[PATCH 2.6.19 3/4] ehca: Kconfig: activate scaling code as default to prevent drop packets (UD)

Hello Roland!
Here is a small patch of ehca's Kconfig that activates scaling code as default.
After several measurements we saw that this feature prevents drop packets (UD)
in stress situation. Thus, enabling it helps to improve ehca's bandwidth through
ipoib.
Thanks!
Nam
