Review at https://gerrit.osmocom.org/6286
Add macros for all ACC bit flags in the rach control IE.
Add macros which document the purpose of each bit in the rach_control.t2
and rach_control.t3 octets. These macros might also be useful for later
work on BTS cell ramping.
This change keeps the existing struct definition intact (t2 and t3 both
remain uint8_t) which means it doesn't affect existing users of this API.
There is at least one line of code, in osmo-bsc's gsm_bts_alloc_register(),
which could already make use of these macros to avoid a magic number:
bts->si_common.rach_control.t2 = 4; /* no emergency calls */
