Unable to create TX buffer recovery queue

Setting MANAGERS=all may be one step but don't some of the

#define CONFIGURE_MAXIMUM_XYZs have default values of 0?

I may need to assign some values to these perhaps?

Have a look at the driver source, elnk.c, line 3525:

if (txDaemonTid == 0)
       if( rtems_message_queue_create( rtems_build_name 
                                       sizeof(struct TXMD *),
                                       RTEMS_FIFO | RTEMS_LOCAL,
                                       &chainRecoveryQueue ) !=  
          rtems_panic( "etherlink : Unable to create TX buffer  
recovery queue\n" );


i.e. the directive, rtems_message_queue_create( ), is failing...

I'm going to guess that you haven't included the Message Manager in  
your application's Makefile. If memory is not an issue (and 128 MB is  
*lots* to play with...), just set the "Managers" variable to "all":

i.e. in your Makefile set

That will circumvent several obscure "gotchyaz"...
