Subject: Usage of mdelay() inside Interrupt

Hi,

while browsing the sourcefile of lib8390.c in
drivers/net/ethernet/8390/, i noticed that inside
of ei_rx_overrun(), which is called from inside
a Interrupt handler, mdelay() is being used.
So i wonder if the usage of mdelay() inside the
Interrupt handler may cause problems since waiting
~10ms in Interrupt context seems a bit odd.
