[ECOS] Dual Ethernet interfaces on i386/pc?

[Stephen Morgan]

Has anyone gotten two Ethernet interfaces working on an i386/pc?  The 
"current" (anonymous CVS) code doesn't support this capability directly, 
so we made some simple-minded modifications that work -- almost.

We changed i386_pc_i82559_eth_drivers.cdl (from 
devs/eth/i386/pc/i82559/current/cdl) and devs_eth_pc_i82559.inl (from 
devs/eth/i386/pc/i82559/current/include) to add eth1 (ETH1), etc.  (Copies 
of both files are attached.)

In all cases, pings to eth0 work fine.  At the start, pings to eth1 work 
fine but, after about six pings, eth1 then sends perhaps 16 duplicates, 
works fine for about six pings, sends about 16 duplicates, and so forth. 
The duplicates have TTLs around 195, versus the expected value of 255, so, 
it sounds as though they're bouncing around inside eCos for 60 hops or so!

We could really use your help!
