Commit 1704d748 ("cxgb4vf: small changes to message processing structures/macros") was incomplete and causes cxgb4 to write bad TSO descriptors. Fix that up by reverting the offending part of that commit and adjusting field accesses now that they are one level deeper. Signed-off-by:

This patch moves most of the phy related flag definitions over to the phyflags member and changes the code accordingly. Reviewed-by:

This patch deletes the link_config.phy_is_low_power flag and creates a new phy_flags device member to store all phy related settings. All the code is converted accordingly. Reviewed-by:

smp_mb() inside tg3_tx_avail() is used twice in the normal tg3_start_xmit() path (see illustration below). The full memory barrier is only necessary during race conditions with tx completion. We can speed up the tx path by replacing smp_mb() in tg3_tx_avail() with a compiler barrier. The compiler barrier is to force the compiler to fetch the tx_prod and tx_cons from memory. In the race condition between tg3_start_xmit() and tg3_tx(), we have the following situation: tg3_start_xmit() tg3_tx() if (!tg3_tx_avail()) BUG(); ... if (!tg3_tx_avail()) netif_tx_stop_queue(); update_tx_index(); smp_mb(); smp_mb(); if (tg3_tx_avail()) if (netif_tx_queue_stopped() && netif_tx_wake_queue(); tg3_tx_avail()) With smp_mb() removed from tg3_tx_avail(), we need to add smp_mb() to tg3_start_xmit() as shown above to properly order netif_tx_stop_queue() and tg3_tx_avail() to check the ring index. If it is not strictly ordered, the tx queue can be stopped forever. This improves performance by about 3% with 2 ports running bi-directional 64-byte packets. Reviewed-by: -

tg3 commit e7126997 entitled "tg3: Preserve PCIe MPS setting for new devs" attempted to ensure the PCIe link negotiated Maximum Payload Size (MPS) setting was 128 bytes for all devices that didn't support higher speeds. The 5784 device was mistakenly added to this list when it shouldn't have. This patch removes the 5784 ASIC rev devices from that list. Reviewed-by:

The tuple got from unique_tuple() doesn't need to be really unique, so the check for the unique tuple isn't necessary, when there isn't any other choice. Eliminating the unnecessary nf_nat_used_tuple() can save some CPU cycles too. Signed-off-by:

some users of nf_ct_ext_exist() know ct->ext isn't NULL. For these users, the check for ct->ext isn't necessary, the function __nf_ct_ext_exist() can be used instead. the type of the return value of nf_ct_ext_exist() is changed to bool. Signed-off-by:

The other calls to kmalloc in the same function use GFP_ATOMIC, and indeed two locks are held within the body of the function. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier f; @@ *f(...,GFP_ATOMIC,...) ... when != spin_unlock(...) when != read_unlock(...) when != write_unlock(...) when != read_unlock_irq(...) when != write_unlock_irq(...) when != read_unlock_irqrestore(...) when != write_unlock_irqrestore(...) when != spin_unlock_irq(...) when != spin_unlock_irqrestore(...) *f(...,GFP_KERNEL,...) // </smpl> Signed-off-by:
