I've been using rl(4) on 6-CURRENT for about a year now without
problems. I've had it working with/without polling, and with/without
all the mpsafe* sysctls enabled. The only problems I've had with it
were the odd oversized frame being dropped requiring a reset of the
interface. This is on a Toshiba A60 laptop with an onboard RealTek
8139C NIC. Haven't tried with an SMP system (those all have 3Com or
Intel NICs).
