[Click] Click

[Adam Greenhalgh]

userlevel :
  pros - userspace debugging, flexibilty of driver used, no kernel modifications
  cons - slowest

kernel :
  pros - very fast, little or no extra overheads
  cons - kernel modifications required, e1000 or e1000e or ixgbe
drivers only available (search the mailing list for refs to the last
two) , limited kernel versions supported , tricky to debug.

kernel (patchless - MUST use current git sources)
  pros - faster than user space, no kernel patch required, not limited
to a specific version, not limited to a specific driver
  cons - not complete yet (FromDevice missing ?) , tricky to debug.
