Problem configuring ethernet interface for NFS in rtems-libbsd

[vivek kukreja]

Hello Sebastian,

I figured out my error. I was using a smaller stack size until last year so the nfs client hung up on initialising. I reset some config values and its working now. Thank you for your help.

Regards,
Vivek
