FMComms 2/3/4 is not working with GNURadio v3.11.0.0git-3-g3349d483

[nicolasflorio1]

I'm usung Ubuntu 20.4 and compiled GNURadio v3.11.0.0git-3-g3349d483 from source. When I try to use FMComms 2/3/4 I got the following message:

(NameError("'len_tag_key' is not defined")

So I added:

• id: len_tag_key label: Packet Length Tag dtype: string default: packet_len hide: part

To the file: iio_fmcomms2_source.block.yml

But now I'm getting the following error message: "NameError: name 'rx1_en' is not defined"
