From d2b59bd9bf8fa0f89604fb55e13b4630c602c094 Mon Sep 17 00:00:00 2001 From: Pau Espin Pedrol Date: Mon, 29 May 2017 11:10:57 +0200 Subject: osmo-bts-trx: Relax validation to allow TRX data bursts without padding Original OpenBTS transcievers add 2 bytes of padding to the end of data bursts, having in total 158 bytes. As those two extra bytes are being ignored after the initial validation, let's relax this validation a bit in order to accept transcievers that decide no to send these two extra bytes.
