Hi guys

I am writing a serial network driver. My aim is to bridge two ethernets across a serial bridge.
Unfortunately the channel is noisy and slip and ppp are too unreliable.


The driver appears to work by itself and allows two computers to ping each other across a
null modem cable.


The network driver code permits Linux OS ARPing support for ethernet and MAC addresses
are manually assigned by insmod.


The driver is based on mkiss.c: the packet radio driver for serial ttys except that I have eliminated
ax25 specific code, interfaced to IP directly and added some ethernet support.


Now the problem...

The network driver cannot be bridged to an ethernet card using the bridge-utilities layer 2
bridge tools.


Note that I have successfully bridged between the ethernet card and other ethernet like hardware such as
cisco pci340 WiFi by using these tools.


I am using bridge-utilities-0.9.6-1 on linux 2.4.18-14 and linux 2.20-8.

Any ideas about what I should include as software support in the driver code that will make bridge-utilities
happy?


What does bridge-utilities expect to have available to do its job?
