Merge branch 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6 

* 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6:
  - cxgb3 engine microcode load
  cxgb3 - Fix dev->priv usage
  qeth: Drop ARP packages on HiperSockets interface with NOARP attribute.
  qeth: provide specific message for OSA-adapters exclusively used
  qeth: crash during reboot after failing online setting
  qeth: Announce tx checksumming for qeth devices in TSO/EDDP mode
  qeth: dont return the return values of void functions.
  qeth: enforce a rate limit for inbound scatter gather messages
  qeth: ungrouping a device must not be interruptible
  netxen: fix crashes during module unload
  netxen: Avoid firmware load in PCI probe
  PS3: fix the bug that 'ifconfig down' would hang
  IOC3: Program UART predividers.
