[dpdk-dev] [PATCH v3 0/6] log de-spamming

[Stephen Hemminger]

From: Stephen Hemminger <shemming@brocade.com>

These patches were sent earlier, updated to current tree.

They make Intel drivers not spam the log with information
messages that cause questions in production.

Unfortunately, developers seem to get attached to log messages
which are not appropriate in a production product

Stephen Hemminger (6):
  ixgbe: convert debug messages to DEBUG level
  ixgbe: raise priority of significant log events
  ixgbe: allow pruning log during build
  e1000: allow pruning log during build
  e1000: change log level of debug messages
  e1000: raise log level of signifcant events

[dpdk-dev] [PATCH v3 1/6] ixgbe: convert debug messages to DEBUG level

[Stephen Hemminger]

From: Stephen Hemminger <shemming@brocade.com>

All the debug chatter messages in the system log causes
complaints from users. Change the INFO messages to DEBUG
for normal startup kind of stuff.

[dpdk-dev] [PATCH v3 3/6] ixgbe: allow pruning log during build

[Stephen Hemminger]

From: Stephen Hemminger <shemming@brocade.com>

The ixgbe driver was not following DPDK convention and
was leaving loggin always in even if LOG_LEVEL was configured
to disable debug logs.

This series is fixing e1000 and ixgbe.
There is the same issue with i40e, fm10k and bnx2x.
I will fix them in the same way.

For consistency, examples/l3fwd-power and eal_common_tailqs.c should
use RTE_LOG instead of rte_log.
