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
