[tulip] Tulip and PowerPC endian issue?

[Jim Rowe]

As  you suggested I used the tulip driver from Scyld in the
netdrivers-3.3.tgz package and I still get the same byte swapped MAC
address.

I built the module with:

make KERN_INCLUDE=/usr/src/linux/include MODULEDIR=/tmp/pcmcia-test
PCMCIA=/usr/src/linux/include/pcmcia

Then:
cd /lib/modules/2.4.19-rc1-acms1/kernel/drivers/pcmcia/
insmod pcmcia_core.o
insmod yenta_socket.o
insmod ds.o
cd /usr/src/netdrivers-3.3
insmod pci-scan.o
insmod tulip.o

The first 32-bit word is still byte swapped, however the second now
shows zeros instead of the 79:F0 as last time.

Again my MAC address should be 00:10:7A:69:F0:79.

Here is my log file:
