Well, I have CONFIG_FW_LOADER_USER_HELPER enabled and Broadcom 
Corporation NetXtreme II BCM5716 Gigabit Ethernet only works when I 
change the source code of bnx2 to use firmware bnx2-mips-09-6.2.1a.fw 
instead of bnx2-mips-09-6.2.1b.fw, then the kernel loads the right 
firmware file. Or should I write a udev custom rule to load the right 
firmware? (I haven't tried this yet)
It seems to me there is a problem here and changing bnx2 source code 
then recompiling the kernel isn't the best solution.
Udev is properly installed in my initrd and in my Slackware 14.0.
