Make a distniction between dropped packets and error statistics to allow
a higher level fault management entity to interact with DPDK and take
appropriate measures when errors are detected. It will also provide
valuable information for any applications that collects/extracts DPDK
stats, such applications include Open vSwitch.
After this patch the distinction is:
ierrors = Total number of packets dropped by hardware (malformed
packets, ...) Where the # of drops can ONLY be <= the packets received
(without overlap between registers).
ipkterrors = Total number of erroneous received packets. Where the #
of errors can be >= the packets received (without overlap between
registers), this is because there may be multiple errors associated with
a packet.
v2:
- Added detailed descriptions for ierrors and ipkterrors.
