[dpdk-dev] [PATCH v2] net/mlx4: use dynamic log type

[Stephen Hemminger <stephen@networkplumber.org>]

From: Stephen Hemminger <sthemmin@microsoft.com>

This driver should use dynamic log level not RTE_LOGTYPE_PMD.
Other drivers were converted back in 18.02.

This is really a bug, all other drivers use dynamic log levels
by now.

v2 - use rte_log and fix debug logs
