Wouldn't be useful just to load microcode into fxpX ?
Try ifconfig fxpX link0
$ man 4 fxp

The fxp driver also supports a special link option:
link0 Some chip revisions have loadable microcode which can be
used to reduce the interrupt load on the host cpu. Not all
boards have support microcode support. Setting the link0
flag with ifconfig(8) will download the microcode to the
chip if it is available.

Good luck!
