PETH drivers

21 Nov 2000

      Hi,
Does anyone has experience using Pseudo Ethernet drivers for StrongArm-Microengine
communications?
I got the following problem each time I compile with the   -DPETH_DRV flag on
(using Tornado Workbench):

-> ld < my_rtmmvr.out
Loading C:/project2/ARMSA110gnu/rtmmvr.out |
value = 3275480 = 0x31fad8
-> NetApp_GigInit

I am using -DPETH_NUM_DEVS=20, that is 20 PETH devices, because I want to use port
No. 18 for the StrongArm-uengine communication.

Basically the problem is the invocation of the function:   cookie =
muxDevLoad(pethDrvNum, pethEndLoad, pethInitStr, 0, NULL);
that can be found in \IXP1200\SA1_CoreLibs\app_1200\net_app.cpp

My  goal is to transmit a packet from the StronArm to the uengine and viceversa. I
think I should enable the PETH functionality first, but if anyone knows of
another method for doing the same, please let me know ASAP.

Any help would be appreciated.
