svn commit: r228368 - head/sys/dev/et

[Pyun YongHyeon]

Author: yongari
Date: Fri Dec  9 18:34:45 2011
New Revision: 228368
URL: http://svn.freebsd.org/changeset/base/228368

Log:
  Remove unnecessary definition of ET_PCIR_BAR.  Controller support
  I/O memory only.
  While here, use pci_set_max_read_req(9) rather than directly
  manipulating PCIe device control register.
