CRAP in 2.4.18-pre7

I would like to notice that the changes in 2.4.18-pre7 to the
tulip eth driver are apparently causing absymal performance drops
on my version of this card. Apparently the performance is dropping
from the expected 10MB/s to about 10kB/s. The only special
thing about the configuration in question is the fact that it's
a direct connection between two hosts. Well, more precisely it's
a cross-over link between my notebook and desktop.

Here is an excerpt from the lspci command:

00:0b.0 Ethernet controller: Digital Equipment Corporation DECchip 21041
[Tulip Pass 3] (rev 11)
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR+ FastB2B-
        Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
        Latency: 64
        Interrupt: pin A routed to IRQ 11
        Region 0: I/O ports at d400 [size=128]
        Region 1: Memory at cfffdf80 (32-bit, non-prefetchable) [size=128]
        Expansion ROM at cff80000 [disabled] [size=256K]

The motherboard is a SiS735 chip. The card is apparently sharing it's
interrupt
(which I guess could be a cause of the problem) with nearly anything else
on the system:

          CPU0
  0: 654927 XT-PIC timer
  1: 25591 XT-PIC keyboard
  2: 0 XT-PIC cascade
  5: 107 XT-PIC bttv
  8: 283913 XT-PIC rtc
 11: 70064 XT-PIC usb-ohci, usb-ohci, eth0, SiS 7012
 12: 39738 XT-PIC PS/2 Mouse
 14: 198652 XT-PIC ide0
 15: 0 XT-PIC ide1
NMI: 0
ERR: 0

Oh well yes I have added the newest version of the i810_audio.c for
support of the on board sound card - it's working *GREATLY*.

Please revert the changes in question from the pre-patch.
