[Click] click for FreeBSD compile error

[Pekka Nikander]

You can check out a working version from https://github.com/pnr/click

You need to pull the freebsd-kernelmodule-patches branch:

  git clone git://github.com/pnr/click.git
  git checkout freebsd-kernelmodule-patches

Please let us know how it goes.  It should work with both 7.X and 8.X, but so far we've done only minimal testing.  So, please report any bugs you encounter.

We haven't yet asked it to be merged since we are still looking at better ways to deal with scheduling.  Right now we are using netisr on 7.X and the alternative method on 8.X, as we haven't got netisr to work on 8.X.  Hopefully we will get both working on both, at some point.
