Re: SIOCSIFFLAGS



I just ran across this problem as well.  I have a PCI bus
with a DPT RAID board and a 3COM ethernet board trying to
share IRQ 11.  There were no software options or hardware
jumpers to change the IRQ selection.

To solve the problem, I moved the ethernet board to a
different empty slot. TA DA!  It now magically uses IRQ 5
and the SIOCSIFFLAGS problem disappeared.
