[v31,07/12] eal: initialize log before everything else
Checks
Commit Message
From: Stephen Hemminger <stephen@networkplumber.org>
In order for all log messages (including CPU mismatch) to come out
through the logging library, it must be initialized as early
in rte_eal_init() as possible on all platforms.
Where it was done before was likely historical, based on the support
of non-OS isolated CPU's which required a shared memory buffer.
That support was dropped before DPDK was publicly released.

* **Updated logging library**
+ * The log subsystem is initialized earlier in startup so all messages go through the library.
+
* The syslog option has changed.
By default, messages are no longer sent to syslog unless the ``--syslog`` option is specified.
Syslog is also supported on FreeBSD (but not on Windows).
