Support one-shot MSI on 5787. This one-shot MSI idea is credited to David Miller. In this mode, MSI disables itself automatically after it is generated, saving the driver a register access to disable it for NAPI. Signed-off-by:

Support 5787 hardware TSO using a new flag TG3_FLG2_HW_TSO_2. Since the TSO interface is slightly different and these chips have finally fixed the 4GB DMA problem and do not have the 40-bit DMA problem, a new hard_start_xmit is used for these chips. All previous chips will use the old hard_start_xmit that is now renamed tg3_start_xmit_dma_bug(). Signed-off-by:

Here's an updated copy of the patch to use fget_light in net/socket.c. Rerunning the tests show a drop of ~80Mbit/s on average, which looks bad until you see the drop in cpu usage from ~89% to ~82%. That will get fixed in another patch...

struct neigh_ops currently has a destructor field, which no in-kernel drivers outside of infiniband use. The infiniband/ulp/ipoib in-tree driver stashes some info in the neighbour structure (the results of the second-stage lookup from ARP results to real link-level path), and it uses neigh->ops->destructor to get a callback so it can clean up this extra info when a neighbour is freed. We've run into problems with this: since the destructor is in an ops field that is shared between neighbours that may belong to different net devices, there's no way to set/clear it safely. The following patch moves this field to neigh_parms where it can be safely set, together with its twin neigh_setup. Two additional patches in the patch series update ipoib to use this new interface.

Account for delayed-ACKs in H-TCP. Delayed-ACKs cause H-TCP to be less aggressive than its design calls for. It is especially true when the receiver is a Linux machine where the average delayed ack is over 3 packets with values of 7 not unheard of. Signed-off-By:

Here goes a patch for supporting TOIM3232 based serial IrDA dongles. The code is based on the tekram dongle code. It's been tested with a TOIM3232 based IRWave 320S dongle. It may work for TOIM4232 dongles, although it's not been tested. Signed-off-by:

The final result is a simpler and smaller code. Note that I'm adding a new member in the struct pktgen_thread called 'removed'. The reason is that I didn't find a better wait condition to be used in the place of the replaced one. Signed-off-by:

I guess I forgot to add it, nah, now it just works: 18:04:33.274066 IP6 ::1.1476 > ::1.5001: request (service=0) 18:04:33.334482 IP6 ::1.5001 > ::1.1476: reset (code=bad_service_code) Ditched IP_DCCP_UNLOAD_HACK, as now we would have to do it for both IPv6 and IPv4, so I'll come up with another way for freeing the control sockets in upcoming changesets.

Instead of doing a memset then initialization of the fields of the scm structure, just initialize all the members explicitly. Prevent reloading of current on x86 and x86-64 by storing the value in a local variable for subsequent dereferences. This is worth a ~7KB/s increase in af_unix bandwidth. Note that we avoid the issues surrounding potentially uninitialized members of the ucred structure by constructing a struct ucred instead of assigning the members individually, which forces the compiler to zero any padding. [ I modified the patch not to use the aggregate assignment since gcc-3.4.x and earlier cannot optimize that properly at all even though gcc-4.0.x and later can -DaveM ] Signed-off-by:

The patch below replaces a divide by 2 with a shift -- sk_sndbuf is an integer, so gcc emits an idiv, which takes 10x longer than a shift by 1. This improves af_unix bandwidth by ~6-10K/s. Also, tidy up the comment to fit in 80 columns while we're at it. Signed-off-by:
