Even though the vendor may produce low-end ethernet controllers
the controller would be sufficient enough to handle most traffics
for personal/home usage. CPU is fast enough to saturate 100Mbps
link with this controller and your bottle-neck would be PCI bus
because you would use 4 ethernet controllers at the same time.

I just committed the patch to HEAD(r211648) and will MFC the change
after 1 week. I made slight change to original patch so the tunable
is now set in /boot/loader.conf instead of /boot/device.hints. You
can get the same effect by adding the following line to
/boot/loader.conf file.

dev.rl.0.prefer_iomap="0" # for rl0
dev.rl.1.prefer_iomap="0" # for rl1
dev.rl.3.prefer_iomap="0" # for rl3

Thanks for testing and reporting!
