Move the netif_carrier_off() call from tg3_init_one()-> tg3_init_link_config() to tg3_open() as is the convention for most other network drivers. I was getting a panic after a tg3 device failed to initialize due to DMA failure. The oops pointed to the link watch queue with spinlock debugging enabled. Without spinlock debugging, the Oops didn't occur. I suspect that the link event was getting queued but not executed until after the DMA test had failed and the device was freed. The link event was then operating on freed memory, which could contain anything. With this patch applied, the Oops no longer occurs. [ Based upon feedback from Michael Chan, we move netif_carrier_off() to the end of tg3_init_one() instead of moving it to tg3_open() -DaveM ] Signed-off-by:

The node_map struct can be quite large (516 bytes) and allocating two of them on the stack is not a good idea since we might only have a 4K stack to start with. Signed-off-by:

With reference to latest discussions on linux-kernel with respect to inline here is a patch for tipc to remove all inlines as used in the .c files. See also chapter 14 in Documentation/CodingStyle. Before: text data bss dec hex filename 102990 5292 1752 110034 1add2 tipc.o Now: text data bss dec hex filename 101190 5292 1752 108234 1a6ca tipc.o This is a nice text size reduction which will improve icache usage. In some cases bigger (> 4 lines) functions where declared inline and used in many places, they are most probarly no longer inlined by gcc resulting in the size reduction. There are several one liners that no longer are declared inline, but gcc should inline these just fine without the inline hint. With this patch applied one warning is added about an unused static function - that was hidded by utilising inline before. The function in question were kept so this patch is solely a inline removal patch. Signed-off-by:

Tried to run the new tipc stack through sparse. Following patch fixes all cases where 0 was used as replacement of NULL. Use NULL to document this is a pointer and to silence sparse. This brough sparse warning count down with 127 to 24 warnings. Signed-off-by:

Using this also provides opportunities for introducing inet_csk_alloc_skb that would call alloc_skb, account it to the sock and skb_reserve(max_header), but I'll leave this for later, for now using sk_prot->max_header consistently is enough. 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.
