This should be putting an entry into the table. 

Make sure this is being compiled. You can also look at the symbols in
the object produced from this source. I use the ebsa driver with two
ethernet devices.....

arm-elf-objdump --syms devs_eth_arm_ebsa285_if_ebsa285.o | grep netdev
00000000 l    d  .ecos.table.netdev.data.ebsa285_netdev0        00000000 
00000000 l    d  .ecos.table.netdev.data.ebsa285_netdev1        00000000 
00000000 g     O .ecos.table.netdev.data.ebsa285_netdev0        00000010 ebsa285_netdev0
00000000 g     O .ecos.table.netdev.data.ebsa285_netdev1        00000010 ebsa285_netdev1

and the same for install/lib/extra.o

arm-elf-objdump --syms extras.o | grep netdev
000000f4 l    d  .ecos.table.netdev.data.ebsa285_netdev0        00000000 
000001f8 l    d  .ecos.table.netdev.data.ebsa285_netdev1        00000000 
000000f4 g     O .ecos.table.netdev.data.ebsa285_netdev0        00000010 ebsa285_netdev0
000001f8 g     O .ecos.table.netdev.data.ebsa285_netdev1        00000010 ebsa285_netdev1
