Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6 

* master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6:
  [ATM]: [lec] use refcnt to protect lec_arp_entries outside lock
  [ATM]: [lec] add reference counting to lec_arp entries
  [ATM]: [lec] use work queue instead of timer for lec arp expiry
  [ATM]: [lec] old_close is no longer used
  [ATM]: [lec] convert lec_arp_table to hlist
  [ATM]: [lec] header indent, comment and whitespace cleanup
  [ATM]: [lec] indent, comment and whitespace cleanup [continued]
  [ATM]: [lec] indent, comment and whitespace cleanup
  [SCTP]: Do not timestamp every SCTP packet.
  [SCTP]: Use correct mask when disabling PMTUD.
  [SCTP]: Include sk_buff overhead while updating the peer's receive window.
  [SCTP]: Enable Nagle algorithm by default.
  [BNX2]: Disable MSI on 5706 if AMD 8132 bridge is present.
  [NetLabel]: audit fixups due to delayed feedback
