mlx4 currently uses a too high tx coalescing setting, deferring TX completion interrupts by up to 128 us. With the recent skb_orphan() removal in commit 8112ec3b, performance of a single TCP flow is capped to ~4 Gbps, unless we increase tcp_limit_output_bytes. I suggest using 16 us instead of 128 us, allowing a finer control. Performance of a single TCP flow is restored to previous levels, while keeping TCP small queues fully enabled with default sysctl. This patch is also a BQL prereq.

On gcc 4.7, we will get alignment traps in the ip stack if we don't align the ip headers on receive. The h/w can support this, so use ip aligned allocations. Cut down the unnecessary padding on the allocation. The buffer can start on any byte alignment, but the size including the begining offset must be 8 byte aligned. So the h/w buffer size must include the NET_IP_ALIGN offset. Thanks to Eric Dumazet for the initial patch highlighting the padding issues.

Commit 56b765b7 (htb: improved accuracy at high rates) introduced two bugs : 1) one bstats_update() was inadvertently removed from htb_dequeue_tree(), breaking statistics/rate estimation. 2) Missing qdisc_put_rtab() calls in htb_change_class(), leaking kernel memory, now struct htb_class no longer retains pointers to qdisc_rate_table structs.

Building atp.o triggers this GCC warning: drivers/net/ethernet/realtek/atp.c: In function ‘set_rx_mode’: drivers/net/ethernet/realtek/atp.c:871:26: warning: ‘mc_filter[0]’ may be used uninitialized in this function [-Wuninitialized] GCC is correct. In promiscuous mode 'mc_filter' will be used uninitialized in set_rx_mode_8012(), which is apparently inlined into set_rx_mode(). But it turns out set_rx_mode_8012() will never be called, since net_local.chip_type will always be RTL8002. So we can just remove set_rx_mode_8012() and do some related cleanups.

When underlying phy driver restores its state very fast after being brought down and up so that macb driver function macb_handle_link_change() was never called with link state "down", driver's internal representation of phy speed and duplex (bp->speed and bp->duplex) didn't change. So, macb driver sees no reason to perform actual write to the NCFGR register, although the speed and duplex settings in that register were reset when interface was brought down and up. In that case actual phy speed and duplex differ from NCFGR settings. The patch fixes that by keeping internal driver representation of speed and duplex in sync with actual content of NCFGR.

Current HTB (and TBF) uses rate table computed by the "tc" userspace program, which has the following issue: The rate table has 256 entries to map packet lengths to token (time units). With TSO sized packets, the 256 entry granularity leads to loss/gain of rate, making the token bucket inaccurate. Thus, instead of relying on rate table, this patch explicitly computes the time and accounts for packet transmission times with nanosecond granularity. This greatly improves accuracy of HTB with a wide range of packet sizes. Example: tc qdisc add dev $dev root handle 1: \ htb default 1 tc class add dev $dev classid 1:1 parent 1: \ rate 5Gbit mtu 64k Here is an example of inaccuracy: $ iperf -c host -t 10 -i 1 With old htb: eth4: 34.76 Mb/s In 5827.98 Mb/s Out - 65836.0 p/s In 481273.0 p/s Out [SUM] 9.0-10.0 sec 669 MBytes 5.61 Gbits/sec [SUM] 0.0-10.0 sec 6.50 GBytes 5.58 Gbits/sec With new htb: eth4: 28.36 Mb/s In 5208.06 Mb/s Out - 53704.0 p/s In 430076.0 p/s Out [SUM] 9.0-10.0 sec 594 MBytes 4.98 Gbits/sec [SUM] 0.0-10.0 sec 5.80 GBytes 4.98 Gbits/sec The bits per second on the wire is still 5200Mb/s with new HTB because qdisc accounts for packet length using skb->len, which is smaller than total bytes on the wire if GSO is used. But that is for another patch regardless of how time is accounted. Many thanks to Eric Dumazet for review and feedback. Signed-off-by: NVimalkumar <j.vimal@gmail.com> Signed-off-by: NDavid S.
