If anyone has any objections, please let me know. ------------------ From: Patrisious Haddad [ Upstream commit c1336bb4aa5e809a622a87d74311275514086596 ] Previously when we had a RAW QP, we bound a counter to it when it moved to INIT state, using the counter context inside RQC. But when we try to modify that counter later in RTS state we used modify QP which tries to change the counter inside QPC instead of RQC. Now we correctly modify the counter set_id inside of RQC instead of QPC for the RAW QP.
