bladeRF support in osmo-trx

[remi]

A recent commit in osmo-trx adds support for the bladeRF xa4:

The commit message points to some limitations:

1) main clock is not a gsm multiple, so it will continously drift
2) small buffer sizes lead to tx gaps that are hard to detect and break everything.

Are these real limitations with the xa4 hardware?

The main clock of the bladeRF 2.0 micro xA4 is 38.4MHz. I'm not quite sure what would qualify as a GSM multiple, but the bladeRF 2.0 micro's crystal based clock is fairly accurate and should not drift more than any other crystal oscillator.

The buffer sizes are a software configuration and in this case look relatively large. I think the commit takes that issue into account by selecting good buffer sizes.

Can you suggest a suitablebasketball stars cache size?
