    sys/pci              if_sk.c if_skreg.h 
  Log:
  Do not try to free non allocated memory in error case.
  Do our best to plug some memory leaks (VPD data, jumbo memory buffer,...).
  Log if we cannot free because memory still in use[1].
  Change locking to avoid ''acquiring duplicate lock of same
    type: "network driver"'' and potential deadlock. Also seems to fix LOR #063.
  
  [1] This change does not solve problems if buffers are still in use when
      unloading if_sk.ko. There is ongoing work which will address jumbogram
      allocations in a more general way.
