Realtek 8139 with rl(4) driver -> Poor performance

[Gabriel Lavoie]

Requested commands:

Before a problem happens:

[root at headless ~]# sysctl hw.busdma

I got a Samba copy error at this point:

[root at headless /home/wildchild]# sysctl hw.busdma

Now the networking is really erratic. I have a huge slowdown with SSH and
I'm unable to copy files on the computer anymore via Samba. I must reboot to
get back the full performance.
