[dts] [PATCH]fix: set 100g ixia configuration disable

[Qian Xu <qian.q.xu@intel.com>]

This patch fix an issue that if the ixia.cfg doesn't set the enable_rsfec. 
1. Change the enable_rsfec to force100g for better understanding. 
2. Set force100g disable if user didn't set the value in config file.
