Various improvements of qdio error reporting to the upper-layer drivers (qeth, zfcp): - Split QDIO_ERROR_ACTIVATE_CHECK_CONDITION into: QDIO_ERROR_ACTIVATE: qdio termination interrupt QDIO_ERROR_GET_BUF_STATE: QIOASSIST eqbs error QDIO_ERROR_SET_BUF_STATE: QIOASSIST sqbs error Add QDIO_ERROR_FATAL / QDIO_ERROR_TEMPORARY masks to ease recovery decision in upper-layer drivers. - Don't (ab-)use qdio handler errors as return codes for do_QDIO but use standard error codes: -ENOBUFS: temporary target CC=2 condition -EBUSY: unresolved SIGA-W CC=2 busy condition -EIO: I/O error (CC=1, CC=3) - Remove unneeded memory clobber from SIGA-R - Remove EX_TABLE entry on SIGA-W, we want to see these errors Reviewed-by: NUrsula Braun <ursula.braun@de.ibm.com> Signed-off-by: NJan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>
