[srslte-users] RLC discarding eMBMS data

[Justin Tallon]

Hey Claus,

I will take a look at these traces for you.

In the mean time one check you could do is replicate the experiment with
srsenb, srsepc and srsmbmsgw to ensure the same setup using our software
works correctly as a benchmark, then we can work out what is set
differently in your amarisoft software.

Regards,
Justin
