dexter gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/3061 octphy: record SAACH and TCH BFI Check for bad blocks. If a bad block is detected, increment the block failure indicator (BFI). If a good block is detected, decrement the BFI again. Both happends independently for SACCH and TCH.
