New Revision: 213438
URL: http://svn.freebsd.org/changeset/base/213438

Log:
  RX buffer allocation failure is not an input error. Controller
  successfully received a frame but we failed to pass it to upper
  stack due to lack of resources. So update if_iqdrops counter
  instead of updating if_ierrors counter.
