In many cases, it's enough to simply let the application know that the
call to initialize DPDK has failed. A complete halt can then be
decided by the application based on error returned (and the app could
even attempt a possible re-attempt after some corrective action by the
user or application).
Changes ->v2:
- Audited all "RTE_LOG (" calls that were introduced, and converted
to "RTE_LOG("
- Added some fprintf(stderr, "") lines to indicate errors before logging
is initialized
- Removed assignments to errno.
- Changed patch 14/25 to reflect EFAULT, and document in 25/25
Changes ->v3:
- Checkpatch issues in patches 3 (spelling mistake), 9 (issue with leading
spaces), and 19 (braces around single line statement if-condition)
Changes ->v4:
- Error text cleanup.
- Add a new check around rte_bus_scan(), added during the development of
this series.
Changes ->v5:
- checkpatch.pl cleanup in patch 02/26
- move rte_errno.h include from patch 15 to patch 02
- remove stdbool.h and use int as return type in patch 06/26
Changes ->v6:
- convert all of the initialization calls to RTE_LOG() to rte_eal_init_alert()
- run through check-git-log and checkpatches
- add Bruce's ack to the series
Changes ->v7:
- Squash a bunch of commits
- Make the corresponding BSD side changes
- refactor the PCI probe failure code to be more explicit in the intent
- Remove most of Bruce's acks (with all the shuffling/changes I think the
series should be re-evaluated)
