Hi,

i try to get RTnet up and running, but there are some issues with setup.

Two system are connected via a switch. Both have 2 network interface,  
Intel i210 and Intel 82574L. Only Intel i210 is used by Xenomai/ RTnet.
One system is configured as master in 'rtnet.conf', the other one as a  
slave. If 'rtnet start' is executed following outputs appears.

Master:

> Waiting for all slaves...

Slave:

> Stage 1: searching for master...

RT interface came up as 'rtifconfig' is shown, but both hang on there stages.

At master the dmesg output are floated with messages like:

> [  323.903321] rt_igb: rteth0: Reset adapter
> [  323.905082] TDMA: Failed to transmit sync frame!
> [  323.910082] TDMA: Failed to transmit sync frame!
> [  323.915083] TDMA: Failed to transmit sync frame!
> [  323.920083] TDMA: Failed to transmit sync frame!
> [  323.932087] RTcfg: error -11 while sending stage 1 frame

Anybody knows that error -11 means? I can't find any information on  
this error code.

Thanks
Benji
