out of memory conditions or to protect HW from unrecoverable errors. Add a counter in TX-stats for such drops. Signed-off-by:

The current EQ delay calculation for AIC is based only on RX packet rate. This fails to be effective when there's only TX and no RX. This patch inclues: - Calculating EQ-delay based on both RX and TX pps. - Modifying EQ-delay of all EQs via one cmd, instead of issuing a separate cmd for each EQ. - A new structure to store interrupt coalescing parameters, in a separate cache-line from the EQ-obj.

This cmd needs to be sent to FW when enabling VFs (currently used only for Lancer.) Also, avoid calling the cmd when driver loads and finds that VFs are already enabled from a previous load. Signed-off-by:

On BE3-R 1G ports (identified by port numbers 2 and 3) the FW cannot properly support multiple TXQs. This also makes the number of RX and TX queues symmetric as only a single RXQ is available on 1G ports. Signed-off-by:
