don't clone skb when skb isn't shared When the tcf_action is TC_ACT_STOLEN, and the skb isn't shared, we don't need to clone a new skb. As the skb will be freed after this function returns, we can use it freely once we get a reference to it. Signed-off-by:

Currently much of the code assumes that a specific window has been selected, while a few functions save and restore the window. This makes it impossible to introduce fine-grained locking. Make those assumptions explicit by introducing wrapper functions to set the window and read/write a register. Use these everywhere except vortex_interrupt(), vortex_start_xmit() and vortex_rx(). These set the window just once, or not at all in the case of vortex_rx() as it should always be called from vortex_interrupt(). Cache the current window in struct vortex_private to avoid unnecessary hardware writes. Signed-off-by:

This patch adds dynamic LRO diable support for mlx4 net driver. It also fixes a bug of mlx4, which checks NETIF_F_LRO flag in rx path without rtnl lock. (I don't have mlx4 card, so only did compiling test. Anyone who wants to test this is more than welcome.) This is based on Neil's initial work too, and heavily modified based on Stanislaw's suggestions. Signed-off-by:

This patch adds dynamic LRO disable support for s2io net driver, enables LRO by default, increases the driver version number, and corrects the name of the LRO modparm. This is mostly Wang's patch based on Neil's initial work, heavily modified based on Ramkrishna's suggestions. This has been tested on a Neterion Xframe adapter and verified via adapter LRO statistics. Signed-off-by:

As pointed out by Fernando Gont there is no need to encode rcv_wscale into the cookie. We did not use the restored rcv_wscale anyway; it is recomputed via tcp_select_initial_window(). Thus we can save 4 bits in the ts option space by removing rcv_wscale. In case window scaling was not supported, we set the (invalid) wscale value 0xf. Signed-off-by:

This patch is thanks to Andre Noll who reported the issue and helped testing. The Syn-RTT sampled during the initial handshake currently only works for the client sending the DCCP-Request. TFRC penalizes the absence of an RTT sample with a very slow initial speed (1 packet per second), which delays slow-start significantly, resulting in sluggish performance. This patch mirrors the "Syn RTT" principle by adding a timestamp also onto the DCCP-Response, producing an RTT sample when the (Data)Ack completing the handshake arrives. Also changed the documentation to 'TFRC' since Syn RTTs are also used by CCID-4. Signed-off-by:

Gcc is currenlty not in the ability to optimize the switch statement in sk_run_filter() because of dense case labels. This patch replace the OR'd labels with ordered sequenced case labels. The sk_chk_filter() function is modified to patch/replace the original OPCODES in a ordered but equivalent form. gcc is now in the ability to transform the switch statement in sk_run_filter into a jump table of complexity O(1). Until this patch gcc generates a sequence of conditional branches (O(n) of 567 byte .text segment size (arch x86_64): 7ff: 8b 06 mov (%rsi),%eax 801: 66 83 f8 35 cmp $0x35,%ax 805: 0f 84 d0 02 00 00 je adb <sk_run_filter+0x31d> 80b: 0f 87 07 01 00 00 ja 918 <sk_run_filter+0x15a> 811: 66 83 f8 15 cmp $0x15,%ax 815: 0f 84 c5 02 00 00 je ae0 <sk_run_filter+0x322> 81b: 77 73 ja 890 <sk_run_filter+0xd2> 81d: 66 83 f8 04 cmp $0x4,%ax 821: 0f 84 17 02 00 00 je a3e <sk_run_filter+0x280> 827: 77 29 ja 852 <sk_run_filter+0x94> 829: 66 83 f8 01 cmp $0x1,%ax [...] With the modification the compiler translate the switch statement into the following jump table fragment: 7ff: 66 83 3e 2c cmpw $0x2c,(%rsi) 803: 0f 87 1f 02 00 00 ja a28 <sk_run_filter+0x26a> 809: 0f b7 06 movzwl (%rsi),%eax 80c: ff 24 c5 00 00 00 00 jmpq *0x0(,%rax,8) 813: 44 89 e3 mov %r12d,%ebx 816: e9 43 03 00 00 jmpq b5e <sk_run_filter+0x3a0> 81b: 41 89 dc mov %ebx,%r12d 81e: e9 3b 03 00 00 jmpq b5e <sk_run_filter+0x3a0> Furthermore, I reordered the instructions to reduce cache line misses by order the most common instruction to the start.

The hash appears immediately before the packet data, not at the beginning of the buffer. This means we can easily use negative offsets from the start of packet data, so adjust the data and length at the top of __efx_rx_packet() instead of wherever we consume the hash. Signed-off-by:
