[realtek] SIOCSIFFLAGS problem witn rtl8139

[Jeff Garzik]

Just to throw something out there in case this is helpful.

I found out recently that SIOCSIFFLAGS is somewhat deprecated... 
 Currently some of the features set/cleared with SIFFLAGS are reference 
counted, which makes a clean set/unset implementation impractical.  I 
found this out the hard way, when Mandrake's security scanner -- which 
checks promisc and other flags -- suddenly started going whacko in 2.4.x 
kernels.
