2010-08-02cxgb4: support running the driver on PCI functions besides 0Dimitris Michailidis
Add support for running the driver on any PCI function. Mostly this entails replacing a constant 0 in a number of calls with the variable function number. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-08-02cxgb4: fix TSO descriptorsDimitris Michailidis
Commit 1704d74894912b8ecc3e95cecd7bde336a0b1bf2 ("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.

2010-08-02tg3: Improve small packet performanceMatt Carlson
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.

2010-07-31bonding: prevent sysfs from allowing arp monitoring with alb/tlbAndy Gospodarek
When using module options arp monitoring and balance-alb/balance-tlb are mutually exclusive options. Anytime balance-alb/balance-tlb are enabled mii monitoring is forced to 100ms if not set. When configuring via sysfs no checking is currently done. Handling these cases with sysfs has to be done a bit differently because we do not have all configuration information available at once. This patch will not allow a mode change to balance-alb/balance-tlb if arp_interval is already non-zero. It will also not allow the user to set a non-zero arp_interval value if the mode is already set to balance-alb/balance-tlb. They are still mutually exclusive on a first-come, first serve basis.
