This improves the RFsimulator code to reach a ~40% E2E throughput
improvement (depending on the machines).
Changes:
- reduce ring buffer size
- code cleanup for readability
- set TCP kernel parameters
For FR2 and including analog beamforming, we control the beams via GPIO
on radio units.
In this commit, introduce a configuration option to switch the GPIO
control for different devices: "generic" is the current GPIO control,
"interdigital" configures the GPIO configuration to be used with an
InterDigital device.
