[dpdk-dev] [PATCH v2 1/1] ethdev: remove the imissed deprecation tag

[Maryam Tahhan]

Remove the deprecation tag and notice for imissed as it is a generic
register that accounts for packets that were dropped by the HW,
because there are no available mbufs (RX queues are full). imissed is
different to ierrors and can help with general debug.

Fixes: 49f386542af4 ("ethdev: remove driver specific stats")

v2:
 - Clarify why imissed is no longer deprecated.
 - Improve definition of imissed in the documentation.
