I can't remember the exact wording of the error message I was getting, but under a very high load (all four ports spitting out about 90 Mbps), the card would frequently complain that some buffer was full and it couldn't send anymore. The only way to get the card back was to do an ifconfig down up on all four ports... It looked very much like mbuf exahustion except that mbuf's were still available according to what I was seeing. I guess there is a small problem in the sf driver, but I didn't get around to trying to fix it. (Device driver tweaking is not really my area of expertise...) If there is interest I can try to dig up the old email in which I was describing the problem... I don't think I posted it to this list at the time, it's more likely I sent a private email to the driver's author. Then again, these problems occured under 4.3 and 4.5, can't tell if this was fixed in more recent revisions of the driver.
