Packet socket: mmapped IO

When configuring the kernel, the configuration help suggests disabling the
option "Packet socket: mmapped IO". Is there any reason for choosing the slower
implementation without mmap?

IIRC there were alignment issues for memory mapped boards. I read about
this in the documentation of earlier version of 3c59x boards.
But I think it is solved (for those boards at least).
