svn commit: r231742 - stable/8/sys/dev/netmap

[Luigi Rizzo]

New Revision: 231742
URL: http://svn.freebsd.org/changeset/base/231742

Log:
  use 4096 instead of PAGE_SIZE to determine the initial size
  of the memory allocated for netmap. Apparently the previous
  value fails with an integer overflow on stable/8-IA64
  (4M pages ? curious that it does not fail on stable/9 and head)
