An updated fxp driver patch for bundling receive interrupts, thus saving a noticeable amount of CPU overhead for interrupt processing, can be found at http://www.tel.fer.hr/zec/BSD/fxp/. New features include: - control of microcode parameters through sysctl variables - activation/deactivation of microcode without bringing the interface down - independent control of microcode parameters/activity for each fxp interface instance - new parameter hw.fxp.size_mask - hw.fxp.int_delay is now defined in microseconds, instead of microcode time-counter units The microcode should work on many revisions - if not all - of Intel 8255* chipset, but the BSD driver is currently tested only on 82558-B0, so I would really appreciate any feedback on driver functionality/stability on other chipset revisions.
