[dpdk-dev] [PATCH v2] ixgbe: eliminate duplicate filterlist symbols

[David C Harton <dharton@cisco.com>]

From: David Harton <dharton@cisco.com>

Some compilers generate warnings for duplicate symbols for the
set of filter lists current defined in ixgbe_ethdev.h.
This commits moves the defintion and declaration to the source
file that actually uses them and provides a function to
initialize the values akin to its flush function.

v2
* Moved flow filter structs to ixgbe_flow.c.

v1
* Moved flow filter definitions and initialization to ixgbe_flow.c.
